The Goodman 0130F00036 Limit Switch (Pink) is a genuine OEM high-temperature safety control for the AMH81155CXCC gas furnace. This pink-coded thermal limit switch monitors heat-exchanger and plenum temperature and opens the circuit to shut off the burners if the furnace overheats — protecting against restricted airflow, a failed blower, or a dirty filter. The color coding identifies its specific trip temperature; using the correct pink switch is essential for safe, code-compliant operation. A tripped or failed limit causes no-heat, short cycling, or a furnace that runs the blower but won't fire.
The genuine OEM pink 0130F00036 is calibrated to the exact trip temperature the AMH81155CXCC was engineered for. Generic or wrong-color limits can trip too early (nuisance no-heat) or too late (a genuine safety risk). Always match the OEM color code — this part guarantees the correct calibration and mounting fit.
Easy (2/5). Turn off power, remove two mounting screws, disconnect the two spade terminals, and install the replacement in the same orientation — about 15 minutes. Verify the furnace cycles normally and the overheat cutout resets after installation.
