The Goodman 0130F00038 Auxiliary Limit Switch (light-blue color code) is a genuine OEM secondary safety limit for the Amana/Goodman AMEC960803BNAD gas furnace and compatible models. This auxiliary limit provides an additional layer of over-temperature protection beyond the primary limit, opening the control circuit if abnormal heat builds up in the blower or burner area.
The color code is critical — the light-blue OEM 0130F00038 is factory-set to a specific trip temperature. Substituting a generic limit with the wrong rating defeats the safety design and can cause either nuisance trips or failure to protect the appliance. Always match the OEM color/rating for auxiliary limits.
Easy. Disconnect power, remove two mounting screws, transfer the two wire leads, and mount the replacement. About 10–15 minutes for most homeowners.
