The Goodman 10123529 is a genuine OEM manual-reset limit switch designed for the WFM18140S5DNCC furnace. This normally-closed thermal safety switch opens the control circuit and shuts down the burners if it senses an over-temperature or flame-rollout condition. Because it is a manual-reset device, it stays open after a fault until you physically press the reset button — a deliberate safety design that forces inspection before the furnace can fire again.

Specifications

Type: Manual-reset thermal limit / rollout switch
Configuration: Normally closed (opens on high temperature)
Reset: Manual push-button
Function: Over-temp and flame-rollout safety cutout
Fits: Goodman WFM18140S5DNCC and compatible models
OEM Part Number: 10123529

OEM vs. Generic

The OEM switch is calibrated to the furnace's exact trip temperature and mounting footprint — critical for a safety component. A generic equivalent may match form and rating at lower cost, but we strongly recommend OEM for any flame-rollout or high-limit safety device to ensure correct trip point and certification.

Install Difficulty

Easy (1 of 5). About 10 minutes. Shut off power and gas, unplug the two spade terminals, remove the mounting screws, and install the new switch in the same orientation. If it tripped, investigate the root cause (blocked flue, dirty burners, cracked heat exchanger) before returning the furnace to service.
