HT21 - Overview

I applied some tips learned by reading other reviews. So before I started I grabbed my trusty vise grip pliers and a small screw driver. I locked onto the switch actuator, the part that the refrigerator door pushes in, with the vise grips and pulled on it just hard enough to get the screw driver inserted in the right side to push in the catch clip so the switch could be pulled out further each time the catch clip was depressed to the next detent. Then I used the screw driver on the left site to encourage the switch past the detents on the left and very quickly the switch was out of the mount. The wires from the refrigerator pulled out with the old switch. I unplugged the old switch from the wires and plugged in the new switch and shoved the new switch back into the mount, wiggled it a couple of times to make sure it was secure and the job was done. Once I applied the vise gripes at first, the whole job took less than a minute.

Poped out with screwdriver the old swithch and unplugged the two wires. Plugged in the wires to the new swithch and pushed it back in the hole where the old switch was before.

While the switch did last for 9 years, the design is poor due to the failure mode. The failure should be to fail off or not able to turn on the lights which would be inconvenient but would not warm the refrigerator contents. Arcing at the contacts eventually caused the switch to "weld" closed. It is not obvious that this is occurring so it took some time to recognize why the temp inside the ref was high while the freezer was OK. Replacing the switch was easy once it was recognized as the problem. All that was required to replace the switch was to remove the screws holding a fiber cover and then pulling off the aluminum cap which covered the switches. Unplug the switch an squeeze the keeper on the switch to release it and pull down. Pop the replacement switch in place and plug the wires harness back in. All in all it took much less time to replace than it has to write this up. T Pope
