Hello Pat Remus, Chamberlain... Has been around for a very long time ... type of door... presumed to be OVER-HEAD... Operation issues .... (were okay (?) sudden fialure is likely a BROKEN BALANCE SPRING EASY to check... CAUTION: doors can be EXTREMELY heavy. FROM the closed position... (to avoid a door crash)... You should be able to disconnect your GARAGE opener... and feel the well balanced motion rom the full open to FULL closed. If you hear any chatter of springs. THEY need to be lubed (often)... ELSE That "chatter" will turn into "SHATTER"... Those springs will break... and need to be replaced ( pretty RISKY job best done by a SERVICE company )... If the door is quiet & well balanced... Then it is time to check the "travel" contacts... and adjust them the the proper HEIGHT is achieved. >> READ THE MANUAL... OWNERS (model??) No exact matches found Try these results Hope this helps...

Do you have a security system in your home? Sometimes the door shut sensors get out of alignment and the door strikes the sensor. This is the exact same problem I had with my door.

There should be a battery on your wall unit that needs replacement. God bless your efforts.

no, chamberlain openers require chamberlain, liftmaster, or craftsman safety eyes

You may need to replace the battery in the remote control. Most usually these will be double A ones. You may have to reprogram it when you try it again. You should be able to get the information on Google by typing in the make of the inside unit in your garage. Your remote may have this info on it as well. You should be able to pull up instruction on how to reprogram your unit.

could be that the remote operation or cycle operation needs reprogramming as it indicates that the program has a corruption in it and the action is lost by that corruption follow the user manual and do the reprogram sequence

Yes you can do that just code the doors the same.

Check that the wheels and bearings are turning freely and that the door is not cocking to one side when closing. If the wheels are catching because of bad bearings, because the tracks are out of true or because the door is not staying straight in the tracks, the motor thinks that the door is hitting a car or a person and reverses. One thing to try: disengage the motor and try moving the door through the full traverse. Most automatic doors have a pull-cord that disengages the door from the motor. CAUTION: You may need a friend to help with the door, because it could be surprisingly heavy,.

I just installed this opener 1 week ago and the same thing happened. I remembered there is a "Belt Cap Retainer" that covers the motor sprocket and is held on with 2 screws. I removed the cover and the squeaking stopped. There is a small dab of grease (silicone?) that the instructions did not mention. I spread the grease around the cover next to were the belt travels and put the cover back on careful not to over tighten the screws. No more squeak!

Unplug, let it sit for a minute and plug back in. Ours does that when power is interrupted.

Seems like you either have your photo cells out of alignment or disconnect from operator or a short in the photo cells wires.... make sure the you can see the green LED light on one and a amber/red on the other at the same time with no flashing or flickering. The green represents power supply to units and other color represents alignment, both are a must! so make sure you see them on solid without blinking or flickering.

It could be as simple as a drive motor force adjustment... (you will have to get out the instruction manual) Most likely your balance spring... one has failed look over your springs very carefully... if one has shattered your counter-weigh is only lifting HALF the weight of your door. Most garage doors need to be fairly NEUTRALLY BALANCED for the best, longest and reliable use. Routine lubrication of the springs can add decades of useful life to your springs... CHATTERING Springs make a lot of noise and will soon shatter (break). Sears makes house calls... but they try to sell openers... you don't need. https://www.bing.com/search?q=overhead%20garage%20door%20service&qs=n&form=QBRE&pq=overhead%20garage%20door%20service&sc=8-28&sp=-1&sk=&cvid=10E42AB45BFC41CC8E82D92DA893AB36 Sears Online In Store Shopping Appliances Clothing More
