The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM high-limit safety switch built for the Goodman WFD195070S3BAB furnace and compatible WFD-series models. This limit control continuously monitors heat-exchanger temperature and shuts off the burners if the furnace overheats, protecting the equipment and your home from unsafe conditions. A tripped or failed limit is a leading cause of short cycling and no-heat calls, so a correct replacement restores reliable, safe operation.

Part number: 20162904
Category: Primary high-limit temperature control
Fits: Goodman WFD195070S3BAB and compatible WFD furnaces
Function: Automatic reset thermal safety cutoff
Type: Direct-fit OEM limit switch

OEM vs. Generic: This authentic Goodman control is calibrated to the exact trip and reset temperatures your furnace was engineered for. Generic or universal limits often carry different setpoints or mounting flanges, which can cause nuisance trips or fail to protect the heat exchanger. OEM ensures precise calibration and safe, warranty-compliant fitment.

Installation difficulty: Moderate. A trained technician typically swaps this limit in 20-30 minutes: cut power, remove the burner-compartment panel, disconnect the two wire leads, unscrew the mounting bracket, and install the new control in the same orientation. Because this is a safety component, verification of correct operation by a licensed HVAC professional is strongly recommended.

Trust genuine Goodman parts to keep your furnace protected. The 20162904 ships fast and installs to factory specification.
