Carrier P291-1554 Run Capacitor

The Carrier P291-1554 is a 15/5 MFD dual run capacitor designed for compatible HVAC condensing equipment. Rated at 440 VAC, this oval capacitor combines two capacitance sections in one enclosure to support both compressor and condenser fan motor run circuits.

The 15 µF section and 5 µF section provide the specified capacitance required by compatible equipment, while the common terminal serves both circuits. This Carrier dual run capacitor is intended for replacement applications where the equipment specifies a 15/5 µF, 440 VAC oval configuration.

When diagnosing a failed HVAC run capacitor, verify capacitance with an appropriate meter and inspect the terminals, wiring, contactor, compressor, and condenser fan motor for related electrical problems. Always match the required microfarad ratings and use a voltage rating that meets the equipment specification.

Confirm the original part number and unit model before installation.

Common Questions

What are the specifications of the Carrier P291-1554?
The P291-1554 is an oval dual run capacitor rated at 15/5 MFD (µF) and 440 VAC.

What does 15/5 MFD mean?
The capacitor contains two capacitance sections. One is rated at 15 µF and the other at 5 µF, with a common connection shared between the circuits.

What does a dual run capacitor do?
In compatible HVAC equipment, a dual run capacitor provides the required capacitance for two motor circuits, typically the compressor and condenser fan motor.

Can I replace a 15/5 MFD capacitor with a different capacitance?
The replacement should match the capacitance specified by the equipment manufacturer. Do not substitute a different microfarad rating simply because the capacitor has the same physical shape or terminal arrangement.

How do I confirm the P291-1554 fits my HVAC unit?
Verify the equipment model and serial number, original capacitor part number, required 15/5 µF capacitance, voltage rating, physical configuration, and applicable manufacturer service information before replacement.

What should be checked if the run capacitor fails?
Inspect the capacitor terminals and wiring along with the contactor, compressor, condenser fan motor, and associated electrical connections. A capacitor failure can occur alongside other electrical or motor problems.
