My craftsman 1/2 hp garage dood does not close when it's cold out (with either a push on the remote or a single push from the wall). I have to hold the wall button in until it's completely down. When I do push either the wall button or the remote button the light flashes a bunch of times and won't shut. The lights on the sensors are a solid green
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.
No each manufacturer uses a different code that is built into the keypad.
Make sure the battery is good and then locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this button and then walk over to the keypad and key in a 4 digit code and press enter.
This button toggles off and on by holding in for 3 seconds.
If your opener doesn't have safety sensors in the doorway this keypad will not work with it.
Replacement of both springs is recommended.
