The Goodman 20162903 Primary Limit Switch is a genuine OEM 150°F high-limit safety control for the Goodman GMV951155DXBA 96% AFUE variable-speed gas furnace and compatible GMV/GCV models. Mounted on the heat-exchanger deck, this switch continuously monitors supply-air temperature and shuts off the burners if the furnace overheats — protecting against restricted airflow and a cracked heat exchanger.

When a dirty filter, closed dampers, or a failing blower let temperatures climb, the 150°F switch opens and cuts the gas valve, then automatically resets once temperatures fall back to a safe range. Short-cycling on the limit is a classic sign of an airflow problem or a worn limit switch that trips too early.

Part number: 20162903 (OEM Goodman)
Type: Primary high-limit switch (auto reset)
Trip point: 150°F
Contacts: Normally closed (opens on overheat)
Fits: Goodman GMV951155DXBA and compatible furnaces

OEM vs. Generic: The genuine 20162903 is set to Goodman's exact 150°F trip temperature and mounting-bracket dimensions, so it protects the heat exchanger without nuisance trips. Generic limits with slightly different set points cause premature shutdowns or, worse, fail to protect. For a safety-critical control, choose OEM.

Installation difficulty: Easy — usually two screws and two spade terminals, about 10 minutes with a nut driver. Replace filters and confirm proper airflow first, since a good limit switch trips for a reason. Shut off gas and power before servicing.
