Goodman 20162904 Primary Limit Temperature Control

The Goodman 20162904 is a genuine OEM primary high-limit temperature control designed for the Amana/Goodman AMS80804BXAA gas furnace. This safety switch continuously monitors heat-exchanger and plenum temperature; if airflow is restricted or the furnace overheats, it opens the circuit and shuts down the gas valve to prevent heat-exchanger damage and unsafe operating conditions. It automatically resets once temperatures return to a safe range.

Specifications

Type: Primary high-limit / auto-reset snap-disc control
Function: Over-temperature safety shutoff
Fits: Amana/Goodman AMS80804BXAA and compatible furnaces

OEM vs. Generic

The OEM 20162904 is calibrated to the precise cut-out temperature Goodman engineered for this furnace's heat exchanger. Generic limit switches with the wrong trip point can either nuisance-trip during normal operation or fail to protect against genuine overheating. Choosing the factory part guarantees correct safety response and preserves your warranty.

Installation Difficulty

Easy to Moderate. Disconnect power, remove two mounting screws and the wire terminals, and install the new switch in the same orientation. Basic hand tools required; no gas work involved.
