Question about Sears Craftsman LiftMaster Chamberlain Garage Door Opener Wireless Keypad Model 976LM Security+

1 Answer

Remote will not open or close door when temperature is cold.

I have a single door 1/2 HP Craftsman model #139.53910D. When the temperature is in the 30's and below the remote will not open or close the door. The unit works fine at these times using the hard wired button inside the garage. As soon as the temperature warms the remote again works perfectly. I'd really appreciate being able to correct this problem. Thanks.

Bill

If this is an outside remote the best you could do is maybe put someting to insulate the remote if it is in your car don't leave it on the visor put it in the glove box or maybe the center console it is obvious that expansion/contraction physics are playing a part

Make sure the brackets for the sensors are tight and the small light on the sensors is not blinking ever so slightly. You also might try shading the sensor so that the sun is not shining directly into the lens.

If the main light flashes 10 times when you try to close the door it is a sensor problem. Make sure they are not flickering ever so slightly and that they are not loose on their brackets. Tweak them a little bit.

When the temperature drops below 30 degrees F my garage door opener will not close the door. I tried adjusting the downforce but it still does not close. Craftsman 41A4315-7C


Put the down force adjustment back where it was as it affects the safety reversing. If the main light flashes 10 times when you try to close the door it is a door sensor problem. Make sure they are pointed at one another and the small light on each one is lit and not flickering. Tweak them a bit if necessary. It could be an electronic component that is sensitive to cold and quits when the temperature drops. This is not uncommon.

Your door sensors are either bad or need simply to be aligned. They must be pointed at one another to work properly. Each of them has a small light that will be lit when they are pointed correctly.

I have a craftsman garage door opener (1/2 hp) won't close proper


Check your door sensors. They have probably been bumped. Tweak them until they are pointed at one another and the small light on each one is lit and not blinking.

One of the remotes manages both doors instead of just one


don't use that one! Seriously, you need to wipe out all codes and reprogram your keypad and remotes.
