Sears Craftsman Garage Door Premium Control Console Failure in Cold Weather

Just installed a new Sears Craftsman garage door opener (Model 53993) 3 weeks ago. Now that the weather is cold (10F or less) in my garage, the Premium Control Console inside the garage is failing. The little green bulb light is mostly off. If I press the "big" button to open/close the door the light will come on momentarily, but the door won't fully open/close or if it does close then it will open part way after 30 seconds or more.

I called Sears services, they would send a technician out to look at it but charge me the $65 service call fee if it was an installation problem on my part. I deferred having a service guy come out and bought a new Premium Control Console for the wall for $20. Same problem.

If I take the snap off the "big" button (the top part where the green bulb shows through), then the green bulb lights up and everything works when I push the little small pad/button that actually causes the signal to be sent. This implies the wire connections are all tight and fine. Of course I don't want to leave leave the button cap off (presumably until it warms up).

Anyone have similar experiences?

Anyone know of a solution?

    I have the same model, just had a serious cold snap last night and it's behaving in the same fashion. The overhead light blinks on & off a series of times and it won't open without holding the wall button down for the duration of the open task. I've had the thing a year or so now, and this is the first I've seen of this behavior. The motor strains a bit while forcing the motor to go up, I wonder if the temperature & the resulting viscosity of the screw drive lubricant is triggering the sensor to think the door is being obstructed? It's certainly not an installation issue, as I've had a year of flawless operation out of the door.

Premium Control Console has power to it. Green

Your control may be defective. You can check this by removing the two wires to it and shorting them together momentarily. The door should operate.

Craftsman Garage Opener (Unit run front & back only for 2 second)

Double check to make sure the sensors are wired correctly. The 2 solid white wires go to terminal 2 and the wires with black stripes go to terminal 3. If the wiring is correct then you possibly have a bad RPM sensor. The RPM sensor is a small circuit board just in front of the motor.

Garage door opener will not close in cold weather

The are two knobs on the back of the opener. They are force settings. One is the upforce and the other is downforce. Turn both knobs to "5" and try. This should take care of the problem. They come from the factory at 1 or 2 and when it gets cold it takes a little more force to cloce the door.

Garage door opener

You can turn up the up and down force on the motor head to give the unit more power. During colder weather the unit needs more power. Afterward do a 2x4 safety reversal test. thanks, BB

Craftsman Garage Door Opener

From the manual:
Security+Light Feature: Lights will also turn on when someone walks through the open garage door. With a Premium Control Console, this feature may be turned off as follows: With the opener lights off, press and hold the light button for 10 seconds, until the light goes on and off again. To restore this feature, start with the opener lights on, then press and hold the light button for 10 seconds until the light goes off, then on again.
