FAQs

Q: Where can I find the wiring diagram for my Frigidaire refrigerator?
A: The wiring diagram is often located inside the refrigerator, behind the control panel, or on the back of the unit. You can also search online using your refrigerator’s model number.

Q: What does the overload protector do?
A: The overload protector safeguards the compressor from overheating by cutting off the power supply when the motor draws excessive current.

Q: What is the function of the start relay?
A: The start relay provides a temporary boost of current to the compressor motor to help it start.

Q: Can I replace the compressor myself?
A: Replacing the compressor requires specialized tools, knowledge of refrigerant handling, and EPA certification. It is generally recommended to hire a qualified technician.

Q: What are common signs of a failing compressor?
A: Common signs include the refrigerator not cooling, the compressor running constantly, unusual noises, and the compressor not starting at all.
