The three usual causes: dusty condenser coils (Fallbrook rural properties with agricultural activity nearby see faster dust accumulation than suburban homes), a failing evaporator fan motor, or a failing defrost system.
Dusty coils are a specific Fallbrook consideration. Bonsall grove properties, De Luz ranch properties, and rural Fallbrook homes near agricultural land see fine dust accumulation on refrigerator condensers faster than typical suburban homes. Combined with the summer heat load, coil cleaning is preventive maintenance that pays for itself in extended compressor life.
A coil cleaning takes 15 minutes and costs $95 with the diagnostic fee waived. A replacement compressor costs $450 to $800.
