Heat Controller 15B0013N03 Oval Run Capacitor 5 Mfd 370V

Product Description

The HEAT CONTROLLER 15B0013N03 is an oval run capacitor rated at 5 microfarads (MFD) and 370 volts, designed for use in single-phase motor circuits found in HVAC systems. Run capacitors maintain the phase shift needed to keep PSC motors running efficiently after startup. This oval-style unit is a common replacement component installed by licensed HVAC technicians during routine maintenance or motor failure diagnosis. Its compact oval form factor fits standard capacitor brackets used in residential and light commercial equipment.

This capacitor is suited for residential and light commercial HVAC applications where a 5 MFD, 370-volt oval run capacitor is specified. Typical installations include condenser fan motors and blower motors in split-system air conditioners and heat pumps. Technicians reach for this part when a weak or failed capacitor is identified as the cause of motor startup issues, reduced airflow, or compressor short-cycling.

Key Features

• 5 MFD capacitance rating for precision motor phase support
• 370-volt rating suitable for standard single-phase HVAC motor circuits
• Oval form factor fits common capacitor mounting brackets
• Direct replacement for failed or degraded run capacitors in HVAC equipment

Compatibility

Designed as an OEM-style replacement run capacitor for residential and light commercial HVAC systems requiring a 5 MFD 370-volt oval capacitor.

Installation Notes

Run capacitors must be installed by a qualified HVAC technician. Always disconnect and lock out power to the unit before handling capacitors, as they can retain a dangerous charge even after power is removed — discharge the capacitor safely before touching terminals. Verify that the replacement capacitor matches the MFD rating and voltage rating specified on the motor nameplate before installation. Follow all applicable local electrical codes and NEC guidelines when servicing capacitor circuits.
