Goodman 20162904 Primary Limit Temperature Control

The Goodman 20162904 is a genuine OEM primary high-limit temperature control for the VMS80603ANAA 80% gas furnace and compatible models. Mounted on the heat-exchanger bulkhead, this snap-disc limit monitors supply-air temperature and opens the gas/ignition circuit if the furnace overheats — typically from restricted airflow, a dirty filter, or a failing blower. It is the furnace's primary overheat safety, protecting the heat exchanger from thermal stress and cracking.

OEM part number: 20162904
Type: Primary high-limit switch (auto-reset snap disc)
Contacts: Normally closed, opens on high temperature
Function: Supply-air overheat protection
Mounting: Heat-exchanger / blower bulkhead plate
Fits: Goodman VMS80603ANAA and compatible furnaces

OEM vs. Generic

The OEM 20162904 uses Goodman's exact trip and reset set points and factory mounting flange, so it seats correctly and responds at the designed temperature. Generic snap discs may have different calibration or bracket geometry, leading to nuisance lockouts or delayed protection. For a heat-exchanger safety, OEM is the confident choice.

Installation Difficulty: Easy to Moderate

Power off the furnace, disconnect the wire terminals, remove the two mounting screws, and install the replacement in the same position and orientation. If the limit continues to trip, check airflow, filter, and blower operation before assuming the part is faulty.
