My DH is a scientist and he says that it is likely due to the very cool temps of the door. I can't find any other commentary on the problem. I have only had it happen on my Miele ovens when I was doing very moist baking . Hope this helps. c

thanks for the reply. I do know that condensation is normal, just thought this to be a bit excessive seeing as it's dripping out.

With my Bluestar oven, condensation happens during warm-up and yes it is absolutely normal and expected. What isn't expected is for the condensation to drip out. I have never noticed that before. If I were you, I'd contact Bluestar customer support and ask for advice.

I have been trying to contact them all day via phone with no luck. just rings and rings. I will try sending an email.

we had an issue with the door being damaged when we first got it, and they promptly sent a tech to replace the skin. I'm wondering if this may be related to the repair (maybe a gasket or something). wish me luck!

Please keep us posted when you get hold of them. I am curious to hear how things turn out.

Condensation is normal and varies based on weather and altitude. It shouldn't drip like that though. Poor combustion causing excessive condensation? Bad door seals?

I have been trying to contact them all day via phone with no luck. just rings and rings.

The rather constant reports like this really don't sound good for Bluestar.

So I sent an email request for service on Monday, still haven't heard back. Left a voicemail also.

I'm concerned because I have owned it for one year on Feb. 2, so my warranty will be running out.

anyone else with a BlueStar able to take a look at the top of their kick plate (below the oven door) to see if there is any signs of this?

thanks again

I am following this because I was all set to buy a Bluestar for our remodel this Summer. I am so worried that I will have to give up the idea due to lack of customer service. I will be watching to see your follow up .

Did you buy direct from them or from one of the stores that carry their appliances? I assume if I got it from an appliance store chain that carries their products here in VA that service would be covered by the dealer not Bluestar ....what do you think ?

We bought ours through an appliance dealer. I had not yet tried reaching out to them, I will give that a shot today. I was trying to contact BlueStar first to inquire as to wether or not this was considered normal.

I will say that we are extremely happy with the performance of our range, and we have had no issues with the cooktop. I'm thinking and hoping this will end up being a minor issue. I would still likely buy the range again.

So I sent an email request for service on Monday, still haven't heard back. Left a voicemail also.

Poor response is one thing but no response like this sounds like a company going under. I hope that's not the case.

Just checked my 48 inch range and yes it does have small dried water marks. Both oven doors are vented through the entire door. If you look through the top of the vent on the door you can see through to the bottom. So it has nothing to do with door seals. I think it's normal. I have never had any water drip on the floor so I wonder if you get more condensation due to environmental factors.

Thanks for checking yours out.

I did finally get ahold of someone there today and they were very apologetic. they have assured me that any potential problems would be made right but they required some extra pictures etc. I will keep everyone posted, but I think I should be in good hands now.

Alex, I have a 30 inch RNB, have often noticed condensation on the oven door, but never noticed dripping. I did just check, and though it is hard to see, there does seem to be some staining on the top of the kick plate. My WAG, is that the amount of condensation varies based on a number of factors. I just did a search and found this on the Wolf website wolf faq on condensation

Another update. BlueStar is sending an authorized repair technician to take a look and make the appropriate repairs.

I decided that because I am at the end of the warranty period, I would look the range over for any other issues. I happened to find the painted coating on the back wall and the lower oven pan were both showing scorch marks and burnt paint. I imagine some of this is normal given the proximity to the oven element. Regardless, BlueStar is sending me a replacement lower oven floor pan and having the technician install a new rear wall/pan.

I feel they are definitely trying to work to resolve my issues. I will update again once repairs are done. thanks again to all!

so impressed with Blue Star's response. Thank you for getting back about this and will watch for the update after repairs. I am heartened as I REALLY want the RNB 30" :)

Hi Alex, I know this post is a year old, but I just recently had my new Bluestar all gas 36 inch open burner range installed, and we absolutely love it, except for the same issue you reported with the condensation. We had absolutely no trouble getting ahold of Bluestar and asking about the condensation issue. We sent them pictures of the excess condensation and they have sent the pictures to the technicians and are waiting on a response, they told me they have some staff out right now, and with the issues going on right now we totally understand. I was just wondering what they did for your range while we are waiting for a response. Other than the excessive condensation the range performs beautifully.

burning natural gas (methane) produces water and carbon dioxide. That condensation is what you see on the glass door. What shouldn't be happening is it leaking out. probably a misaligned door seal.

The technicians at Bluestar reviewed the pictures and videos I sent and they said that condensation is normal on a gas range. So other than the condensation, which apparently is completely normal, the range performs beautifully and we are very happy with it.

delray, I took a look at the oven seal and it does not look out of line or warped or anything, I appreciate the comment tho, it didn’t hurt to check it out just in case.

I am wondering if environmental could have a play in the amount of condensation as well?We like to keep our house on the cooler side and with the range being so large, I’m wondering if going from so cold to rapidly hot in a cool room to boot, could be causing some of the excessive condensation? I don’t know?

Condensation happens as long as the oven door hasn't reached a sufficiently high temperature. As soon as the oven is done preheating, condensation should stop. So, yes, if your house is unusually cold, then you'd expect that it would take longer for the oven to preheat. And that would also result in longer preheat times.

These are big ovens. They do need a good while to come up to operating temperatures. I need to preheat my 30" RNB for at least 20min and preferably 40min, if I want temperatures to be really even. I'd imagine that a 36" range takes longer. That's the trade-off with having these really humongous oven cavities. They are wonderful for large meals and they bake/roast really reliably, but they do take a while to set up.

For day-to-day use, I often prefer my small 24" wall ovens. Much faster to preheat, but of course also significantly smaller capacity. But for many regular kitchen activities, that's not a problem.

Here's what ours looks like right now with something cooking in the oven. You can see the little puddle.

I don't normally see that on our 30" range. But I do get some condensation during preheating. I could imagine that depending on relative humidity and on room temperature, some people get more condensation. And bigger ovens probably take longer to preheat and thus get even more condensation.

In either case, it looks like only about 1ml of water (give or take). That seems pretty harmless and I wouldn't worry about it.

We are not worried about it. Didn't even know it was doing that until I read this thread on here. We usually just leave it. On Sundays when we do house cleaning we just wipe it off. Ours has never dripped on the floor though.

Thanks all for the input, I appreciate it!

We weren’t really worried about it, especially because the range was working as it should, we knew that some condensation was normal, it just seemed like so much condensation to me that I thought why not check with Bluestar just to be sure, I posted a picture to show how much condensation it gets during initial preheat, it always goes away slowly once it gets to temp tho...... thanks again everyone!

My RNB30 also drips onto the floor, which i find unacceptable. I've never had this occur with other ovens, even ones more than 80 years old that have no door gaskets at all (condensation yes but dripping no). Like you the dripping comes from the within the oven door and then exits the holes at the bottom of the oven door. One thing i noticed is that my oven has no gasket across the bottom. This means that quite a bit of hot air escapes down to the kickplate panel, which gets excessively hot. In fact i burned myself on it when looking at the water dripping. Luckily i have old linoleum and the water did no damage to the floors. Has anyone found a solution? Like other users, I've had to tolerate numerous issues resulting from bad design on these stoves. The side panels also get very hot, and there's no way I'd install this stove against wood cabinets with zero clearance. The insulation on this things is really a joke. Also i did an experiment today. My 30" Tappan which is supposed to have an 18kbtu oven burner took 13 minutes to reach 450...the Bluestar with a supposed 30k btu burner took 22 minutes to reach 450 degrees. Yes the Bluestar oven is marginally bigger, but the preheat times are really unacceptable.

I would check the actual oven temp with a reliable thermometer, rather than the dial on the range. Doesn't fix your water issue though

Bluestar sent a repair technician to our house to thoroughly go over our range. The technician said he was very familiar with the Bluestar range and actually was ordering one for his kitchen as he liked them so well. He did a check of all the top open burners even tho we have had no issues with them, took the bottom pan out and checked the burner to make sure it was in order and had no issues, then the same with the broiler. He then turned the oven on and looked at the condensation and told me it was completely normal and that the amount of condensation depended on several factors, including the size of the oven to the environment of my house, which we do keep around 67 during the winter.

I did ask about the oven seal not going all he way around the cavity and he said that was the way it’s manufactured and it’s supposed to be that way for venting purpose, which is causing heat/ moisture to drip out some on the kick plate, which obviously will be hot.

We did have an issue with a “banging noise” prior to the techs visit, since he found nothing wrong with the range whatsoever, he asked how long I did the burn-in and I told him I followed the instructions per the manual, he told me it was more than likely the metal bottom pan and that since it was a new range it needed more break in time and to run the oven on 500 for 2 hours, which I did and we’ve not heard the noise since.

We had our range professionally installed and it’s inbetween wood cabinets, which not only the installers said was fine, but Bluestar said it was fine prior to installation as we called and asked them prior to purchasing the range to be sure. We haven’t obviously pulled the range out to look at the cabinet, but as far as hot goes, only the bottom kickplate gets hot, mostly on the top, while the front of the kickplate gets really warm, its not as hot as the top of it. As far as the door goes, it really doesn’t get hot at all, even when I ran it for 2 hours on 500, it was warm to the touch, but not hot.

We just had the range installed around 3 months ago, and its a 2019 model year per the serial number, so I’m not sure if they had a design change or added more insulation since you purchased your range? I did read some older reviews before we bought the range that said the door was getting super hot while in use, I contacted Bluestar to ask about this issue and they told me they changed the door design recently, in 2016 I believe, so maybe if you contact them they maybe able to help you with that issue if your having it?

Besides the condensation which I now know for sure is normal, along with the longer preheat times (which I asked the technician about as well and was told it was normal due to the cavity size) We are happy with the range, and if I knew about the condensation prior to purchasing the range, I would still have purchased it.

I love the open burners, they are fabulous and so much easier to keep clean than sealed burners, I’m sorry I didn’t switch to them sooner.

Sorry for the long post, I hope it helps some..... 😊

Kelly thank you so much for your thorough reply. I feel much better knowing that the technician reported your oven is working property. My oven was manufactured in late 2008, so it has the older style door. It is one of the few that still has the old style hinges. I wish it would have broken years ago when bluestar was sending the new doors for free. Because of the age of my stove, if the hinges fail (even though a known defect) I'd have to pay over 400 for the new style door and hinges (not including installation)..so i keep a closed watch on the hinge condition. I also have the old style oven floor with the aluminum rivets that failed. I repaired that by replacing them with stainless steel rivets rather than paying several hundred dollars for a new oven floor. Bluestar technical service seemed ok with this solution because they provided me with the correct size of rivets so I could purchase them. After 10 years, the oven burner is just about ready to be replaced. the burner tube develops a hole in it next to the glowing oven ignitor; also seems to be a short life for such an expensive part, as my 40 year old tappan uses the same ignitor and has no such issues with holes. I think it is because the bluestar ignitor is placed very close to the burner tube...just something to keep an eye on as your stove ages. Other than these issues and intermittent rattling from the convection fan (which i think also was fixed in newer models), my oven does bake nicely.

You’re welcome Jesse
I’ll keep an eye on the burner tube as my range gets older in the event an issue arises.

I have a problem with my brand new blue star wall oven. Condensation out the top on the cabinets. It just seems to coming out from between the oven and the cabinet. It’s going to ruin my new cabinets. I am calling Blue Star on Monday. I hope they are as responsive!! (Pic — I had just wiped off.) It seems to stop when oven gets to temp but there is a lot of moisture!
