This OEM dual run capacitor (part #1177750) is the genuine replacement for ICP/Tempstar/Heil model WJA360000KTP0A2. A dual run capacitor provides the constant phase shift the compressor and condenser fan motor need to start and run efficiently. The 70 MFD section feeds the compressor (HERM terminal) while the 10 MFD section drives the condenser fan motor (FAN terminal), both rated at 370 volts. When a capacitor weakens or fails, the compressor and fan draw excessive current and overheat — the most common cause of a no-cooling call. Typical failure symptoms include a humming compressor that won't start, a condenser fan that needs a manual spin to turn, a bulged or leaking can, and intermittent breaker trips on hot days.

Directly fits ICP, Tempstar, Heil, Comfortmaker, and Arcoaire condensing units using OEM part 1177750, including model WJA360000KTP0A2. Always confirm the MFD rating and voltage on your existing capacitor before ordering — a 370V capacitor may also be used to replace a 440V unit of the same MFD, but never the reverse.
