  • Consult the appliance's service manual for specific guidance

FAQ

This 3-in-1 hard start kit is designed for 115VAC refrigeration compressors ranging from 1/12 HP to 1/2 HP. It is commonly used to restore functionality in residential refrigerators, freezers, and dehumidifiers that are struggling to start.
The RCO210 is rated for 110-125VAC systems with a maximum continuous RLA (Rated Load Amps) of 13.3A. The internal capacitor provides a capacitance range of 243 to 292 MFD to assist the compressor during startup.
If your refrigerator or freezer compressor is clicking, humming, or attempting to start but failing to run, the original relay or overload may have failed. This kit replaces the existing relay, overload, and start capacitor, providing the necessary torque boost to help older or unbalanced compressors cycle on.
The unit features three color-coded wires for easy identification: the Black wire connects to the Common (C) terminal, the White wire connects to the Start (S) terminal, and the Red wire connects to the Run (R) terminal on the compressor.
Installation is straightforward and typically takes 15 to 30 minutes. It uses standard quick-connect terminals. Ensure the power to the appliance is completely disconnected before beginning, and verify the compressor terminals are clean and free of corrosion before attaching the new leads.
