Can a 440V capacitor replace my 370V one?

Yes. A 440V rating covers 370V service, but a 370V part should not replace a 440V one.

It fits round mounting brackets sized for a standard dual-run can. Check that your old capacitor is round, not oval.

What do the C, HERM and FAN terminals mean?

C is common, HERM feeds the compressor and FAN feeds the fan motor. Wire them to match the old capacitor.

Does it work on Goodman or Trane units?

It is built as a universal replacement for common central AC and heat pump brands, including Carrier, Goodman, Trane, Lennox, Rheem and York, as long as the µF and voltage match.

What is included in the box?

The capacitor itself. Mounting straps and bleed resistors are not listed, so reuse your existing bracket.

About the Coralvolt 45+5 µF Dual Run Round HVAC Capacitor – 370/440V AC

This is a 45+5 µF dual run round capacitor for central AC and heat pump systems. It is rated 370/440V AC at 50/60 Hz and is meant to replace a failed dual-run capacitor. It is compatible with Carrier, Goodman, Trane, Bryant, Payne, Lennox, Rheem and York systems.

It is built with self-healing metallized CBB65 polypropylene film and non-PCB synthetic plant oil. The construction is surge-resistant and rated for operating temperatures from -40°C to +70°C. It has 10,000 AFC anti-explosion protection and safety switch integration, and is certified E332171 / C22.2 NO.190 AMB46C. It is factory-tested to OEM specifications.

Standard 1/4" quick-disconnect spade terminals are stamped for wire identification: C for Common, HERM for Compressor and FAN for Fan Motor. To match an old capacitor, use the same µF rating, the same round or oval shape, and a voltage rating of 370V or 440V. A 440V capacitor can replace a 370V one, but not the other way around. Turn off power and discharge the old capacitor before installing.
