Goodman B1370155 Auxiliary Limit Switch (120°F)

The B1370155 is a genuine OEM auxiliary limit switch for the Goodman GMPE125-5 gas furnace. Mounted in the blower compartment, this secondary limit protects against heat buildup caused by a restricted blower, dirty filter, or blocked return — conditions the primary high limit may not catch. If cabinet temperature exceeds its 120°F set point, it opens the control circuit to shut the furnace down safely.

Specifications

Set point / open temperature: 120°F
Type: Auxiliary (secondary) limit switch
Function: Blower-compartment overheat safety
OEM Part Number: B1370155
Compatible model: Goodman GMPE125-5 furnace
Brand: Goodman (genuine OEM)

OEM vs. Generic

The OEM Goodman switch is calibrated to the exact 120°F trip point and mounting footprint of the GMPE125-5. Generic replacements with different set points can cause premature shutdowns or fail to protect the blower housing. For a safety limit, matching the OEM specification is the right call.

Installation Difficulty: Easy

A quick two-wire, single-screw swap — about 10–15 minutes with a nut driver. Shut off electrical power and gas before servicing. If the auxiliary limit keeps tripping, check the air filter, blower wheel, and ductwork for restriction before condemning the switch.

Fits Goodman GMPE125-5. Confirm the 120°F rating and part number against your existing switch before ordering.
