The Goodman 10123517 Manual Reset Limit Switch is a genuine OEM safety control for the Goodman GCH950453BXAC gas furnace and compatible models. Unlike an auto-reset limit, this switch latches open when it detects an overheat or flame-rollout condition and must be manually reset — forcing a technician to inspect the furnace before it can run again. That deliberate design protects against dangerous repeat faults.
This genuine Goodman OEM switch carries the exact temperature trip rating specified for this furnace. Because it guards against flame rollout — a serious safety hazard — using the correct OEM part is strongly recommended over generic substitutes with uncertain calibration.
Easy to Moderate. Mounting is simple (screws + spade terminals), but repeated tripping indicates an underlying problem (blocked flue, cracked heat exchanger, dirty burners) that must be diagnosed. Shut off power and gas first. Estimated time: 15–25 minutes. Recommend a licensed HVAC technician if the switch trips again after reset.
