Question about Refrigerators
I have turned the thermostat all the way cold. I have removed the cover and by-passed the thermostat. No luck. The evaporator and condenser fans are both running. The compressor is not kicking in consistently. I did hear it kick in after I moved it around and knocked on the relays around the compressor. Is there a replacement relay, sensor or capacitor on the compressor? A manual with schematics and exploded views would be helpful.
It is possible it is low on refrigerant!
Kicking and knocking parts wont help here.................there is a low pressure swith in the line and when the gas gets low ( a leak ) it protects the compressor by shutting down!
Since the pressure's fluctuate in a system when it is on and then off; it will cycle.

If the thermostat has been bypassed it sounds like lack of refrigerant gas in the system. The level cant be checked visually, it will need to be checked by an engineer with pressure gauges.

refrigerator is not cooling properly it can be due to a defrost timer, which is
causing the fridge to go into defrost cycle. Usually it takes 45-60 minutes for
refrigerator to come out of defrost cycle. If the timer
is bad then it will not come out of defrost cycle and
can result in this kind of issues. It can also occur due to a bad defrost thermostat,
it allows current to pass through it at temperatures of 20 to 30 degrees
Fahrenheit and prevents current from passing through it at 40 to 60 degrees.
This is difficult to test, though, because it takes a prolonged, very-cold
temperature to turn it on. The defrost thermostat is
snapped onto the top portion of the evaporator. The thermostat sends
temperature information to the processor. The defrost heater must be replaced
when replacing the thermostat.
1. Remove the lower fan duct work from the evaporator cover.
2. Remove the 1/4-in. evaporator cover screws and remove the evaporator cover.
3. Disconnect the defrost thermostat wiring connector.
4. Remove the defrost thermostat from the evaporator.
