The genuine OEM Goodman 10123535 red manual reset limit switch is a high-temperature safety control for the Goodman WGFM195045S3BAC gas furnace. The red button typically identifies a burner/flame rollout switch — a normally-closed thermal device that instantly cuts the gas and ignition circuit if flames roll out of the burner box due to blocked venting, a cracked heat exchanger, or restricted combustion air. This is one of the furnace's most important safety devices, guarding against fire and carbon-monoxide exposure.

Specifications

OEM Part Number: 10123535
Type: Manual reset rollout / high-limit safety switch (red)
Action: Normally closed, opens on flame rollout / over-temperature
Reset: Manual (push-button)
Color/ID: Red button
Fits: Goodman WGFM195045S3BAC furnace

OEM vs. Generic

The OEM 10123535 carries the precise trip temperature and terminal layout Goodman engineered for this furnace, ensuring dependable protection and a plug-in fit. Substituting a generic rollout switch with a different rating risks failing to trip during a genuine rollout event — an unacceptable safety compromise. Always use the factory-matched part.

Installation Difficulty

Moderate. Turn off power and gas, disconnect the spade terminals, unscrew the switch from the burner bracket, and mount the replacement in the identical position and orientation. Roughly 15–20 minutes. A repeated rollout trip signals a serious combustion or venting fault — have a licensed HVAC technician inspect the heat exchanger and flue before restoring operation.
