The Goodman 20162903 Primary Limit Switch is a genuine OEM high-temperature safety control rated to trip at 150°F, designed for the GKS90703BXAC gas furnace and compatible Goodman/Amana models. Mounted on the heat exchanger or blower housing, the primary limit switch monitors supply-air temperature and shuts off the burners if the furnace overheats — a critical safety function that prevents heat exchanger damage and fire risk. A failed limit switch is a common cause of short-cycling, no-heat calls, or a furnace that runs the blower but won't fire.

Specifications

  • OEM Part Number: 20162903
  • Part Type: Primary (High) Limit Switch
  • Trip Temperature: 150°F
  • Function: Auto-reset high-limit safety
  • Fits Model: GKS90703BXAC (and compatible Goodman furnaces)

OEM vs. Generic

The genuine OEM Goodman switch is calibrated to the exact 150°F trip point specified for this furnace. Generic limit switches with the wrong temperature rating or mounting flange can cause nuisance trips or, worse, fail to protect the unit. Matching the OEM trip point is essential for safe operation.

Installation

Difficulty: Easy (2/5). Power down the furnace, disconnect the two spade terminals, remove the mounting screws, and install the new switch in the same orientation. About 15 minutes with a nut driver. Verify heat cycle completes normally after installation.

Common symptoms: unusual noises, intermittent operation, complete failure, or visible damage. Visit our diagnostic hub for symptom-based troubleshooting.
Is this limit switch compatible with Bryant or Payne too?
