The genuine Goodman/Amana 0130F00038 Auxiliary Limit Switch (identified by its light blue housing) is the OEM secondary over-temperature safety control for the AMES800603BNAA gas furnace and compatible Goodman/Amana models. This auxiliary limit provides backup protection to the primary limit, opening the control circuit to shut down the burners if an abnormal temperature or heat rollout condition is detected in its zone of the furnace.
The light-blue color code corresponds to a precise factory trip temperature — installing a switch with the wrong rating (a different color) can either fail to protect the furnace or cause nuisance trips. The OEM 0130F00038 guarantees the correct set point and mounting fit. For a safety-critical limit, always match the exact OEM part.
Easy — Typically two screws and two spade terminals. Disconnect power at the furnace first. If the switch has tripped, have a technician determine why (blocked flue, failed blower, or rollout) before returning the unit to service.
Protect your furnace and family with a genuine Goodman/Amana auxiliary limit switch.
