The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM safety control for the Goodman GMP100-5 furnace. This high-limit switch monitors heat-exchanger and burner temperatures and cuts power if the furnace overheats or a flame rollout occurs. Because it is a manual reset device, it must be physically reset after a trip — a deliberate design that flags a real safety fault (blocked venting, restricted airflow, or overheating) rather than silently cycling.

OEM vs. Generic

The OEM Goodman switch guarantees the exact trip temperature and mounting for the GMP100-5 — critical for a safety component. Our Generic equivalent matches the trip point and terminal style at a lower price. For safety controls, we recommend OEM whenever possible. Important: if this switch has tripped, diagnose and correct the root cause (airflow, venting, overheating) before returning the furnace to service.

Installation Difficulty

Rating: Easy (1/3). The switch typically mounts with two screws and quick-connect terminals. Disconnect power before servicing. Because this protects against overheating and rollout, have a qualified technician confirm the underlying fault.

In stock and ready to ship. Fit-verified for the GMP100-5.
