The Goodman 20162903 Primary Limit Switch is a factory-original high-temperature safety control for the Goodman GMH951155DXAF 96% AFUE two-stage multi-position gas furnace. Mounted on the heat exchanger vestibule, this normally-closed thermal switch opens at approximately 150°F to shut off the burners if the furnace overheats — protecting the heat exchanger and preventing unsafe operation. A failed or nuisance-tripping limit switch is one of the most common causes of a furnace that fires and then short-cycles on high limit.

OEM vs. Generic

Our OEM 20162903 is the genuine Goodman-specified part with the exact trip temperature and mounting bracket for a plug-and-play replacement. The generic equivalent matches the 150°F rating and terminal spacing at a lower price — a solid choice for budget repairs where an exact OEM stamp isn't required. Both carry the same safety function.

Installation Difficulty

Easy (1/5). Disconnect power, remove two mounting screws and the two spade connectors, and reverse to install. Most techs and handy homeowners complete this in under 15 minutes. Always confirm power is off at the breaker before servicing.
