MyQ opener model 940ESTD will not close the door in cold weather.

I live in Wisconsin and it obviously gets cold. The first winter it had no problems closing in cold weather. The net winter it started having problems only when temps dropped below 0. Now this years anything below about 20 degrees and the door will not go down. I have to hold down the wall unit button until the door closes each time we use the door. This completely defeats the purpose of having a garage door opener.

I was contacted by Chamberlain Technical Support and after trying a few different setup options, they sent me a new travel module which only took about 15 minutes to install. They also sent all the setup information I needed to complete the installation and setup. The door now works perfectly. 

Thanks for your efforts,

Dean, thanks for waiting. LiftMaster/Chamberlain operators are designed to work in temperatures ranging from -4 to 149 degrees Fahrenheit.

Based on the description you've given, it seems like a safety sensor issue.

If the sensors are correctly aligned, it’s possible for condensation or frost to form on the safety sensors and make your door opener seem like it is inoperable. A quick wipe with a dry cloth across the two glass boxes, found on each side of your garage door, should solve the problem.

If this does not do the trick, please send me another note and we'll get it figured out. Thanks, Lauren

No luck. Today's outside temps was in the mid 20s. Inside the garage a bit warmer.

I cleaned sensors. Same problem. I checked alignment with a laser level. No problem with alignment. I sprayed garage door lubricant on the rollers and track. Same problem. 

Without a tension adjustment I do not see how a door can accommodate the cold. Seems like a very short sighted design to me.

I noticed the chain was hanging a bit so I adjusted that (tightened), No change. Probably should have returned this unit when I first purchased. None of the "fancy" features such as connecting to our phones or home Wifi has ever worked. It won't program to my 2005 Tundra when I can program my Tundra to my other garage opener with no problem. This opener has been nothing but problems since it was installed.

Today the temps were in the 20s. We just returned from a trip and the door would not go down. Your technical team sent me some instructions on setting the force which has turned out to be useless. I cycle through the force adjustment as described below. It seemed to work through the adjustment process, but when I tried the down operation after the adjustment, once again the door stopped half way down and went back up with the light flashing. 

There is something WRONG with this opener and something really WRONG with the tension control. 

To program the forces separately without resetting the travel:
1. Press and release the yellow learn button twice. The LED next to it and one of the UP or DOWN arrows will blink.
2, Press and release the blinking arrow and the unit will operate in that direction.
Once the operation completes, the opposite arrow will begin blinking.
3. Press and release the blinking arrow and the unit will operate again.
Once the operation completes, both arrows and the learn LED should be out. This completes force
programming.
