The Goodman 0130F00038 is a genuine OEM auxiliary (high) limit switch engineered for the Goodman/Amana ACEC800603AXAB and compatible units. This light-blue thermal switch monitors temperature inside the heat exchanger/blower compartment and cuts power to the burners or heating element if it exceeds the factory-set trip point, protecting your equipment from overheating, cracked heat exchangers, and nuisance damage.
Generic limit switches are often calibrated to a different trip temperature, which can cause short-cycling or fail to protect the heat exchanger. This genuine OEM 0130F00038 is matched to the exact factory trip point and terminal layout, ensuring correct, safe operation and preserving any equipment warranty.
Easy (1 of 5). Two screws and a pair of spade connectors. Always disconnect power before servicing. If you are unsure about thermal-safety components, consult a licensed HVAC technician.
