Goodman 20162906 M4 Primary Limit Switch

The Goodman 20162906 is a genuine OEM primary (high) limit switch engineered for the GKS91155DXAE gas furnace and compatible Goodman/Amana 90%+ AFUE models. This safety control continuously monitors heat-exchanger temperature and interrupts the burner circuit if the furnace overheats — protecting the heat exchanger, blower assembly, and your home from unsafe operation. A failing limit switch commonly causes short-cycling, no-heat calls, or a furnace that locks out on the control board.

Type: Primary high-limit safety switch (M4 series)
Function: Automatic-reset thermal cutoff
Fits: Goodman GKS91155DXAE and compatible 90%+ furnaces

OEM vs. Generic

The OEM 20162906 is factory-calibrated to the exact trip temperature specified for your furnace, ensuring correct safety response and preserving equipment warranty. Universal or generic limit switches may trip at incorrect temperatures, leading to nuisance lockouts or delayed shutoff. For a safety-critical component, OEM is strongly recommended.

Installation Difficulty

Easy to Moderate. Replacement typically takes 20–30 minutes and requires disconnecting power, removing two mounting screws, and transferring the wire leads. Always shut off gas and electrical power before servicing. If unsure, consult a licensed HVAC technician.

Ships fast and backed by our exact-fit guarantee.
