Goodman 10123529 Manual Reset Limit Switch

The 10123529 is a genuine OEM manual-reset high-limit switch for Goodman DMP075-32AA gas furnaces and compatible Goodman/Amana models. This safety-critical control opens the circuit and shuts down the burners if it senses an over-temperature condition — protecting the heat exchanger and cabinet from damage caused by restricted airflow, a failed blower, or a dirty filter. The manual-reset design requires a deliberate button press to restore operation, prompting service before the furnace runs again.

OEM vs. Generic

OEM Goodman limit switches are calibrated to the exact trip and reset temperatures Goodman engineered for this furnace, ensuring the safety chain behaves as designed. Generic switches may trip at the wrong temperature, causing either nuisance lockouts or, worse, failing to protect the unit. For safety components, OEM is strongly recommended.

Installation Difficulty: Moderate

Turn off gas and power, note the wiring, unbolt the old switch from its bracket, and mount the replacement in the same location with clean spade connections. If the switch tripped, diagnose and correct the underlying overheat cause before returning the furnace to service. Technician recommended.
