Rotom HVAC Run Capacitor 36-20R3744, Replaces Failed 20 MFD 370/440V Round Capacitors

Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Motor hums but does not start or starts very slowly
• Motor overheats during normal operation
• Motor runs intermittently or shuts off unexpectedly
• Fan or blower fails to reach normal operating speed
• Capacitor case is visibly swollen, bulging or leaking

Check Before Replacing

• Test the capacitor with a capacitance meter — compare the reading against the tolerance printed on the original label. A reading outside tolerance confirms failure; a reading within tolerance suggests another cause.
• Confirm the original is a single-value 20 MFD motor-run capacitor — do not substitute a 20/5 MFD dual-run capacitor without intentional rewiring of both sections.
• Verify the original voltage rating — a 440V or 370/440V replacement is acceptable for a 370V application; a 370V-only capacitor must not replace a 440V-rated application.
• Confirm the round case dimensions (1.78 in diameter × 3.15 in height) and terminal arrangement fit the available mounting space before ordering.
