상품 특징

• PTC compressor start relay replacement part for 110V refrigerator/freezer compressor start circuits; Part No. 4R7MC1. Helps restore normal compressor starting by providing the PTC start function when the old relay is worn, burnt, or has a loose connection. Aftermarket repair part—confirm the marking and physical interface match your existing relay before ordering.
• Install tips: Disconnect power before service. Access the compressor compartment, remove the terminal cover, then pull off the existing start relay and push the 4R7MC1 relay onto the compressor terminals firmly. Check for cracked housing, heat damage, or burnt terminals and replace any damaged terminal cover/connector. Do not force-fit—confirm the terminal layout matches your compressor and the relay seats fully.
• Fitment verification (required): This part number is commonly sold as a refrigerator/freezer compressor PTC starter relay. Confirm fitment by matching OE/marking 4R7MC1 on your old relay and comparing the terminal arrangement and size. If you are sourcing a vehicle relay, verify using your vehicle manual/parts catalog—do not rely on name similarity alone.
• Troubleshooting & related parts: A failed start relay may cause clicking, compressor not starting, intermittent cooling, or repeated start attempts. If the relay shows heat damage, it is common to inspect/replace the compressor overload protector at the same time, since both sit in the same compressor start device area. Always verify compressor condition and wiring if symptoms continue.
