Restore dependable heating from your Carrier 58STA070-10112 furnace with genuine OEM replacement parts from Repair Clinic. The 58STA070-10112 is a 70,000 BTU upflow 80% AFUE single-stage gas furnace in Carrier’s 58STA series; the 070 designates 70,000 BTU input, the 10 indicates the cabinet width, and the 112 is the production sequence identifier. Because Carrier and Bryant are sister brands under Carrier Global, the 58STA070-10112 and its Bryant equivalent at the same configuration use identical components. Parts most frequently replaced include the draft inducer motor, blower motor, igniter, control board, and flame sensor.

About the Carrier 58STA070-10112: 70,000 BTU Upflow 80% AFUE Single-Stage Platform and Bryant Equivalence
The Carrier 58STA070-10112 is an 80% AFUE non-condensing upflow gas furnace using standard metal B-vent exhaust. The 58STA series uses a PSC blower motor and a single-stage gas valve, making it a straightforward service platform without the condensate management or ECM motor complexity found on Carrier’s higher-efficiency condensing lines. As a Carrier Global sister brand, the Bryant equivalent to the 58STA070-10112 uses identical inducer motors, blower motors, igniters, flame sensors, and control boards with no modification.

Most Replaced Parts on the 58STA070-10112
58STA070 Draft Inducer Motor and Pressure Switch Lockout
The Carrier 58STA070 inducer motor draws combustion gases through the heat exchanger and exhausts them through the B-vent before ignition begins. Worn bearings cause it to run slowly or stall, reducing the negative pressure the pressure switch monitors; when the switch fails to close, the furnace locks out before the igniter energizes. A grinding or rattling sound during the pre-purge stage followed by a no-heat lockout is the primary indicator. Browse Carrier furnace inducer motor parts.
Carrier 58STA070-10112 Blower Motor and Weak Airflow
The blower motor is a PSC motor that circulates conditioned air through the supply duct system after each heating cycle. Weak airflow at registers and repeated high-limit trips indicate blower motor performance below rated speed. Test the blower run capacitor before condemning the motor; a capacitor outside its rated microfarad range produces identical slow-running symptoms at a fraction of the motor replacement cost. Browse Carrier furnace blower motor parts.
58STA070-10112 Igniter Wear and Burner No-Fire Condition
The hot surface igniter is a silicon carbide element that fractures along stress lines after thousands of heat cycles. A cracked igniter may glow adequately at room temperature but fail to reach ignition temperature when cold air flows across it during the pre-ignition stage, resulting in a no-fire condition while the inducer and pressure switch operate normally. Replace the igniter when any visible crack is present. Browse Carrier furnace igniter parts.
58STA070-10112 Control Board Fault Codes
The control board manages the complete heat cycle and reports faults through a diagnostic LED blink code on the board’s face. Note the blink count and match it to the fault chart on the lower access panel before ordering any replacement component. A board fault can lock the furnace at any stage — verify the LED code before condemning the board or any upstream component. Browse Carrier furnace control board parts.
Carrier 58STA070 Flame Sensor Short-Cycle Fix
The flame sensor is a single-rod ionization probe that confirms burner ignition within seconds of the gas valve opening. Carbon and oxide buildup reduces its conductivity; three failed ignition attempts trigger a hard lockout. Cleaning the rod extends its service life, but a rod with visible pitting or glazing requires replacement. Browse Carrier furnace flame sensor parts.

Carrier 58STA070-10112 Furnace Parts FAQ
Why does my Carrier 58STA070-10112 run the inducer but never fire the burner?
When the 58STA070-10112 runs its inducer continuously without advancing to ignition, the most common causes are a failed pressure switch preventing draft confirmation, a stalled inducer motor not generating sufficient negative pressure, or a cracked igniter that never energizes. Check the LED fault code on the control board to isolate which stage is failing before replacing any component.
Are Carrier 58STA070 and Bryant furnace parts interchangeable?
Yes. Carrier and Bryant are sister brands under Carrier Global sharing the same manufacturing platform. The inducer motor, blower motor, igniter, flame sensor, and control board used in equivalent Carrier 58STA070 and Bryant furnace configurations are identical and fully interchangeable with no modification.
How do I read the fault code on my Carrier 58STA070-10112 control board?
The control board displays a repeating LED blink pattern when a fault is active. Count the flashes in the repeating sequence and match the number to the diagnostic chart printed on the interior of the furnace’s lower access panel. The chart identifies which component or safety circuit triggered the lockout.
What causes the Carrier 58STA070 blower motor to run but produce weak airflow?
Weak airflow with the blower running most commonly indicates the run capacitor has failed, reducing the motor’s torque and speed below the rated design point. Replace the capacitor first as it is lower cost than the motor itself. If airflow remains weak after a capacitor swap, replace the blower motor.
