Freezer would not defrost properly, Fan would quite working and fridgew would stop cooling

I had the repair man out 5 times. 3 new fans and 2 defrost timers and my refridge still would not work. Spent five minutes on the Parts Select site and found the problem. Ordered the part shich showed up in two days. Steps involved in replacing are as follows. 1)Remove back cover in freezer compartment. 2)locate old Thermostat on top of freezer coil. 3) Mine must have been replaced once before becouse it had cripm connectors ofn the wires just before the thermastate, so cut the wires at the crimp. trimmed the wires on the new part and crimped it the existing wires. 4) place the new thermostat on the Coil and started it back up again. Has worked great for over a week and a half. So nice to have ice again.
