The Goodman 0130F00038 is a genuine OEM auxiliary limit switch built for the ADSS800403AXAD furnace and compatible Goodman/Amana equipment. This light-blue-coded secondary safety control provides an additional layer of overheat protection beyond the primary limit, opening the control circuit if abnormal temperatures are detected in its mounting location. The color code identifies its specific factory trip calibration.
The genuine OEM 0130F00038 is pre-set to Goodman's specified trip temperature and matches the original mounting bracket exactly. Because it is a safety device, we do not recommend substituting a generic switch with an unverified calibration — always match the light-blue color code.
Easy (2/5). Removes with two screws and slip-on spade terminals. Disconnect furnace power first and verify the blue color code against the failed part before installing.
