The Goodman 20162903 Primary Limit Switch (150°F) is a genuine OEM high-limit safety control for the GMH950704CXAF 96% AFUE two-stage gas furnace. Mounted on the heat exchanger or blower deck, this temperature-sensing switch opens the control circuit if supply-air temperature exceeds its 150°F setpoint — protecting the heat exchanger from overheating due to restricted airflow, a dirty filter, or a failed blower. It is an auto-reset device that recloses once temperatures return to normal.

Part number: 20162903
Trip temperature: 150°F setpoint
Type: Primary high-limit switch, normally closed
Reset: Automatic (recloses on cool-down)
Fits: Goodman GMH950704CXAF and compatible furnaces
Function: Heat-exchanger overheat protection

OEM vs. Generic: The OEM 20162903 is calibrated to Goodman's exact 150°F trip point and matches the factory bracket and terminal layout. Generic limits with a different setpoint can cause nuisance shutdowns or fail to protect the heat exchanger. For a primary safety control, OEM is strongly recommended.

Install difficulty: Easy — 2 out of 5. Two mounting screws and two quick-connect terminals; note the original orientation before removal. Shut off gas and power before servicing. If the limit trips repeatedly, check airflow and the filter, and consult a licensed technician.
