Craftsman / Chamberlain Remote Garage Door Opener Keypad ~ Cold Weather Operation Failure Repair

In this video we will go over repairing an issue where your Craftsman, or Chamberlain, remote garage door opener keypad begins to fail only in colder weather (working fine in warmer weather). The problem is that the change in temperature exacerbates tiny fractures in the solder of the circuit board inside the keypad housing. As it gets cold the contraction of the metal results in an interruption of the electric flow of the internal circuitry.

The remote keypad illustrated is the Sears Craftsman 139.53754-01 in 315Mhz. But this problem, and the repair approach, could apply to any Craftsman remote keypad of similar cosmetic design. It would also apply to Chamberlain remote keypads, the original OEM supplier to Sears for Craftsman remote keypads, such as the model 940EV.
