Goodman 20269903 Auxiliary Limit (Auto-Reset)

The 20269903 is a genuine Goodman/Amana auto-reset auxiliary high-limit switch built for the AMV80704BXA 80% AFUE multi-position gas furnace. This normally-closed thermal control monitors temperature in the blower/burner area and opens the circuit if it detects an overheat condition, shutting down the gas valve to protect the heat exchanger and cabinet. Because it is auto-reset, the switch re-closes automatically once temperatures return to a safe range — restoring normal operation without manual intervention.

Specifications

OEM Part Number: 20269903
Type: Auxiliary high-limit, snap-disc
Reset: Automatic
Contacts: Normally closed (opens on temperature rise)
Mount: Factory bracket / snap-in furnace fit
Fits: AMV80704BXA and compatible Goodman/Amana furnaces

OEM vs. Generic

The OEM 20269903 is calibrated to the furnace's exact trip and reset temperatures and uses the correct terminal and bracket geometry for a true drop-in fit. Generic snap-discs may trip early (nuisance no-heat calls) or late (safety risk) and often need wiring adapters. For a safety limit, match the OEM calibration.

Installation Difficulty

Easy — disconnect power, unplug the two spade terminals, remove the mounting screws, and install the replacement in the same orientation. A typical repair takes under 15 minutes for a service tech.
