Goodman 20269903 Auxiliary Auto-Reset Limit Switch

The 20269903 is a genuine OEM Goodman auxiliary high-limit switch built for the AMV81155CXBB gas furnace. This auto-reset thermal safety control monitors temperature at the blower or supply area and opens the circuit if it climbs beyond the rated cutoff, shutting the furnace down to prevent heat-exchanger damage or a fire hazard. When the temperature returns to normal, the switch automatically resets and restores operation — no manual button push required.

OEM vs. Generic

Genuine Goodman limit switches are factory-calibrated to the exact trip temperature the AMV81155CXBB requires. Generic limits may carry a different cutoff point, causing nuisance shutdowns or, worse, failing to trip when they should. On a safety control, OEM calibration matters.

Install Difficulty

Easy to Moderate — remove power, disconnect the two spade terminals, and replace using the same mounting screws. A multimeter continuity check confirms correct operation.
