OEM Goodman 20162904 Primary Limit Temperature Control

The 20162904 primary limit temperature control is the main high-limit safety switch for the Goodman/Amana AMEC960803BNAC gas furnace. It continuously monitors supply-air temperature at the heat exchanger and interrupts the gas valve if the furnace overheats — protecting the heat exchanger from cracking and preventing a fire hazard. A furnace that short-cycles on heat, trips the burner shortly after ignition, or throws a limit-open fault code is often signaling a failed or drifting primary limit.

Specifications

Part type: Primary (high) limit temperature control
Function: Automatic-reset thermal safety switch
Circuit: Normally closed, opens on overtemperature
Fits: Goodman / Amana AMEC960803BNAC gas furnace
Position: Heat exchanger / supply-air limit location
OEM part number: 20162904

OEM vs. Generic

This is a genuine OEM Goodman control calibrated to the exact trip point specified for this furnace platform. Universal or generic limit switches often carry a different set point or mounting footprint, which can cause nuisance trips or fail to protect the heat exchanger correctly. Because this part governs a life-safety function, we recommend matching OEM specification rather than substituting a generic.

Installation Difficulty

Rating: Easy–Moderate (2 of 5). Replacement is a single mounting-plate swap with two spade terminals — typically 15–20 minutes for a competent DIYer. Always shut off gas and 120V power at the disconnect before servicing. Gas-fired heating repairs should be verified by a licensed HVAC technician.
