The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-limit safety control for DMP125-52AB furnaces. This normally-closed switch opens and cuts the gas valve if it senses excessive temperature or flame rollout, protecting the heat exchanger and household from overheating. Because it is a manual reset design, it stays tripped until pressed — a repeatedly tripping switch signals restricted airflow or a combustion fault that should be diagnosed. A failed or fatigued switch causes nuisance lockouts or a no-heat condition.

OEM vs. Generic

The OEM Goodman switch is calibrated to the factory trip temperature for correct, code-compliant protection. Our Generic equivalent is matched to the same trip point and terminal layout at a lower price. Because this is a safety component, verify the trip rating matches your original before installing.

Install Difficulty

Easy. Cut power, disconnect the two spade terminals, remove the mounting screws, and swap. About 10–15 minutes. Never bypass a limit switch — it is a life-safety device.
