Frequently Asked Questions

Q: How do I know which pin configuration (1-pin, 2-pin, 3-pin, or 4-pin) PTC starter relay I need for my refrigerator?

A: Check the existing starter relay on your refrigerator compressor or consult your appliance's user manual. The number of pins on your current relay must match the replacement. If you're unsure, noting your refrigerator's model number and looking it up in the service documentation is the most reliable approach.

Q: What does the thermal overload protector do and why is it important?

A: The thermal overload protector is a safety device attached to the compressor. It monitors the current drawn by the compressor motor and automatically cuts power if the motor draws too much current, preventing overheating and potential appliance damage. It is a critical component for long-term appliance reliability.

Q: Is this PTC starter relay compatible with R600A refrigerant compressors?

A: Yes. The 1/6HP (125W) overload protector variant is specifically noted as compatible with R600A refrigerant compressors, which are common in many modern mini fridges and coolers. Please confirm the wattage and pin count match your unit before purchasing.

Q: Can this relay be used for air conditioners as well?

A: Yes. This starter relay is suitable for air conditioner compressors and other electrical motor applications requiring compressor protection, provided the specifications (resistance, pin count, and HP rating) match your equipment's requirements.
