Goodman 20162904 Primary Limit Temperature Control

The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM high-limit safety switch for the WGFD295070V4CAA gas furnace. This control monitors heat-exchanger and plenum temperature, cutting power to the gas valve if the furnace overheats — a critical safety device that prevents cracked heat exchangers, tripped boards, and unsafe operation. A failed limit switch is a common cause of a furnace that short-cycles, blows cold air, or won't fire at all.

OEM vs. Generic

This genuine Goodman OEM limit is factory-calibrated to the exact trip temperature and mounting footprint for the WGFD295070V4CAA. Generic limits with the wrong cut-out temperature can nuisance-trip or, worse, fail to protect the heat exchanger. For a safety-rated component, OEM is strongly recommended.

Installation Difficulty

Moderate (2 of 5). Two mounting screws and two spade connectors, but correct orientation and clean electrical contact are essential. Shut off power and gas first. Professional installation recommended.
