Value Collection 12904 Motor Run Capacitor 4 Mfd 370V

Product Description

The VALUE COLLECTION 12904 is a single-section motor run capacitor rated at 4 microfarads (MFD) and 370 volts. Motor run capacitors maintain a phase shift in the auxiliary winding of a single-phase AC motor, keeping it running efficiently after startup. This capacitor stands 1.5 inches tall and weighs 0.2 pounds, making it a compact replacement suited for residential and light commercial HVAC applications. HVAC technicians and motor service professionals install these during routine motor replacements or capacitor failure diagnosis on fan motors and compressors.

This capacitor is commonly used in residential and light commercial HVAC systems as a replacement for failed or degraded motor run capacitors on condenser fan motors, blower motors, and other single-phase inductive motor loads rated at 370 volts. Its 4 MFD rating makes it appropriate for smaller fractional horsepower motors found in residential air handlers, condensing units, and similar equipment. Always verify the MFD and voltage rating of the original capacitor before installing a replacement.

Key Features

• 4 MFD capacitance rating for smaller fractional horsepower single-phase motors
• 370-volt rating suitable for standard residential HVAC motor applications
• Compact form factor at 1.5 inches tall and 0.2 pounds
• Single-section design for straightforward replacement installations

Compatibility

Designed as an OEM-style replacement motor run capacitor for single-phase AC motors rated at 4 MFD and 370 volts in residential and light commercial HVAC equipment.

Installation Notes

Motor run capacitors are typically installed by licensed HVAC technicians. Always disconnect and lock out power to the unit before handling capacitors, and discharge the capacitor using an approved discharge tool before touching terminals, as capacitors can retain a dangerous charge after power is removed. Verify that the replacement MFD rating and voltage rating match the original equipment specifications before installation. Local electrical codes and manufacturer service guidelines should be followed throughout the repair.
