I have W9RXXMFWQ00 that isn't working anymore unless I hit it, so I'm assuming the thermostat is broken.

A replacement thermostat is 150$ so that is out of the question

I was wondering if anyone ever used a temperature relay such as Siemens 3RS1 or something like that to act as a thermostat?

I see no reason why a device such as the Siemens 3RS1 could not be adapted to control a refrigerator. I'm assuming you have one on hand as the price of one of these is close to the $150 that you are saying is out of the question.

Keep in mind that this device has no built-in thermometer, so you'll need to add an appropriate one of your own. Also be aware of the output capacity so that you don't damage it by switching the compressor on and off.
