Goodman 20269903 Auxiliary Limit Auto-Reset Switch

The Goodman 20269903 is a genuine OEM auxiliary limit switch engineered for the WGGE4324A045MAB gas furnace and compatible Goodman and Amana models. This auto-reset safety control monitors heat-exchanger and cabinet temperatures, opening the burner circuit if the unit overheats and automatically re-closing once temperatures return to a safe range. A failed limit switch is a common cause of a furnace that short-cycles, locks out, or refuses to fire on a call for heat.

Specifications

Type: Auxiliary temperature limit switch, automatic reset
OEM Part Number: 20269903
Fits: Goodman WGGE4324A045MAB and select Goodman/Amana furnaces
Function: Overheat safety cutout / rollout protection
Mounting: Direct bolt-on replacement, factory calibrated

OEM vs. Generic

The OEM 20269903 is factory-calibrated to the exact open/close temperatures your furnace's control sequence expects, ensuring safe, code-compliant operation. Universal aftermarket limits often carry different trip points that can cause nuisance lockouts or, worse, defeat the safety margin. For a critical safety component we recommend genuine OEM.

Install Difficulty

Easy (1 of 5). Cut power at the disconnect, disconnect the two spade terminals, remove the mounting screws, and swap in the new switch. Typically a 10–15 minute repair with a nut driver. Always de-energize the furnace before servicing.
