Goodman 10123529 Manual Reset Limit Switch

The Goodman 10123529 is a genuine OEM manual reset high-limit / rollout safety switch engineered for the Goodman ACEC800603BXAA gas furnace and compatible models. This safety control trips and shuts off the burner circuit when it detects excessive heat or flame rollout, then requires a manual press of the reset button before the furnace can fire again — protecting the heat exchanger and your home from overheating.

Specifications

Type: Manual reset bimetal limit switch
Function: High-limit / flame rollout safety cutoff
Mounting: OEM bracket-mount, direct replacement
Reset: Manual push-button
Fits: Goodman ACEC800603BXAA and compatible gas furnaces
OEM Part Number: 10123529

OEM vs. Generic

Our genuine OEM 10123529 is calibrated to Goodman's exact trip temperature, ensuring the furnace's safety logic behaves as the manufacturer intended. Generic limit switches may trip early (nuisance lockouts) or late (unsafe). For a primary safety control, we strongly recommend the OEM part.

Installation Difficulty

Easy — typically a two-wire swap and one or two mounting screws. Always shut off power and gas before service. If the switch tripped, diagnose the underlying cause (blocked flue, dirty filter, failed blower) before resetting.
