The Goodman 0130F00038 Auxiliary Limit Switch (light blue) is a genuine OEM safety control engineered for the ADSH800603AXAB gas furnace and compatible Goodman/Amana platforms. This normally-closed thermal limit monitors heat-exchanger and blower-compartment temperatures, opening the circuit to shut off the gas valve if the unit overheats — protecting the furnace and your home from unsafe operation.
The genuine OEM 0130F00038 arrives with the exact factory-calibrated trip temperature, so the furnace cycles on the setpoint the engineers intended. Generic universal limits often carry a nearby but not identical rating, which can cause nuisance trips or allow the exchanger to run hotter than designed. For a safety component, we recommend OEM.
Easy (2/5). Kill power at the disconnect, remove two mounting screws, unplug the two spade terminals, and reverse to install. Most homeowners with a nut driver and 15 minutes can complete this repair. Always verify power is off and test furnace operation after installation.
