OEM Goodman Auxiliary Limit Switch (Light Blue) for AMEC961004CNAA — 0130F00038

The Goodman 0130F00038 auxiliary limit switch (identified by its light blue color code) is a genuine OEM secondary safety control for the AMEC961004CNAA gas furnace. It backs up the primary limit by monitoring temperature at a secondary location — typically near the blower compartment — and opens the control circuit on an overheat the primary might not catch, such as a blower-motor failure. The color coding identifies its specific trip temperature, so matching it exactly is critical.

Specifications

• Type: Auxiliary / secondary high-limit switch
• Color code: Light blue (denotes factory trip temperature)
• Action: Opens on overtemperature to shut down the furnace
• Normally closed 24V control-circuit contacts

• OEM Part Number: 0130F00038

OEM vs. Generic

The light-blue OEM 0130F00038 is calibrated to the exact set point Goodman specifies for this position. Substituting a switch with a different color code — even one that physically fits — changes the trip temperature and can compromise the furnace's layered safety design. For an auxiliary safety limit, always match the OEM part and color.

Installation Difficulty

Moderate (2/5). Turn off power at the breaker, open the appropriate access panel, disconnect the spade terminals, remove the mounting screws, and install the new switch in the same location. If it tripped, find and correct the overheat cause before restarting. Professional service recommended if you are unsure of placement.
