The Goodman 20162904 primary limit temperature control is a genuine OEM high-limit safety and airflow-monitoring control for VMES800603AXAA gas furnaces and compatible Goodman/Amana models. Mounted on the heat-exchanger bulkhead, the primary limit senses supply-air temperature and opens the gas valve circuit if the furnace overheats due to restricted airflow, a dirty filter, or a stalled blower. It is the furnace's main line of thermal defense.
The OEM Goodman 20162904 is factory-calibrated to the exact trip and reset temperatures Goodman specified for this cabinet, along with the correct probe length and mounting footprint. Generic substitutes with different set points risk nuisance lockouts or delayed protection. For this safety-critical control, OEM is the right choice.
Replacement requires removing the control panel or blower access, unscrewing the limit from the bulkhead, transferring the wiring, and seating the new control with the probe correctly positioned in the airstream. After install, confirm the furnace reaches full heat without tripping and verify temperature rise is within the nameplate range. Recommended for a licensed HVAC professional.
