58STA110-12122: Carrier Star Plus 110,000 BTU Upflow Platform Service
The Carrier 58STA110 Star Plus series is an 80% AFUE upflow platform with the 110,000 BTU configuration at the top of the BTU range for this product line. At 110,000 BTU the inducer handles the greatest combustion gas volume in the Star Plus family, the furnace cycles most aggressively on cold days, and the igniter accumulates thermal cycles faster than lower-output siblings. The Carrier furnace troubleshooting guide covers fault code blink patterns for the 58STA platform control board.
Most Replaced Parts on the Carrier 58STA110-12122
Igniter for the Carrier 58STA110-12122
At 110,000 BTU the 58STA110-12122 cycles frequently in cold weather, accumulating igniter thermal stress at a higher rate per season than lower-output Star Plus models. Testing resistance at room temperature with power off confirms or rules out igniter failure in under two minutes before any other component is inspected.
Carrier 58STA110-12122 Flame Sensor
The flame sensor confirms sustained combustion by passing a micro-amp signal back to the control board after ignition. An oxidized sensor causes the furnace to ignite and shut off within seconds before lockout. Annual cleaning with fine steel wool extends sensor service life on the Star Plus platform and eliminates most early-season nuisance lockouts.
Draft Inducer Motor for the 58STA110-12122
The inducer on the 58STA110-12122 is sized for 110,000 BTU combustion gas throughput and must not be substituted with an inducer from a lower-output Star Plus configuration. At this output class the inducer accumulates more annual operating hours per heating season than 90,000 or 70,000 BTU siblings. Grinding at inducer startup indicates bearing failure that should be addressed before seizure causes a complete heating failure.
Blower Motor for the Carrier 58STA110-12122
The 110,000 BTU blower motor on the 58STA110-12122 must move adequate air volume across the heat exchanger to prevent limit switch trips. Test the run capacitor before ordering a replacement motor. A failing capacitor produces the same slow-start and reduced-speed symptoms as a failed motor winding at a fraction of the motor replacement cost.
Control Board for the Carrier 58STA110-12122
Read and document the LED fault code before ordering any replacement component. The 12122 configuration designation should be confirmed from the data plate when ordering a replacement board. A board that produces the same fault code after all identified components have tested good is a strong indicator of board failure.

Carrier 58STA110-12122 Furnace Parts FAQ
What is the BTU output and efficiency of the Carrier 58STA110-12122?
The Carrier 58STA110-12122 is a 110,000 BTU input, 80% AFUE upflow gas furnace from Carrier’s Star Plus series. The 110 in the model designation identifies 110,000 BTU capacity and the 12122 identifies the cabinet width and production configuration.
How is the Carrier 58STA110-12122 different from the 58STA090?
The 58STA110-12122 delivers 110,000 BTU while the 58STA090 delivers 90,000 BTU on the same Star Plus platform. The inducer motor and heat exchanger are sized for each output class and must not be cross-substituted between the 110 and 090 configurations.
Why does my Carrier 58STA110-12122 inducer make noise at startup?
Grinding or squealing at inducer startup on the 58STA110-12122 indicates bearing wear accumulated over years of heating season operation. At 110,000 BTU the inducer handles more combustion gas volume per cycle than lower-output Star Plus models, placing additional annual hours on the bearing. Schedule replacement before complete seizure causes a total heating failure.
How do I read the fault code on the Carrier 58STA110-12122?
The control board LED on the 58STA110-12122 flashes a two-digit blink code. Count the first group of flashes, note the pause, then count the second group. Match the pattern to the fault code chart on the sticker inside the blower compartment access panel.
