Carrier 17122000002495 Control Board 321702-401 This kit provides the necessary

This kit provides the necessary hardware to restore proper fluid level control and containment within the pressure vessel

but we recommend using a multimeter to verify voltage and ground continuity to prevent damage to the new circuitry

a 440V capacitor can be used as a substitute as long as the 15 MFD capacitance and physical oval footprint match

Correct installation requires ensuring the groove is free of debris and lightly lubricated with system-compatible oil to prevent twisting or binding during assembly

Reliable 120V Operation: Designed for high-duty cycles to prevent premature failure during extreme cold-weather demands
