My refrigerator was dripping water from the upper freezer into the lower section, caused by the drain passage freezing up every couple weeks. This required repeated emptying & "defrosting" of the freezer (Just like in the "good old days").

I found my frig. schematic inside near the timer device, & did some research on the web. I'm a technician by trade, so understanding what was happening was easy enough & there are only 3 items in the defrost circuit, 1] the heater I was able to verify OK by an Ohm meter test, 2] the timer I could see the gears spinning once the cover was removed, and 3] the thermal switch (aka defrost thermostat). My frequent defrost excercises made me familiar with access to the back of the freezer where the thermostat lives. It was wired into a connector, but I simply snipped the wires at a convenient spot (leaving the connector intact) & wire-nut spliced the new thermostat into the original wires. No muss. No fuss. Frig. works great now & the part cost was about 1/6th of local supplier, & I wouldn't even guess what a service call would have been. Do it yourself. It's easy.

I installed this in neighbors fridge and it worked just fine. The old one popped up and was not completely defrosting.

I was having some issues with my fridge. I was having liquid entering from the freezer to the fridge, once I replaced the defroster so far it has corrected this issue,

Thank you,
