refigator doesn't always start

This unit will run fine for sevral days to weeks. Then it will shut down & not restart. If I tap on the thermostat it restarts. My question is can the thermostat be cleaned, repaired or do I have to change it. Thank You

Remove screws from cold control (1101163) Tap on it to see if the fridg turns off. If you tap on the control mounted, you might be vibrating the defrost timer.

Can you be more specific on the problem?
