Frequently Asked Questions
Q: What does the QP3-15/C PTC starter relay do in a refrigerator?
A: The QP3-15/C PTC starter relay is a small but critical component that helps the compressor motor start up. It uses a Positive Temperature Coefficient (PTC) resistor that briefly allows a high current to flow to start the motor, then limits current once the compressor is running. The integrated overload protector monitors the compressor and cuts power if it detects excessive current or temperature, safeguarding your appliance from damage.
Q: How do I know if my QP3-15/C relay needs replacing?
A: Common signs that your PTC starter relay or overload protector needs replacing include: the refrigerator compressor not starting, the fridge not cooling, a clicking or buzzing noise from the back of the appliance, or the compressor starting and stopping frequently. Shaking the old relay — if you hear a rattling sound, it's likely failed and needs replacement.
Q: Is this relay compatible with refrigerator brands other than Frestec?
A: This QP3-15/C unit is listed as a universal replacement and is specifically noted as compatible with Frestec refrigerators and freezers. Always verify the model number of your existing relay before purchasing to ensure compatibility with your specific appliance make and model.
