My furnace will not ignite. What part is bad?

A furnace that will not ignite after the draft inducer runs typically has a failed igniter. The hot surface igniter should glow bright orange within 60 seconds. If it does not glow at all, it is cracked or burned out. If it glows weakly, it is degrading and should be replaced preventively. Average lifespan: 3 to 7 years.

Is this igniter compatible with Bryant or Payne systems too?

Many Tempstar parts are cross-compatible with Bryant and Payne systems since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across multiple brand labels with different model numbers. To verify cross-compatibility, check your Bryant or Payne equipment service manual for cross-compatible part numbers, or contact info@nationalhvacparts.com with your model number for confirmation.

Overview

The OEM hot surface igniter (HSI) lights the gas burners on your Tempstar T8MPN075B12B1 gas furnace. When the thermostat calls for heat, the control board energizes this 120-volt igniter; it glows orange-hot within seconds and ignites the gas as the valve opens. A cracked, eroded, or electrically open igniter is one of the most frequent causes of a furnace no-heat lockout. This direct-fit replacement (OEM part 1172533) restores dependable first-cycle ignition. On this model the igniter works with gas valve 1172821 (VR8205S snap-mount); replace both together if the valve is also suspect.

Installation Guide

Safety First — Shut off gas and disconnect electrical power; verify zero voltage with a multimeter.
Access — Remove the furnace burner/service panel.
Document — Photograph the igniter wiring and bracket orientation before disconnecting.
Remove — Unplug the igniter connector and remove the mounting screw; handle the old igniter only by its ceramic base.
