Product review (2 stars): Works great now.
I bought this and a new limit switch to address the actuator getting stuck sometimes.

This new one made it even worse-- the plastic piece that gets pushed in to depress the limit switch was misaligned with where it needs to be for my refrigerator. As a result, it would have a lot of friction against another plastic surface and would get stuck.

I ended up being able to address it by taking a Dremel to the plastic piece on the back side of this pad to shave down the areas that were rubbing against the plastic in my refrigerator. Works great now.
