Goodman 20162903 Primary Limit Switch (150°F)

The Goodman 20162903 is a genuine OEM primary high-limit switch designed for the AMEH800805DNAA furnace and compatible Goodman/Amana gas furnaces. This safety-critical component continuously monitors heat-exchanger temperature and opens the circuit if the furnace exceeds its safe operating limit — shutting down the burners to prevent overheating, cracked heat exchangers, and fire hazards. A failed limit switch causes short-cycling, no-heat lockouts, or unsafe operation.

Specifications

Cutout temperature: 150°F (primary high-limit)
Type: Automatic-reset bimetal limit switch
OEM Part Number: 20162903
Fits: AMEH800805DNAA and compatible Goodman/Amana furnaces
Factory-calibrated trip point
Direct plug-and-mount replacement

OEM vs. Generic

Limit switches are life-safety devices, and trip temperature must be exact. Aftermarket switches may trip early (nuisance shutdowns) or late (dangerous overheating). This OEM Goodman 20162903 is calibrated to the precise 150°F setpoint the AMEH furnace was engineered around — the right call for any safety component.

Installation Difficulty

Easy to Moderate. Typically two mounting screws and a pair of push-on terminals. Cut power at the breaker first, note wire positions, and confirm the switch part number matches. Estimated time: 15–20 minutes.

Shut off electrical power before servicing. Never bypass a limit switch. If unsure, consult a licensed HVAC professional.
