Goodman 20269903 Auxiliary Limit Switch (Auto Reset)

The Goodman 20269903 Auxiliary Limit Auto-Reset Switch is a genuine OEM safety control for the AMV80703BXA furnace. This normally-closed thermal cutout monitors temperature in a secondary location (such as the blower or rollout area) and opens the circuit if it detects an overheat condition, shutting down the furnace to prevent damage. As an auto-reset device, it re-closes automatically once temperatures return to a safe range.

Specifications

OEM Part Number: 20269903
Type: Auxiliary limit switch, auto-reset (SPST, normally closed)
Function: Overheat / high-temperature safety cutout
Reset: Automatic (self-resetting)
Compatibility: Goodman AMV80703BXA furnace

OEM vs. Generic

The OEM 20269903 is calibrated to Goodman's exact open/close trip temperatures for the AMV80703BXA. Because this is a safety component, an incorrectly rated generic switch can nuisance-trip or, worse, fail to trip at the correct temperature. Always use the OEM-spec part for safety-critical controls.

Installation

Difficulty: Moderate (2/5). Requires disconnecting power, removing two spade wire terminals, and unscrewing the mounting bracket. Basic multimeter continuity testing is recommended to confirm operation. If you're unsure, consult a licensed HVAC technician — this is a safety device.
