The Goodman 20269903 Auxiliary Limit Auto-Reset Switch is a genuine OEM safety component engineered for the GMV80905CXA gas furnace and other compatible Goodman and Amana models. This auxiliary limit switch continuously monitors internal temperatures and automatically opens the control circuit if the furnace exceeds its safe operating range, shutting down the burners to prevent overheating and potential heat-exchanger damage. Because it is an auto-reset design, the switch closes and restores normal operation once temperatures return to a safe level — no manual intervention required.

Specifications

Type: Auxiliary limit / high-limit safety switch
Reset: Automatic (auto-reset)
Function: Overtemperature burner shutoff
Fits: Goodman GMV80905CXA and compatible 80% AFUE furnaces
Brand: OEM Goodman / Amana

OEM vs. Generic

This is the factory OEM part, calibrated to the exact trip temperature Goodman engineers specified for the GMV80905CXA. Generic aftermarket limit switches often use different set points or lower-grade bimetal discs that can nuisance-trip or fail to protect the heat exchanger. For a safety-critical component, we strongly recommend the genuine OEM switch.

Install Difficulty

Easy (2/5) — Typically a two-wire, single-mount replacement. Always disconnect power at the breaker before servicing and confirm the part matches your unit's wiring. If your furnace repeatedly trips on limit, inspect for airflow restrictions before assuming switch failure.
