Goodman 10123529 Manual Reset Limit Switch

The 10123529 is a genuine OEM Goodman manual-reset high-limit / rollout safety switch for the ADSS800804BXAB gas furnace. This is a normally-closed thermal safety that opens the ignition/gas-valve circuit if it senses excessive temperature — typically from a blocked flue, failed blower, or flame rollout. Unlike an auto-reset limit, the manual version requires pressing the reset button after the fault is cleared, which is by design a signal to inspect the furnace before returning it to service.

Specifications

Part number: 10123529
Type: Manual reset high-limit / rollout thermal switch
Contacts: Normally closed, opens on temperature rise (SPST)
Brand: Goodman (also fits Amana equivalents)
Primary fit: ADSS800804BXAB gas furnace
Reset: Manual push-button

OEM vs. Generic

Safety limits must trip at the exact temperature Goodman engineered for this furnace. The OEM 10123529 carries the correct trip point, mounting bracket, and terminal spacing. Substituting a generic switch with a different rating can cause nuisance trips or, worse, allow an unsafe over-temperature condition. Always use the OEM safety control.

Installation Difficulty

Moderate (2/5). Two spade terminals and one or two mounting screws. Disconnect power before servicing. Because this is a combustion safety device, verify correct operation after replacement — when unsure, use a licensed HVAC technician.
