How do I know if my run capacitor is bad?

The motor it powers (fan or blower) won't start, hums but doesn't spin, runs slow, or trips on overload. We bench-test these free at the counter — bring it in.

Can I use a higher MFD rating?

No. Match MFD exactly to the motor's data plate. Higher MFD over-amps the windings and shortens motor life. Voltage rating can go UP (440V replaces 370V) but never down.

Does shape (oval vs round) matter?

Electrically no — same value works in either shape. Fitment in your cap bracket might. Bring the old one in and we'll match the form factor.

Do I need to discharge it before removing?

Yes — even an "off" cap holds 240V+ that bites hard. Short the terminals with an insulated screwdriver for 5 seconds before disconnecting.

Pro tip

Bring the old cap in — we bench-test it free at the counter, and you'll know in two minutes whether it actually failed. Match the MFD exactly; voltage can go up (440V replaces 370V) but never down.

Symptoms of failure

AC hums but the fan and compressor will not start
Outdoor fan only starts if you push it with a stick
Compressor tries to start, clicks, then trips the breaker
System short-cycles or runs warm on a hot afternoon
The capacitor top is domed, split, or leaking oil
Unit worked this morning and quit in the heat of the day

Seeing these does not always mean this part is the culprit. Bring the old one in and we will meter it at the counter, free, before you buy.

If your AC won’t start, hums but doesn’t kick on, or runs but won’t cool, a bad capacitor is the most common cause. This 35 MFD round cap powers a single motor — compressor or condenser fan. Replace when the motor hums but won’t kick on.

Replaces: Universal — matches by MFD and voltage.

Fits: Fits most residential HVAC systems using this value. Bring your old cap or model number — we match at the counter.

Installing it yourself

Difficulty 1/5Typical time 15-20 minutes

Kill power at the disconnect and confirm 0V. A capacitor stores a lethal charge with the power off.
Discharge it: bridge the terminals with an insulated-handle screwdriver, or a 20k ohm resistor, then confirm 0V with a meter.
Photograph the wiring before you pull a single wire. HERM, FAN and C are not interchangeable.
Loosen the mounting strap and lift the old capacitor out.
Match MFD exactly. Voltage may go up (370V to 440V) but never down.
Land the wires on the same terminals, strap it down, restore power.
Never handle a swollen or leaking capacitor by the terminals - bring it in and we will dispose of it.

Power off at the disconnect first, every time. Not sure partway through? Bring it to the counter and we will walk it with you.
