Goodman 10123537 Manual Reset Limit Switch (Gray)

The Goodman 10123537 is a gray-coded manual reset limit switch for the WGFM295070V4CAB gas furnace. The color code identifies its specific trip temperature within the furnace's safety network, distinguishing it from companion limits such as the 10123533. It protects the heat exchanger and burner assembly by cutting the ignition circuit when temperatures exceed the safe threshold, then locking out until it is manually reset.

Specifications

Type: Manual reset over-temperature limit switch
Color code: Gray (trip-point specific)
Reset: Push-button manual reset with lockout
Fits: Goodman/Amana WGFM295070V4CAB gas furnace
Terminals: 1/4 in. quick-connect spade
Construction: Snap-action bimetal disc, high-temp housing

OEM vs. Generic

The gray color code matters — it corresponds to a factory-calibrated trip temperature for this exact position in the furnace. This genuine OEM Goodman switch guarantees the correct setpoint and mounting fit. Generic substitutes rarely match the color-coded temperature, risking nuisance lockouts or, worse, delayed protection. Always match OEM for coded safety limits.

Installation Difficulty

Easy (2/5). Disconnect power and gas, unscrew the old switch, move the two spade wires, and mount the replacement. About 10–15 minutes with a nut driver. Verify you are replacing the gray-coded limit in the same location, and confirm proper airflow before returning the unit to service.
