The INTERNATIONAL COMFORT PRODUCTS p291-1504 is an oval run capacitor rated at 15 microfarads (MFD) and 440 volts, designed for use in residential and light commercial HVAC systems. Run capacitors maintain the continuous phase shift needed to keep single-phase motors running at proper torque and efficiency. This part is used in air conditioner condensing units and heat pumps, typically on the compressor or condenser fan motor circuit. A licensed HVAC technician installs this component as part of routine service or when diagnosing motor start or run failures.
This capacitor is suited for condensing unit applications where the original equipment called for a 15 MFD, 440-volt oval-style run capacitor. The 440-volt rating provides operating margin in applications where supply voltage may vary. It is commonly replaced during seasonal tune-ups or when a unit exhibits symptoms such as hard starting, slow motor spin-up, or compressor failure to run.
Designed as an OEM replacement run capacitor for INTERNATIONAL COMFORT PRODUCTS HVAC central air and heat pump systems requiring a 15 MFD, 440-volt oval run capacitor.
Installation should be performed by a licensed HVAC technician. Always disconnect and lock out power to the unit before servicing capacitors, and discharge the existing capacitor safely before handling, as run capacitors can retain a dangerous charge after power is removed. Confirm the MFD rating and voltage rating of the replacement match the original equipment specifications before installation. Follow applicable NEC guidelines for electrical safety during service.
