Goodman 20162904 Primary Limit Temperature Control

The Goodman 20162904 is the genuine OEM primary high-limit temperature control for the Amana/Goodman AMH81005CXBC gas furnace and compatible 80% AFUE models. Mounted on the heat exchanger bulkhead, this safety switch monitors supply-air temperature and de-energizes the gas valve if the furnace overheats — protecting the heat exchanger, blower, and your home from unsafe operating conditions. A failed or drifting limit control is a common cause of short-cycling, intermittent no-heat calls, and lockouts.

Specifications

Part type: Primary high-limit temperature control (auto-reset)
Fits: Amana/Goodman AMH81005CXBC and related 80% single-stage furnaces
Function: Overheat safety cutout for gas valve / blower circuit
Connection: OEM spade terminals, factory-calibrated trip point
Brand: Genuine Goodman / Amana OEM

OEM vs. Generic

Our genuine Goodman 20162904 arrives factory-calibrated to the exact trip and reset temperatures your furnace board expects, so the safety chain behaves as engineered. Universal aftermarket limits often require guessing the temperature rating and can trip early or fail to protect the heat exchanger. For a safety-critical component, OEM is the right choice.

Install Difficulty

Easy (1 of 5). Cut power at the furnace switch, unplug the two spade wires, remove the mounting screws, swap in the new control, and reconnect. Typically a 10–15 minute repair with a nut driver. Always verify furnace operation and cycle the burners after replacement.
