Does it have the safety electric eyes that aren't aligned?

The following comment isn't directed toward you pesonally. These forums can be an indicator of product quality. I think if a person reads them and consistently sees problems with the same product over and over and over then I think one can assume that there is a significant problem with said product. In this case questions about problems with Sears Garage Door Openers are posted constantly. They must be the most unreliable machines ever built. I'm sure some readers will testify that they have one that works perfectly. There is no doubt that some of them do work good. My point is that the failure rate must be much higher than average to make so many people post their problems here. Do a search....there are literally dozens and dozens of posts about these Sears Garage Door Openers. My advice is to get a Genie.

I bought two belt drive units from Sears. Mostly b/c they were supposed to be the quietest units on the market; I have a bedroom over the garage so this was an important feature for me.

Well, when its damp outside both of them squeak like all hell. I have to get up on a ladder and squirt silicone spray into the drive mechanism to make them shut up. I called Sears 3x's and the Sears installer came out twice. Each blamed the other and at the end my warranty expired before anything was done.

I would never buy another Sears garage door opener. I half want my existing units to fall out of the ceiling so my wife doesn't yell at me for buying new Genies.

Lightning and other power surges love to kill garage door openers. I would buy a surge strip and mount it on the ceiling next to where the opener plugs in and it will last a lot longer.

When I try to open the garage door the gdo makes a humming noise and the gdo light comes on but the door doesn't open. Then there is a light that flashes on the unit 5 times, then a pause? Any clue since the former owner never left the owners manual? THANKS PATTY

I wonder if the door isn't locked. You could also try pulling the release rope to see if the opener runs on it's own. Typically you will see a notch where the rope ties on to pull the lever into.

I PULLED THE RELEASE CORD TO GET IT CLOSED.

So what you are saying that the door itself functions normal, and one point the door went up with the opener. But instead of the opener coming down, you get the light flash, correct? My Chamberlain book says that 5 flashes indicate an RPM sensor failure, and the suggestion is to first unplug the opener and to try again. If you would like to get a manual, Sear's website has them available. The model # tag if not visible from the outside may be under the light cover.

You WILL get a lot more help on the Home Repairs forum.
These GDO q's come up all the time and there are one
or two experts over there who help a lot.

Don, over there, has kept my Sears GDO alive for over
10 years with periodic adjustments of lift and force
and greasing of the drive gear.

One reasons a lot of Sears GDOs fail is that so darn
many are sold!

Sears Craftsman garage door openers fail because they are cheaply made and horribly designed. They use marginal components that can't take any strain without failing. In fact they fail all on their own without any reason. My advice is to chunk the Sears Craftsman garage door opener and buy a Genie and be done with it for good. Just search this forum if you don't believe me. There are more Craftsman garage door opener failure questions than anything else by far. There are hundreds of posts about these pieces of junk. It isn't because they sell that many more either. In all of my life I have never seen anything with such a high failure rate....except maybe the Chevrolet Vega.
