Goodman 20162906 M4 Primary Limit Switch

Protect your Goodman GKS91155DXAB furnace from overheating with the genuine OEM 20162906 M4 primary limit switch. Mounted on the heat exchanger/blower deck, this primary high-limit control continuously monitors supply-air temperature and de-energizes the gas valve if airflow is restricted or temperatures exceed the safe threshold. It is the furnace's main over-temperature safeguard, preventing heat-exchanger damage and unsafe operation caused by dirty filters, closed registers, or blower failure.

Specifications

Type: M4 primary high-limit switch (SPST, normally closed)
Function: Primary over-temperature safety cutout
Reset: Manual reset
Mounting: OEM heat-exchanger/blower-deck bracket
Fits: Goodman GKS91155DXAB and compatible models
OEM Part Number: 20162906

OEM vs. Generic

The genuine OEM 20162906 is factory-calibrated to the exact M4 trip temperature Goodman specifies for the GKS91155DXAB. Aftermarket limits with different ratings can nuisance-trip or fail to protect at the correct threshold. As the primary safety limit, the OEM-calibrated part is the reliable choice.

Installation Difficulty

Easy (2/5) — Turn off power and gas. Disconnect the two leads, remove the mounting screws, install the new limit in the same orientation, and reconnect. Investigate any repeated trips (airflow, filter, blower) before returning to service. Professional service recommended if the fault is unclear.
