The Payne PG8MAA036110AAJA is the 110,000 BTU configuration within the PG8MAA series, an 80% AFUE single-stage furnace sharing its engineering with the Carrier 58MXA platform. The PG8MAA prefix indicates an 80% AFUE upflow gas furnace in Payne’s value-tier lineup. At 110,000 BTU input the PG8MAA036110AAJA is one of the larger models in the series and requires substantial ductwork to deliver its output without tripping the limit switch. Repair Clinic stocks genuine Payne OEM parts for the PG8MAA036110AAJA and the related PG8MAA036060 and PG8MAA036080 variants.

PG8MAA036110AAJA: The Payne and Carrier 58MXA Shared Platform at 110,000 BTU
The PG8MAA036110AAJA is Payne’s value-tier equivalent of the Carrier 58MXA at 110,000 BTU. The suffix 036110 identifies three-ton airflow capacity at 110,000 BTU input. At this output level the furnace requires properly sized return ductwork to prevent heat exchanger overtemperature, and any return duct undersizing that would be marginal in a lower-BTU installation becomes a consistent problem at 110,000 BTU. The Carrier furnace troubleshooting guide covers fault code blink patterns for the shared 58MXA platform control board used in the PG8MAA036110AAJA.
Most Replaced Parts on the Payne PG8MAA036110AAJA
Draft Inducer Motor
At 110,000 BTUs, the PG8MAA036110AAJA inducer motor handles substantial combustion gas volume on every heating cycle. High-BTU furnaces cycle hard in cold weather, accumulating inducer bearing hours more rapidly than lower-output models. Grinding or squealing during the pre-purge phase should prompt immediate inducer replacement. A seized inducer means no heat until the part is installed.
PG8MAA036110 Igniter
The PG8MAA036110AAJA igniter heats to temperature within 17 to 34 seconds of being energized. Because this is a high-output furnace that runs frequently in cold climates, the igniter accumulates more thermal cycles per season than a lower-output model in the same home. Annual inspection is advisable in cold-climate installations where the furnace cycles frequently during extended cold spells.
Payne PG8MAA Control Board
The PG8MAA036110AAJA control board manages the 110,000 BTU heating sequence and three-ton blower timing. A board that generates the same fault code repeatedly after all other identified components have been tested and found good is a strong indicator of board failure. Always document the specific blink code before any replacement, as it identifies which component is failing on this platform.
Blower Motor Assembly
The blower motor on the PG8MAA036110AAJA is sized for three-ton airflow capacity. A motor that begins to draw high amperage or runs warm indicates winding degradation. Testing the run capacitor is always the first step, since a failing capacitor mimics many symptoms of winding failure at a fraction of the replacement cost.
High-Limit Switch for PG8MAA036110
The PG8MAA036110AAJA at 110,000 BTUs requires substantial airflow to prevent heat exchanger overtemperature. Return ductwork undersizing is a common installation fault in high-output furnace applications that causes the limit to trip repeatedly regardless of filter condition. Address the duct system root cause before replacing the switch.

Payne PG8MAA036110AAJA Furnace Parts FAQ
Is the Payne PG8MAA the same as the Carrier 58MXA?
Yes. The Payne PG8MAA and Carrier 58MXA share the same platform and most parts are interchangeable. Payne is Carrier’s value-tier brand and the engineering of both models is essentially identical.
How do I read the fault code on a Payne PG8MAA036110AAJA control board?
The LED blinks in a two-digit pattern. Record the number of flashes in each group and match the code to the fault code chart printed on the inside of the blower compartment door panel.
Why does my PG8MAA036110AAJA limit switch keep tripping even with a clean filter?
At 110,000 BTUs the furnace requires substantial airflow through both the return and supply systems. Undersized return ductwork, a dirty blower wheel, closed supply registers, or a failing blower motor run capacitor can all restrict airflow enough to trip the limit switch even with a fresh filter.
How do I know when the inducer motor on my PG8MAA036110AAJA needs replacement?
Grinding or squealing during the pre-purge phase at startup is the first indication of bearing failure. Replace the inducer before the bearing seizes completely. A seized inducer means no heat until the part arrives and is installed.
