The Goodman 20162903 Primary Limit Switch is a genuine OEM high-limit safety control rated to open at 150°F, used on the Amana AMH951155DXAD 95%+ AFUE gas furnace. Mounted on the heat exchanger or blower deck, it monitors supply-air temperature and cuts power to the gas valve if the furnace overheats — protecting the heat exchanger from cracking and preventing a fire hazard.

Specifications

Part Number: 20162903
Type: Primary high-limit switch
Trip Temperature: 150°F (normally closed, opens on rise)
Reset: Automatic
Function: Overheat / high-limit safety cutout
Fits: Amana / Goodman AMH951155DXAD and compatible furnaces

OEM vs. Generic

Our OEM 20162903 is calibrated to Goodman's exact 150°F trip point and uses the correct bracket geometry for a proper seat against the airstream. Generic limits with an approximate trip temperature can nuisance-trip (short cycling on heat) or, worse, fail to open at the design temperature — defeating the safety function. On a life-safety control, OEM calibration matters.

Installation Difficulty

Moderate (2/5). Power down the furnace, remove the two mounting screws, unplug the spade terminals, and install the replacement in the same orientation. A multimeter helps confirm continuity before and after. Typically a 15–20 minute job for a handy owner.

If your furnace is locking out on a repeated limit-open code, also check airflow, the filter, and blower operation. Need help? info@nationalhvacparts.com.
