Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a genuine OEM primary high-limit switch engineered for the Amana / Goodman AMH80904BXCB gas furnace and compatible 80% AFUE models. This normally-closed thermal safety control opens the burner circuit when the heat-exchanger plenum temperature exceeds its 150°F cutout point, shutting off gas and protecting your furnace from dangerous overheating caused by a dirty filter, blocked ductwork, or a failing blower.

Specifications

Cutout temperature: 150°F (auto-reset)
Type: Primary high-limit / plenum switch
Configuration: Normally closed (opens on temperature rise)
Mounting: Furnace heat-exchanger panel
Fits: Amana & Goodman AMH80904BXCB and related 80% single-stage furnaces

OEM vs. Generic

This is the factory OEM part — calibrated to the exact trip point Goodman engineered for this furnace. Generic equivalents may carry a similar temperature rating but can vary in reset behavior and mounting fit. For a safety-critical control, we recommend the OEM switch to guarantee proper cutout timing and code compliance.

Installation Difficulty

Easy (2/5). Two mounting screws and two spade terminals. Always shut off power and gas before servicing. A basic multimeter check for continuity confirms the diagnosis. Most homeowners with mechanical aptitude can replace this in under 20 minutes; when in doubt, consult a licensed HVAC technician.
