Is there a switch on the unit to manually turn it on or does it only turn on by the remote?

Yes there is a button to push that will turn it on but that does not work either.

Sometimes there are sensor switches on the covers that will keep the unit from turning on if it thinks the cover is off. If yours has one maybe it got loose or bumped when you had it apart.

I will look mor closely at that in the AM but i doubt that is the problem. i dont see anywhere that there is any kind of intreupt switch connected to the covers at this time. it is my feeling that the problem is the PC board. I have one on order and it should arrive in a couple of days.

Check the wiggle pins.

If i knew what they are….

Wiggle pins ... is purposeful obtuse nonsense.

In other words being a 🍆

It's as obtuse nonsense as performing DIY and then thinking you should run to the internet for more wizzardry thinking someone is going to offer you some psychic magic for your DIY lack.

Maybe you get lucky spending $200 for a board, or you just keep changing parts until you realize you'll never fix it. (the world may never know, much like how many licks it takes to get to the center of a tootsie pop sucker)

Mini splits are essentially expensive throw away units. Of course your mileage will vary... you're in HVAC land.

Thanks for the encouragement. I am aware now that they are throw away units because the wall unit circuit board is obsolete and pretty much unavailable. So I can accept that and call my local “Austin Air Companie” and they bring a new compatible wall unit out that costs $350 and then charge me 1500$ to install it and add another $350 to the wall unit as their mark up or i can take a shot at a $40 part and maybe it works. Other than that do you have any thoughts that might be helpful?

@klem1 and @Austin Air Companie,

You two rarely contribute anything other than to criticize posters who are looking for help or those attempting to help them. Might I suggest you add more fiber in your diet?

hoho223, the board could possibly be repaired if you can identify, source, and DIY a failed component ... or find an electronics servicer willing to do it.

I once repaired a Frigidaire portable AC that had been set aside to the junk room at work after it failed and was replaced with another portable. The needed part was (surprisingly) available.

it is my feeling that the problem is the PC board. I have one on order and it should arrive in a couple of days.

I assume you ordered the controller board. If you want the main circuit board I found it here:

PC BOARD 6231917735

Have you found the schematic? If you have a voltmeter I suggest checking the voltages before buying more parts. I have never tried to repair a mini split, but I would not describe them as throw away items in my opinion. A window air conditioner or a thermostat are throw away items.

hoho223,

I can understand your pain, but this is how capitalism works.

A company regardless whether it's HVAC or selling units of something doesn't sell those things for what it costs to buy them.

The others on the board will claim that helping you is for you to take up a new career asside from your regular way of making a living and take up circuit board trouble shooting and repair.

That is helping here in DIY land. These characters aren't going to teach you... but in their minds they've help you. A crazy place to reside if you ask me... but those are your choices.

I grew up without Air Conditioning... that's another choice for you that is 100% free.

You know it's the truth, because it doesn't go down easy. Or you can pretend someone else is helping you by suggesting you begin a new career in fixing obsolete mini splits.

I would rather be honest even if you don't like it.

I agree with your capitalism snark because I use it often also. I also say if you don't like paying so much in taxes, don't make so much money. I've got the money to even call "Austin Air Companie" right now and have them make a home visit and bring the parts to fix or replace my a/c.

I became acutely aware of the add on to contractor purchased parts when we built our house....even though I shopped for them and paid for them myself.

Your comment about DIY land is that all DIY forums are crazy places to reside and that you feel we as self help people shouldn't be on them and the people giving advice shouldn't be giving advice....but here you are. So let me ask you this...is there a fuse in the outside unit? I say no because there is power to the inside unit and I see no fuse symbol in that schematic.

I grew up with no a/c also but I am done with that lifestyle as much you are.

I am not looking for a new career in HVAC. That's why I will be going to "Heating Help" forum after this regarding a boiler. (I've gotten good honest help from those members before.) I don't know how to pressure check an a/c unit, charge a unit or anything like that. However I am smart enough to know where the electricity comes from and how it flows. I also know how to unplug something and replace a part that is critical to the functioning of something.

If I fail to fix my unit with the small PC board replacement I may move on the main board in the wall unit. After that....I'll let you know. My mini split isn't obsolete until there is a leak in the copper.

"However I am smart enough to know where the electricity comes from and how it flows."

Had you included that information at the beginning I would have told you a quality multimeter is all you need to nail down the problem. I truly want to help but realize I muffed it so will respectfully defer to Chas Ross for tips on using meter or evaluating diodes,resistors,capacitors,transformers and other components on the circuit boards. As Dadoes suggested,the board can likly be repaired by simply replacing a failed component. If unrepairable you will at least be certain board is defective before replacing it. I don't understand your remakes about bran flakes Chas Ross but here's an opportunity to help by putting your expertise to use guiding OP through testing boards.

Update: I have now removed the wall unit main board and found that the glass tube fuse is indeed popped and the back of the board is visibly marked. The fuse is soldered into the boards circuit so I had to cut the connecting wires of the fuse to test it after I disconnected the board from the unit. A local electronics store that i was seeking help from thought that a piece on the board was also baked because it appeared to have lifted a bit creating a slight dome which isnt supposed to be there..

@klem1

I'm not an electronics expert and I won't begin to offer troubleshooting advice at the board level. Your track record of "helping" houzzers is easily investigated. I don't think you'll score well on that test. I've concluded that you're full of stuff that might be remedied by the addition of more fiber in your diet. I'm neither a dietician nor a medical professional, just someone trying to help.

I became acutely aware of the add on to contractor purchased parts when we built our house....even though I shopped for them and paid for them myself.

You over paid for those as well, because the place you bought the parts don't sell those parts for what they can buy them for. In order to defeat capitialism you need to be the one making stuff and then marking it up to make a profit.

Mark it up too much, no one will buy it. They will resort to measures of which you show on this board hoho223. Mark it up too low and it's not worth the time let alone the aggravation.

Break out that solder iron and start fixing those obsolete boards. The mini split market probably makes up some where between 5-10% of the US. Thinking illogically a 5-10% market is a market that is full of growth and wild opportunities.

Imagine all those mini splits you can save and you will control this market.

When you go to the grocery store every week: You do realize that store is making a profit on everything you buy there. So when are you going to start growing and raising your own food to defeat the capitialism on that front?

Ah helping. Such and eye opening experience. WOW!

Your internet provider? you pay them right? When are you going to make your own internet connection?

Your computer / phone to access the internet? They made a profit off you. When are you going to make those things yourself?

"In order to defeat capitialism you need to be the one making stuff and then marking it up to make a profit." Really? That's not defeating capitalism, Ray, that's participating in it. You might want to stick to HVAC topics or risk getting your 6th grade diploma recalled.

The builder was local. He was not a mass builder. He dealt with a local hardware store. I wasn’t buying building materials. i was buying the faucets, towel bars, toilets toilets, etc etc. Not all of it was installed by him. The most he would have gotten as a discount was sales tax because he wasn’t a bulk buyer.. In addition, I did the shopping. Not him..
Your other analogies are bogus. I like to do things with my hands so that makes me anti capitalist? I never knew that. The next time I need brakes on my RAV, F150 or Lexus I won't change them myself. Next time I need an exhaust on my truck I wont buy it and install it myself. When my tractor needs servicing I'll truck it to the Bobcat dealer and have them do it. When i have a firebox installed next time I won't build the facade by myself. I'll have a master carpenter come in and do it. I'll stop cutting my own firewood for the firebox and start buying it. You get the idea, I'm sure.

hoho223,

Well the whole reason we are here is because you can search prices on line to buy something yourself then comparing that to the quotes you receive but from that you don't deduct all the costs involved to running a business.

The service industry that comes to your home all you have to do is pick up the phone and schedule an appt.

But all these other things you mention: you have to physically go there yourself. (labor, wear and tear on your car, risk of ticket, accident etc)

You can afford all these other things but you can't afford to pay for professional AC repair service? Did you fail to realize this?

Or is it that you just don't want to pay? There is a free way out that we already discussed on this thread. It won't be that comfortable but that's the cost of free. (free always has a cost... time, discomfort being the big two invisible costs that people love to ignore because we getting it FREE) -- the gimmick is hard to beat unless you come to Truth HQ.

I grew up without air conditioning. (I wouldn't recommend it, but it's free)

Who do you think installed the three sanyos i have?

How did that work out?

There's 2 sides to every coin, just because you don't look on the other side doesn't mean that story doesn't exist. There isn't much you're going to tell me that I haven't seen in person over the past nearly 30 years I have been doing this profession in person. Not just barking on a forum board.

I've been to homes with units in pieces because home owner thought some enthusiast made more sense than I did. You wouldn't be the first person in 30 years I've met who thinks they know better than what I would do for certain scenarios. I suppose this might be why you have mini split vs a real HVAC system. You fell victim to the salesman equipment pitch... that now leads to more equipment again. Cutting the pro out has it's consequences.

So you could solve the problem by going and buying 3 more units? And how long would that last? You know the answer to that by a pretty close margin.

I suppose you may think I never have any AC trouble of my own at my own house(s). That's a myth if you think that. (they all break)

1. I didn’t install them.

3. I built my house (1999-2000) with baseboard heat. I have no duct work.

4. We didnt have a/c for several years after building.

5. I saw your ads. They’re cute.

6. Dont understand your comment about 3 more units.

7. Who do you call for your a/c service because you are right.…..They all break down. Hope you get a good deal.

8. I expect my a/c units to remain serviceable for as long as i need them. I am 75, college educated, retired military, retired civilian and expect to be around for at least 8-10 more years.

6. Dont understand your comment about 3 more units.

Your comment here: Who do you think installed the three sanyos i have?

+ we're in a thread talking about DIY + the cons of spending money on comfort.

Led me to believe you installed them. Which essentially proves my psychic ability is no where near my working in person ability. I don't service all areas. From the extent of this conversation it doesn't sound like you live anywhere near me. (Katy, Texas area)

7. Who do you call for your a/c service because you are right.…..They all break down. Hope you get a good deal.

This is what I do... me, myself and I. For me it's not about a fading "good deal". It's more in the lines of performance, efficiency and pay back by a reduction in utility bills. From the rental house side it's to have tenants not complaining and calling me complaining it's too hot here or too hot there. (we had record heat here last year with temps over 100F as early as May. Not a single complaint from my tenant about AC)

I am in rental houses all summer long where "we're trying to profit from $200-500 a door debt burden" with an AC that has seen better days. (These are rental homes I don't own, other people own.) This isn't bragging, it's telling the story so you don't make something up in your head either.

8. I expect my a/c units to remain serviceable for as long as i need them. I am 75, college educated, retired military, retired civilian and expect to be around for at least 8-10 more years.

My dad may have served around the time you did. He served in the Marines. I think his stint was in the neighborhood of 4 or 5 years, some time in the 50's if I am doing the math properly in my head. Thanks for your service.

Yeah I expect the same out of my AC units as well. The government that makes the rules I have to follow has other ideas. By 2025 the R410a phase out will take hold. Prices will jump -- hard freeze on any new equipment. The new refrigerants have problems. Will be short lived because they don't hit the targets set by the Kigali Amendment to the Montreal Protocol that was signed by then President B. Obama.

Given what I see are true and honest facts / how equipment & refrigerant phase outs work due to banned refrigerants --- the costs will only continue to go up. They've already gone up by a wide margin thanks to guess who? (The inflation is only transitory crew -- let's keep spending)

I doubt these Sanyo units of yours will make another 8-10 years.

If I make it that far I will likely replace all mine at the ripe age of 70 with the realization I may need repairs as soon as 3-5 years later as this is the current cycle we are on. You'll never eliminate the need for service & repairs, that clock starts the day you put the new equipment in.

I was just at a house yesterday that got a so called good deal put in by someone else. They can't find that guy... they called another company before me and they wanted to replace the whole system because they don't work on so and so brands. I go out there and replace a switch on the condenser and she's running again. The unit was only about 7 years old.

Final update...I know you have been waiting. I had an electronics tech replace a soldered in fuse on the main PC board. Still didn't work. As I said before, a replacement board was not available because the unit is obsolete. Replaced unit with a 18k BTU Mitsubishi. Just in time for us to go onto vacation to Norway and Sweden. We're now back and its working like a charm because it is now 90's weather.

Thanks to all for their help and the discussions.
