Goodman 10123529 Manual Reset Limit Switch

The 10123529 is a genuine OEM Goodman manual reset limit (rollout) switch for the AMH80603ANBD gas furnace and compatible Goodman/Amana models. This safety control opens the ignition circuit if it senses excessive heat or flame rollout at the burner box, shutting the furnace down until an operator manually presses the reset button. A switch that will not reset, or one that trips repeatedly, must be replaced with an exact-rated OEM part — never bypassed.

Specifications

Type: Manual reset limit / rollout switch
Function: High-temperature safety cutout
Reset: Manual push-button
Fits: Goodman / Amana AMH80603ANBD and compatible furnaces
OEM Part Number: 10123529

OEM vs. Generic

OEM 10123529 switches are calibrated to the exact trip temperature specified for this furnace. Generic switches may carry a different set point, which can cause nuisance trips or, worse, fail to protect against rollout. Because this is a life-safety device, OEM is strongly recommended.

Install Difficulty

Easy (2/5) — Two mounting screws and two spade terminals. Kill power at the disconnect first. Most installs take under 20 minutes. If a new switch trips again, diagnose the rollout cause before running the furnace.
