The Goodman 20162906 M4 Primary Limit Switch is a genuine OEM high-temperature safety control for the GKS91155DXAC gas furnace and related Goodman and Amana models. This normally-closed thermal switch monitors heat-exchanger and plenum temperature; if the furnace overheats due to a dirty filter, blocked ductwork, or blower failure, the limit opens and shuts off the burners to prevent damage and fire hazard. A failed or drifted limit switch causes short-cycling, no-heat lockouts, or a furnace that runs the blower continuously.

Specifications

OEM Part Number: 20162906
Type: M4 Primary High-Limit Switch (auto-reset thermal)
Configuration: Normally closed, opens on temperature rise
Fits Model: GKS91155DXAC (and compatible Goodman/Amana furnaces)
Function: Overheat safety / burner cutout
Equipment: Gas Furnace

OEM vs. Generic

This OEM limit switch is calibrated to the precise cut-out and cut-in temperatures Goodman specified for your heat exchanger. Generic "universal" limits often have the wrong trip point or mounting flange, leading to premature tripping or, worse, failure to protect the unit. Choosing OEM keeps the factory safety margin intact and protects any remaining equipment warranty.

Installation Difficulty: Easy

Rated Easy, roughly 15–20 minutes. Cut power at the disconnect, remove the two mounting screws on the burner/heat-exchanger panel, disconnect the two spade wire terminals, and install the replacement in the same orientation. Restore power and confirm a normal heat cycle. Work should be performed by a qualified HVAC technician following all local codes.
