Rotom HVAC Dual Run Capacitor 36-353R3744, 35/3MFD 370/440V Round

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Compressor hums but fails to start or trips on thermal overload
• Condenser fan motor struggles to start or runs at reduced speed
• HVAC system short-cycles or shuts off shortly after starting
• Capacitor body visibly bulged, leaking, or reads out-of-tolerance on a capacitance meter

Check Before Replacing

• Test both capacitance values (35MFD and 3MFD) separately with a dedicated capacitor tester — both must be within ±5% tolerance
• Inspect the contactor for pitting or burning — a worn contactor is a common co-failure with a capacitor
• Verify the compressor and fan motor windings are not open or shorted before condemning the capacitor
• Confirm the electrical supply voltage and wiring connections are correct before replacing any component
