Goodman 20162904 Primary Limit Temperature Control

The Goodman 20162904 is a genuine OEM primary limit temperature control engineered for the WFD195070S4CAB gas furnace and compatible Goodman/Amana models. This high-limit safety switch continuously monitors heat exchanger temperature and shuts off the burners if the furnace overheats, protecting your equipment and your home. A failing limit control is a common cause of short-cycling, no-heat calls, and nuisance lockouts — replacing it with a factory part restores reliable, safe operation.
