The Carrier 58MXA080-13112 is an 80,000 BTU, 80% AFUE upflow gas furnace from Carrier’s WeatherMaker 9200 series in the 12-inch cabinet configuration. The WeatherMaker 9200 platform has a long service history and is closely related to the Payne PG8MAA, making it one of the most well-documented Carrier residential furnace series. Repair Clinic stocks genuine Carrier OEM parts for the 58MXA080-12 and the 16-inch sibling 58MXA080-16, covering the control board, igniter, flame sensor, inducer assembly, and limit switches.

58MXA080 Platform: WeatherMaker 9200 and the Payne PG8MAA Connection
The Carrier 58MXA080 and Payne PG8MAA are the same furnace marketed under two brand names at different price points. The 58MXA080-13112 cabinet is 12 inches wide and the 58MXA080-16 is 16 inches wide; most ignition and control components are shared between both cabinet widths, but blower motor specifications and some cabinet panel dimensions differ. The Carrier furnace troubleshooting guide covers fault code blink patterns for the shared platform control board used in all 58MXA variants.
Most Replaced Parts on the Carrier 58MXA080-13112
Draft Inducer Motor Assembly
The 58MXA080-13112 inducer pre-purges combustion gases before ignition and maintains draft through every heating cycle. Because the WeatherMaker 9200 has been installed across many residential properties over decades, induced replacement is one of the most common service events on this platform. Carrier OEM inducer assemblies preserve the draft specifications the pressure switch is calibrated to verify.
Hot Surface Igniter
The 58MXA080-12 uses a silicon nitride igniter that must reach temperature within the control board timing window on every heating call. A furnace that attempts ignition without producing heat, then repeats before locking out, almost always has a failed igniter. Testing resistance across the igniter terminals with power off confirms an open-circuit failure. Handle the element only by its ceramic base during installation.
58MXA080-13112 Control Board
The Carrier 58MXA080-12 control board manages ignition sequencing and contains the LED diagnostic system for this model. The board must match the 12-inch cabinet platform specifications. A board from the 16-inch 58MXA080-16 may have different blower timing for the larger blower assembly and should not be cross-substituted without confirming part number compatibility.
58MXA080-12 Flame Sensor
The 58MXA080-13112 flame sensor rod develops an oxide film over time that reduces its electrical conductivity and causes nuisance shutdowns. Light sanding with fine-grit steel wool can restore adequate conductivity temporarily, but a deeply oxidized rod should be replaced with the OEM Carrier component for reliable long-term performance.
Limit Switch
The 58MXA080-12 uses both a primary and a secondary limit switch to protect the heat exchanger from overtemperature. A limit that trips consistently under normal operating conditions indicates a restriction in the airflow path that must be resolved before replacing the switch. The most commonly overlooked airflow restriction on the WeatherMaker 9200 platform is a dirty blower wheel rather than a dirty filter.

Carrier 58MXA080-13112 Furnace Parts FAQ
What is the Carrier WeatherMaker 9200 and how does it relate to the 58MXA080?
The WeatherMaker 9200 is the marketing name for the Carrier 58MXA series. The 58MXA080-13112 is the 80,000 BTU, 12-inch cabinet version of this platform. Parts for the WeatherMaker 9200 and the 58MXA080 reference the same components.
What is the difference between the 58MXA080-13112 and 58MXA080-16?
The dash suffix indicates the cabinet width. The 58MXA080-13112 uses a 12-inch wide cabinet, while the 58MXA080-16 uses a 16-inch wide cabinet. Most service components including the igniter, flame sensor, and control board are shared. Blower motor specifications and some cabinet parts differ by cabinet width.
How do I read the fault code on the Carrier 58MXA080-13112?
The LED on the 58MXA control board flashes a two-digit code. Count the first set of flashes, pause, then count the second set. Match the pattern to the fault code chart on the inside of the furnace access panel.
Is the Carrier 58MXA080 a condensing furnace?
No. The 58MXA080 is an 80% AFUE non-condensing furnace. It uses standard metal B-vent and does not produce condensate during normal operation. The Payne PG9MAA is the shared-platform condensing version.
