35/5 uF 370V Dual Run Capacitor — OEM HVAC Replacement
This 35/5 uF 370V dual run capacitor is a direct OEM replacement for AC compressors and condenser fan motors. Dual run capacitors power both the compressor and fan motor from a single unit, making them the most common capacitor type in residential central air conditioning systems. If your AC is not cooling, making a humming noise, or the fan is not spinning, a failed run capacitor is one of the most common causes.

Frequently Asked Questions
Common signs of a failed run capacitor: AC unit hums but doesn't start, fan spins slowly or not at all, AC trips the breaker, or the unit runs but doesn't cool. Use a multimeter with capacitance measurement to test — a reading more than 10% below the rated value indicates a failed capacitor.
Yes. A 440V capacitor can replace a 370V capacitor — the higher voltage rating is safe and will not damage the system. The capacitance (uF) must match exactly. Never use a lower voltage rating than specified.
You'll need a screwdriver to access the disconnect box, needle-nose pliers to remove the terminals, and a multimeter to test the old and new capacitor. Always discharge the old capacitor before handling — capacitors can hold a dangerous charge even when power is off.
