OEM Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a genuine primary high-limit safety switch calibrated to open at 150°F, built for the Amana AMVC80603BNCA two-stage variable-speed furnace and compatible Goodman/Amana models. Mounted on the heat exchanger or blower shelf, the primary limit monitors supply-air temperature and shuts off the gas valve if the furnace overheats — protecting the heat exchanger from cracking and preventing hazardous operation. A failed or nuisance-tripping limit is a common cause of no-heat calls and short cycling.

Specifications

Trip temperature: 150°F (auto-reset)
Part type: Primary high-limit / temperature safety switch
Fits: Amana AMVC80603BNCA and cross-compatible Goodman/Amana furnaces
OEM Part Number: 20162903
Function: Interrupts gas valve on over-temperature

OEM vs. Generic

Aftermarket limits often ship with a generic trip point or mounting bracket that doesn't match Goodman's airflow design, leading to premature nuisance trips. This OEM 20162903 is factory-calibrated to the exact 150°F setpoint and bolt pattern the AMVC80603BNCA expects — plug-and-play reliability with no recalibration.

Install Difficulty

Easy — Cut power, unplug the two spade terminals, remove two mounting screws, and swap. Typically a 10–15 minute repair. Confirm the furnace cycles fully and reaches setpoint after installation.
