How to fix your fridge when it's not cooling

You see the wires but not that thermostat because it failed is why the ice built up until blocking air into reefer compartment.

Use a heat gun or hair dryer to quickly eliminate all the ice but be careful to keep it moving and in no one place for long as the heat can melt plastic walls or boil refrigerant.

This is the new part that clips right onto evaporator coil place it in same spot as the bad one.

A bad part and you can clearly see it is separated if you advance defrost timer and defrost element has continuity but not heating up then replace thermostat once you determine it's not timer either
