Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a genuine OEM primary high-limit safety switch calibrated to open at 150°F, built as a direct-fit replacement for the GCH950904CXAD gas furnace. Mounted on the heat exchanger, this normally-closed thermal switch continuously monitors supply-air temperature and shuts off the burners if the furnace overheats — protecting the heat exchanger from cracking and preventing a potential fire hazard. A failed limit switch is a common cause of short cycling, no-heat calls, or a furnace that runs the blower but never fires.

Specifications

  • OEM Part Number: 20162903
  • Trip Temperature: 150°F (auto-reset)
  • Type: Primary high-limit safety switch, normally closed
  • Compatible Model: Goodman GCH950904CXAD
  • Function: Overheat protection / burner cutout
  • Brand: Genuine Goodman OEM

OEM vs. Generic

The genuine Goodman switch is factory-calibrated to the exact 150°F trip point and mounting footprint your furnace's control board expects. Generic switches may carry a different setpoint or bracket geometry, leading to nuisance trips or, worse, failure to trip. For a life-safety component, we recommend genuine OEM.

Installation Difficulty

Easy to Moderate — Power off the furnace, disconnect the two spade terminals, remove two mounting screws, and install the replacement. Most handy homeowners can complete it in 15–20 minutes, but confirm the correct temperature rating before installing.
