Goodman 10123529 Manual Reset Limit Switch

The 10123529 is a genuine OEM manual-reset limit switch for the Goodman WFD18115S5CXCB gas furnace. This is a safety-critical high-limit / rollout switch that opens the control circuit and shuts down the burner if it senses overheating or flame rollout. Because it is a manual reset, it stays tripped until pressed — a deliberate design that forces a technician to inspect the cause before the furnace can fire again. A furnace that trips out and won't restart often needs this switch replaced.

Specifications

Type: manual-reset thermal limit / rollout switch
Action: normally closed, opens on overtemp
OEM part number: 10123529
Primary fit: Goodman WFD18115S5CXCB furnace

OEM vs. Generic

The trip temperature and reset behavior of a safety switch are not places to guess. The OEM Goodman 10123529 is calibrated to the exact cutout point the WFD18115S5CXCB engineers specified. Generic switches with a different trip rating can nuisance-trip or, worse, fail to trip when needed. For any safety-listed component, always use genuine OEM.

Install Difficulty

Easy. Two spade wires and one or two mounting screws — typically a 10–15 minute swap. Shut off power and gas first. If the switch was tripped, diagnose the overheat cause (dirty filter, blocked flue, weak blower) before returning to service.
