The Goodman B1370187 is a genuine OEM 160°F primary high-limit switch for the GMNT060-3B gas furnace. Positioned on the heat exchanger or supply plenum, this auto-reset control is the furnace's main overheat protection. It continuously monitors supply-air temperature and shuts off the burners if the furnace overheats due to low airflow, keeping the heat exchanger and cabinet within safe operating limits.

Specifications

Type: Primary high-limit switch
Trip temperature: 160°F
Reset: Automatic reset
Function: Normally closed, opens on overheat
Compatibility: Goodman GMNT060-3B furnace
OEM Part Number: B1370187

OEM vs. Generic

The OEM switch is calibrated to Goodman's precise 160°F set point and uses the correct mounting flange and terminal spacing. A generic high-limit with the wrong trip point can either nuisance-trip during normal heating or fail to protect the heat exchanger. Because this is the furnace's primary safety limit, OEM is strongly recommended.

Installation Difficulty

Easy. Shut off power, disconnect the two wires, remove the two mounting screws, and install the replacement in the identical position. If the limit was tripping, diagnose airflow issues (filter, blower, ductwork) before returning the unit to service.
