The genuine Goodman 20162904 Primary Limit Temperature Control is the main high-limit safety for AMEH800603BXAA gas furnaces. Mounted on the heat-exchanger bulkhead, it senses supply-air temperature and shuts off the gas valve if the furnace exceeds its safe operating range, protecting the heat exchanger and cabinet from heat damage. This auto-reset control restores operation once temperatures return to normal.

Specifications

Part number: 20162904
Part type: Primary limit temperature control
Function: High-limit overtemperature safety cutout
Reset: Automatic
Fits: Goodman & Amana AMEH800603BXAA gas furnaces

OEM vs. Generic

This OEM control is factory-calibrated to the precise trip point Goodman specifies for the AMEH800603BXAA heat exchanger and blower profile. Aftermarket limit controls with mismatched trip temperatures cause nuisance shutdowns during normal heating cycles or fail to protect the unit under fault conditions. On a primary safety control, OEM calibration is essential.

Installation Difficulty

Easy (2/5). Power down the furnace, photograph and disconnect the wiring, remove the mounting screws, and install the replacement in the identical orientation so the sensing element sits correctly in the airstream. Reconnect, restore power, and confirm a full heating cycle completes without tripping. Typical install 15 minutes.
