✅ Cross Reference Information

Common Symptoms

• Motor hums without starting
• HVAC condenser operates intermittently or does not cool

Check Before Replacing

• Compare the installed capacitor label with the required 30/5 µF and 370/440 VAC ratings before ordering.
• Have a qualified technician disconnect power and test both capacitor sections with a capacitance meter.
• Inspect the capacitor for bulging, leakage, burn marks, or damaged terminals; visual inspection alone does not confirm electrical failure.
• Check physical clearance and mounting space against the approximately 1.97-inch diameter by 4.16-inch height dimensions.
