The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM high-limit safety switch for the WGFM295115V5DAA two-stage 96% AFUE gas furnace. Mounted on the heat-exchanger bulkhead, it continuously monitors supply-air temperature and opens the circuit if the furnace overheats — typically from restricted airflow, a dirty filter, a failed blower, or closed registers. This prevents heat-exchanger damage and unsafe operating temperatures.

Specifications

OEM Part Number: 20162904
Type: Primary high-limit temperature control
Action: Auto-reset thermal limit (opens on rise)
Function: Over-temperature safety cutoff
Brand: Goodman
Fits: WGFM295115V5DAA furnace

OEM vs. Generic

The OEM 20162904 is factory-set to the exact trip and reset temperatures the WGFM295 heat exchanger requires. A generic limit with the wrong temperature rating or bracket geometry can trip prematurely (no heat) or too late (overheating risk). For a safety limit, the genuine Goodman part is the correct choice and keeps the furnace warranty intact.

Installation Difficulty

Easy — power down the furnace, unplug the two wire leads, remove the two mounting screws, and install the new limit in the identical position so the sensing element sits correctly in the airstream. No calibration needed.
