The Goodman 10123534 Manual Reset Limit Switch is a genuine OEM safety control for the WFD195090S4CAA gas furnace. This high-limit switch monitors heat-exchanger and plenum temperature and opens the control circuit if the furnace overheats — most often due to a dirty filter, blocked airflow, or a failing blower. Because it's a manual reset design, it locks out and must be pressed to restore heat, alerting the homeowner or technician that an overheat condition occurred rather than silently re-cycling.

OEM vs. Generic

The genuine OEM switch is calibrated to the exact trip and reset temperatures Goodman specifies for the WFD195090S4CAA. Generic limit switches with the wrong temperature rating either nuisance-trip during normal operation or, worse, fail to open when they should — defeating a critical safety function. Always use OEM for safety controls.

Installation Difficulty

Easy (2/5). Disconnect the two spade terminals, remove the mounting screws, and install the replacement in the same orientation. A 10–15 minute job — but investigate why the switch tripped (airflow, filter, blower) before returning the unit to service. Cut power at the disconnect first.
