The Goodman 20269903 Auxiliary Limit Auto-Reset Switch is a genuine OEM high-temperature safety control for the GMPE075-3 gas furnace. This normally-closed thermal switch opens the control circuit if the furnace overheats — from a dirty filter, blocked return, or failing blower — then automatically resets once temperatures return to normal. A failed switch can cause nuisance shutdowns or, if stuck, compromise the furnace's overheat protection.

OEM vs. Generic

This genuine Goodman OEM switch is calibrated to the exact trip and reset temperatures specified for the GMPE075 cabinet. Substituting a generic limit with the wrong temperature rating can either trip prematurely or fail to protect the heat exchanger. Always match the OEM temperature spec for safety-critical controls like this one.

Installation Difficulty

Easy (2 of 5). Turn off power and gas, remove the two mounting screws, transfer the wire leads to the new switch, and remount. A quick 10–15 minute swap. Address the root cause of any overheat (airflow restriction) before returning the furnace to service.
