The Goodman 10123529 Manual Reset Limit Switch is a genuine OEM high-temperature safety control for the AMH81005CXBA furnace and compatible Goodman/Amana models. This rollout/limit switch opens the gas-valve circuit if it senses excessive heat or flame rollout, shutting the furnace down to prevent a hazardous overheat. Because it is a manual reset device, it must be pressed to restore operation after a trip — a deliberate design that flags a real problem rather than silently cycling.
The OEM 10123529 is calibrated to the exact trip temperature your furnace's safety design requires. Generic limit switches with mismatched cut-out points can nuisance-trip or, worse, fail to protect against a genuine rollout. On a safety-critical part, always install genuine OEM.
Easy (2/5). Cut power, note wire positions, unscrew the switch from the burner box, transfer the two spade terminals, and mount the new one. A 10–15 minute job. If the switch keeps tripping, diagnose the underlying overheat (dirty filter, blocked flue, weak blower) before returning to service.
