The Goodman/Amana 20269903 is a genuine OEM auxiliary limit switch designed as a factory-direct replacement for the AMV80704BXBB gas furnace and other compatible Goodman and Amana models. This is a safety-critical high-limit control that opens the circuit if the furnace overheats and automatically resets once safe operating temperatures return, protecting the heat exchanger and blower assembly from thermal damage.

Specifications

Type: Auxiliary high-limit switch, automatic reset
Function: Overheat protection / secondary limit control
Fits: Goodman & Amana furnaces including AMV80704BXBB
OEM Part Number: 20269903

OEM vs. Generic

The genuine OEM 20269903 is calibrated to the exact trip temperature your furnace's control board expects, ensuring proper cycling and safety compliance. Generic aftermarket limit switches may trip at incorrect temperatures, causing nuisance shutdowns or, worse, failing to protect the unit. For a safety component, OEM is strongly recommended.

Installation Difficulty: Easy

Rated Easy — a typical replacement takes 10–15 minutes with basic hand tools. Always disconnect power at the breaker before servicing. Remove the two mounting screws, disconnect the spade terminals, and install the new switch in the same orientation. If you are not comfortable working around gas heating equipment, consult a licensed HVAC technician.
