The Goodman 0130F00038 Auxiliary Limit Switch (light-blue body) is a genuine OEM thermal safety control for the Amana/Goodman AMVC800805DNAA gas furnace. This normally-closed switch opens the control circuit if the blower compartment or heat exchanger exceeds its safe temperature, shutting down the burners to prevent overheating.
The light-blue color designates a specific trip temperature calibrated for this furnace. OEM 0130F00038 guarantees the correct set point — a critical safety spec. Substituting a switch with a different trip point can allow overheating or cause nuisance shutdowns, so OEM is strongly recommended for this part.
Easy (2/5). Roughly 15–20 minutes: shut off power and gas, remove the two mounting screws, transfer the spade wires, and mount the new switch in the same orientation. Verify normal operation and cycle the furnace after install.
Ships fast from stock. Fit-guaranteed for the AMVC800805DNAA and related Goodman/Amana furnace models.
