The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-temperature safety control for the WFM18090S4BXCB furnace. This normally-closed thermal switch opens the ignition/gas circuit if it senses an over-temperature or flame-rollout condition, shutting the furnace down to prevent damage and hazard. Because it is a manual-reset device, it must be physically reset (button) after tripping — a deliberate design that forces a technician to diagnose the root cause (blocked flue, cracked heat exchanger, restricted airflow) before the furnace can run again.

Type: Manual-reset thermal limit / rollout safety switch
Contacts: Normally closed (opens on over-temperature)
Reset: Manual push-button reset
Fits: Goodman WFM18090S4BXCB and compatible models
Function: High-limit / flame-rollout overheat protection

OEM vs. Generic

The genuine Goodman OEM switch is factory-calibrated to the exact trip temperature specified for this furnace. A safety control is the wrong place to save a few dollars — a generic switch with the wrong set point can nuisance-trip or, worse, fail to protect the equipment. Always match the OEM part number for safety devices.

Installation Difficulty

Easy. Typically two mounting screws and two spade wire connectors. Disconnect power at the breaker, note the wire positions, swap the switch, and reconnect. If the switch tripped, have the underlying cause diagnosed before returning the unit to service.
