Goodman B1370198 Primary Limit Switch — 150°F

The B1370198 is a genuine OEM 150°F primary high-limit switch for the Goodman/Amana AMH80903BXAA gas furnace. Positioned on the heat-exchanger bulkhead, this auto-reset switch is the furnace's main overheat protection: if supply-air temperature climbs past the setpoint due to restricted airflow, it shuts off the gas valve to prevent heat-exchanger damage. A furnace that heats briefly then shuts down repeatedly is often tripping this limit.

Specifications

Trip temperature: 150°F (opens on rise)
Reset: Automatic
Function: Primary high-limit / overheat protection
OEM part number: B1370198
Fits: Goodman & Amana AMH80903BXAA furnace

OEM vs. Generic

The OEM B1370198 is set to the precise 150°F trip point and uses the correct bracket and disc diameter for this cabinet. Substituting a limit with the wrong temperature rating risks nuisance lockouts or heat-exchanger overheating. On a primary safety limit, OEM specification is the right call.

Install Difficulty

Easy — two screws and two push-on terminals. Most homeowners finish in under 15 minutes. Disconnect power before starting, and if the new limit keeps tripping, check the filter, blower, and ductwork rather than bypassing it.
