Keep your Payne PG8MAA036070 furnace heating dependably with genuine OEM replacement parts from Repair Clinic. The PG8MAA036070 is a 70,000 BTU 80% AFUE upflow gas furnace in Payne’s PG8 series; decoding the model: PG8 identifies the 80% AFUE upflow single-stage platform, M identifies a specific configuration class, AA identifies the cabinet, 036 indicates the nominal capacity class, and 070 indicates 70,000 BTU input capacity. Payne, Carrier, and Bryant are all Carrier Global brand designations sharing the same platform engineering with fully interchangeable service components at equivalent configurations — the PG8MAA036070 and its Carrier and Bryant equivalents at the same configuration use identical parts. Parts most frequently replaced include the igniter, flame sensor, control board, blower motor, and inducer motor. Browse the full Carrier furnace parts catalog for Payne platform components.
Payne PG8MAA036070: 70,000 BTU 80% AFUE Upflow Platform and Carrier Global Family Equivalence
The PG8MAA036070 is an 80% AFUE non-condensing upflow gas furnace using standard metal B-vent with no condensate management. Payne, Carrier, and Bryant are all Carrier Global brand designations sharing the same platform engineering; the PG8MAA036070 and the equivalent Carrier and Bryant furnaces at the same configuration use identical components including the igniter, flame sensor, control board, blower motor, and inducer motor with no modification required. Reading the control board LED fault code blink pattern is the correct first diagnostic step before replacing any component. For diagnostic guidance, visit the Payne furnace repair help section.
Common Payne PG8MAA036070 Replacement Parts and Diagnostic Sequences
PG8MAA036070 Igniter
The hot surface igniter initiates every heating cycle by heating to ignition temperature. A cracked igniter may glow at room temperature but fail when cold air flows across it during the pre-ignition stage. Read the control board fault code first to confirm an ignition failure code; inspect the element under direct light for any visible crack before relying on a resistance reading. Handle replacements only by the ceramic base. Browse Carrier furnace igniter parts.
PG8MAA036070 Flame Sensor
The flame sensor confirms burner combustion to the control board within seconds of the gas valve opening. Oxide buildup on the rod reduces conductivity; when the signal drops below the board’s threshold, the gas valve closes and the furnace short-cycles through multiple attempts before lockout. Annual cleaning extends sensor life, but a rod with visible pitting requires replacement. Browse Carrier furnace flame sensor parts.
PG8MAA036070 Control Board
The control board manages the complete ignition sequence, blower delay, and safety circuit monitoring. Note the LED blink count and match it to the fault chart on the furnace’s lower access panel interior before ordering any component. Browse Carrier furnace control board parts.
PG8MAA036070 Inducer Motor
The inducer motor draws combustion gases through the heat exchanger and exhausts them through the B-vent before ignition begins. A slow-running or stalling inducer produces pressure switch lockout that is often misdiagnosed as a failed switch; verify inducer speed before replacing the switch. Browse Carrier furnace inducer motor parts.
PG8MAA036070 Blower Motor
The blower motor circulates conditioned air through the supply duct system. Test the blower run capacitor before ordering a replacement motor; a capacitor outside its rated microfarad range produces identical weak-airflow symptoms at a fraction of the motor replacement cost. Browse Carrier furnace blower motor parts.

Payne PG8MAA036070 Furnace Parts FAQ
Why is my Payne PG8MAA036070 furnace not turning on?
Read the control board LED fault code blink pattern first; the code identifies the specific stage of the ignition sequence that has failed. Common causes of no-heat on the PG8MAA036070 are a cracked igniter not reaching ignition temperature, a dirty flame sensor causing lockout after attempted ignition, or a pressure switch fault from a slow-running inducer or blocked pressure hose. The LED code directs the diagnosis before any component is replaced.
Are Payne PG8MAA036070 parts interchangeable with Carrier or Bryant furnaces?
Yes. Payne, Carrier, and Bryant are all Carrier Global brand designations sharing the same platform engineering. The PG8MAA036070 and its Carrier and Bryant equivalents at the same configuration use identical igniter, flame sensor, control board, blower motor, and inducer motor with no modification required.
How do I find the correct PG8MAA036070 parts list?
The PG8MAA036070 parts list and interactive diagram are available on the Repair Clinic product page under the Diagrams tab. Components are organized by assembly section, and the parts list filters to confirm which Carrier Global platform components apply specifically to the PG8MAA036070 configuration before ordering.
Why is airflow weak from my Payne PG8MAA036070?
Weak airflow with the blower running most commonly indicates a failed blower motor run capacitor reducing motor torque and speed below the rated design point. Replace the capacitor before ordering a replacement motor; a capacitor outside its rated microfarad range produces identical weak-airflow symptoms at a fraction of the motor cost. If airflow remains weak after a capacitor swap, replace the blower motor.
