Goodman 10123533 Manual Reset Limit Switch

Protect your Goodman GMH950905DXAE furnace from dangerous overheating with this genuine OEM 10123533 manual reset limit switch. This high-temperature safety cutout opens the control circuit and shuts the burners off if the heat exchanger or supply plenum exceeds its safe operating temperature — typically caused by restricted airflow, a failed blower, or a clogged filter. The manual reset design requires a technician to physically press the button, ensuring the underlying fault gets diagnosed rather than repeatedly auto-cycling on a hazardous condition.

Part number: 10123533
Type: Manual reset high-limit safety switch
Function: Over-temperature burner cutout
Fits: Goodman GMH950905DXAE
Reset: Push-button manual (non-auto)

OEM vs. Generic

Limit switches are rated to a specific trip temperature. A generic switch with the wrong set point can either trip prematurely and kill heat on normal operation, or fail to open when the furnace truly overheats — defeating the safety entirely. This OEM switch is matched to the exact temperature rating and terminal layout the GMH950905DXAE requires.

Install Difficulty: Easy (2/5)

A 15–20 minute repair. Disconnect power, note the wiring, remove the mounting screws, and transfer the spade terminals to the new switch in the same orientation on the heat-exchanger panel. Critically — before returning to service, diagnose why it tripped (dirty filter, blocked returns, weak blower). Replacing the switch without fixing the root airflow cause will only trip it again. Recommended for confident DIYers or an HVAC technician.

Genuine Goodman safety component — exact fit for the GMH950905DXAE.
