Frequently Asked Questions

Q: What refrigerators is this PTC start relay compatible with?

A: This PTC start relay and overload protector is designed to fit a wide variety of mini refrigerators, compact coolers, and air conditioning compressors rated at 1/6HP (R600A/125W). It is available in both 1-pin and 2-pin configurations to match different compressor sockets. Always verify your compressor's pin layout and resistance rating before ordering.

Q: How do I know if I need to replace my refrigerator's start relay?

A: Common signs that your start relay may need replacement include the refrigerator not cooling, the compressor clicking on and off repeatedly, or the appliance not starting at all. You can test the existing relay by shaking it — a rattling sound often indicates a faulty relay that needs to be swapped out.

Q: Is this relay easy to install yourself?

A: Yes! The PTC start relay is designed for straightforward DIY installation. Simply unplug your refrigerator, locate the compressor, remove the old relay by pulling it off the compressor terminals, and snap the new one into place. Always ensure the power is completely disconnected before beginning any repair work.

Q: What is the difference between the 1-pin and 2-pin versions?

A: The pin count refers to the number of electrical terminals on the relay that connect to your compressor. Different compressor models use different socket configurations. Check your existing relay or your appliance's service manual to confirm whether you need a 1-pin or 2-pin replacement before purchasing.
