Hvac cd50+5x370r Dual Run Capacitor 50+5 Mfd 370V

Product Description

The HVAC cd50+5x370r is a round dual run capacitor rated at 50 microfarads (MFD) plus 5 MFD at 370 VAC. Dual run capacitors serve two motor loads simultaneously — typically the compressor and the condenser fan motor — within a single sealed housing. This round-style unit is a standard format found in residential and light-commercial split systems and package units. Licensed HVAC technicians install and replace these capacitors as part of routine cooling-season service or when diagnosing motor start or run failures. The 50+5 MFD rating and 370 VAC rating must match the equipment nameplate before installation.

This capacitor is suited for use in air-conditioning systems where the original equipment calls for a round dual run capacitor at these ratings. It supports simultaneous run-duty operation of a compressor motor and a single-phase condenser fan motor. Typical install scenarios include split-system condensing unit service and package-unit capacitor replacement on residential and small-commercial equipment. Always verify the microfarad and voltage ratings against the unit nameplate before replacing.

Key Features

• Dual section design powers compressor and condenser fan motor from a single capacitor body
• Rated 50 MFD plus 5 MFD for split-capacity run-duty applications
• 370 VAC rating suitable for standard single-phase residential and light-commercial HVAC equipment
• Round housing — common form factor for straightforward bracket or strap mounting in condensing units
• Replaces failed or weak dual run capacitors causing hard-start, slow-start, or fan motor issues

Compatibility

Designed as an OEM-style replacement dual run capacitor for single-phase residential and light-commercial HVAC condensing units requiring a 50+5 MFD, 370 VAC round capacitor. Also referenced under part number CD505X370R.

Installation Notes

Capacitor replacement is performed by licensed HVAC technicians. Before servicing, disconnect and lock out power to the condensing unit at the disconnect box and allow time for the existing capacitor to discharge fully — never assume a capacitor is safe to handle immediately after power is cut. Confirm the replacement MFD and voltage ratings match the equipment nameplate exactly; substituting an incorrect rating can damage motors or void equipment warranties. Follow applicable NEC requirements and local codes when servicing electrical components in HVAC equipment.
