freezer and refrigerator too warm

I put the refrigerator and saw that the fan wasn't working so I change the fan and the problem still the same. I order a timer and thermostat and change them, nothing change so I order the capacitor and when I remove it I saw that the relay swith was burn out so I order a switch and evarything is ok.
The problem when the fan broke the compressor overheat and burn the swich.
I learn a lot and still saving money over these repair guy.

Thanks
