Frequently Asked Questions

A: A PTC (Positive Temperature Coefficient) starter relay is a small but critical component that helps start the compressor motor in your refrigerator or freezer.

Q: How do I know if my starter relay needs to be replaced?

A: Common signs of a faulty starter relay include the refrigerator not cooling, the compressor clicking on and off repeatedly, or the compressor not starting at all. You can also shake the old relay — if you hear a rattling sound from inside, it's typically a sign the relay has failed and needs to be replaced.

A: Yes! This PTC starter relay is designed for straightforward DIY installation. Simply unplug your appliance, locate the compressor starter relay, remove the old one, and plug in the new relay in the same position. No special tools are required, making it an ideal repair for handy homeowners.
