The Goodman 10123537 gray manual reset limit switch is a high-temperature safety device for the AMVC950704CXAA furnace. Its distinct gray body denotes a specific factory trip-temperature calibration, so it is important to match the exact part number rather than substituting a similar-looking switch. It cuts burner operation on an overheat condition — caused by dirty filters, blocked returns, or blower failure — and holds lockout until manually reset.
The genuine Goodman OEM gray switch is factory-set to the correct cutout temperature for its mounting location on this furnace. Because color and part number indicate calibration, generic or wrong-color substitutes can trip early or fail to protect the heat exchanger. OEM guarantees the right setpoint and fit.
Easy to Moderate (~20 minutes). Cut power, unplug the two spade terminals, remove the mounting screws, and install the replacement in the same position and orientation. Verify continuity with a meter. As a safety part, always diagnose and correct the cause of any trip, and consult a licensed HVAC technician if unsure.
