What is the model number of the refrigerator?
Possible cause could be a faulty defrost thermostat (or thermistor - may depend on model).
The defrost thermostat is used to signal the end of the defrost cycle. The defrost cycle occurs approx. once every 10 hours so this may be about right for you having to reset it twice per day.
During the defrost cycle, both the compressor and the evap fan are turned off. The temperature in the freezer compartment is allowed to rise to melt the ice and the defrost heater is turned on to help speed up the melting the ice build up on the evaporator coils. With the evap fan turned off the refrigerator temp will also go up as no cold air is being blown into the compartment from the freezer. When the defrost thermostat’s set operating temperature is reached it signals the control board to turn off the heater and to restart the compressor and evap fan to cool things back down to the set temps. When the freezer temp reaches the thermostat’s release temperature, it releases in readiness for the next defrost cycle ~10 hours later. Normally a defrost cycle lasts about 20-25 minutes.
If it is a thermistor its resistance value will change with the temperature and the control board then knows what to do. The principle is the same as for a thermostat
I realize that you said the the compressor noise is ongoing but you said that you only thought that it was ;-) Turning off the power “resets” the control board but the defrost cycle will kick in again 10 hours later.
Search online for (insert full model number) parts and select either the partselect.com or searspartsdirect.com link to view the parts for the refrigerator. When you have the parts diagram webpage, search for tech sheet or mini manual in the search parts box for that model. If there is a number listed (with GE it may start with 31-) search online using the part number only to hopefully find download links for the tech sheet or mini manual that will show you how to get into the diagnostics etc.
