This OEM single run capacitor (part number P291-1003) is the factory-specified replacement for the Carrier PG8MAA036110ADJA gas furnace. The run capacitor stores and releases an electrical charge to keep the blower motor running at peak efficiency. When this component degrades or fails, you may notice the blower motor struggling to start, humming without spinning, overheating, or shutting down prematurely — all of which can trigger fault codes and reduce system efficiency. Replacing a failed run capacitor promptly prevents downstream damage to the blower motor itself, which costs significantly more to replace.
Compatibility: Designed for the Carrier PG8MAA036110ADJA gas furnace blower motor circuit. Note: P291-1003 has been superseded by P291-1004 (Hartland Controls, 10 MFD, 440V) — both are cross-compatible and meet or exceed original factory specs. Verify the MFD rating and voltage on your unit's data plate before ordering. Our fitment team is available to confirm compatibility before you buy.
