The Goodman 20162904 Primary Limit Temperature Control is the genuine OEM high-limit switch that protects the Amana/Goodman AMS81005CXAB gas furnace from overheating. Mounted on the heat-exchanger bulkhead, it senses supply-air temperature and opens the circuit to the gas valve if the plenum gets too hot — typically the result of restricted airflow from a dirty filter, closed registers, or a failing blower. Once the furnace cools, this auto-reset control restores operation automatically.

Genuine OEM Goodman / Amana part number 20162904
Primary (main) high-limit / auto-reset temperature control
Factory-calibrated trip and reset temperatures — no field adjustment
Direct fit for AMS81005CXAB and compatible 80% AFUE furnaces
Snap-disc design with quick-connect terminals

OEM vs. Generic: The trip temperature and disc calibration are matched to this furnace's heat exchanger and airflow design. A generic limit with the wrong set point can either trip prematurely (short-cycling and no heat) or fail to protect the heat exchanger. For proper, safe operation, the OEM control is the right choice.

Install difficulty: Easy (2/5). Usually two mounting screws and two spade terminals — about 15 minutes for a technician or confident DIYer. Cut power and gas before servicing, and confirm airflow is not the root cause of the original trip.

Frequently Asked Questions

Does this Limit Control fit my Goodman AMS81005CXAB — 20162904?

Yes. This is the factory-specified OEM limit control for the Goodman AMS81005CXAB — 20162904. It is a direct drop-in replacement that fits without modification. Always verify the model number on your equipment nameplate before ordering.

How do I replace the limit control on my Goodman AMS81005CXAB — 20162904?

Difficulty: Advanced (1–2 hrs)
Step 1: Turn off breaker. Step 2: PHOTOGRAPH all wire connections before touching anything. Step 3: Label each wire with tape. Step 4: Disconnect all wires, remove old board. Step 5: Mount new board, reconnect all wires matching your photo exactly. Step 6: Restore power and test all modes. Exact part number match is critical.

My HVAC system is completely dead. What could be wrong?

Completely dead HVAC (no LED on board) = failed control board or blown fuse. Check board fuse first (3A or 5A, costs $1–$5). If fuse is good and board has power but no LED, board is dead. Always photograph wiring before replacing.

Is this limit control compatible with Bryant or Payne too?

Many Goodman parts are cross-compatible with Bryant and Payne since all three brands are manufactured by Carrier Global Corporation. The same physical part is often used across brand labels with different model numbers. To verify: check your Bryant or Payne equipment service manual for cross-compatible part numbers, or email info@nationalhvacparts.com with your model number.

Should I use OEM or aftermarket for my Goodman limit control?

OEM essential. Control boards are model-specific with precise firmware and connector layouts. Aftermarket boards rarely match all functions and can cause intermittent failures or safety issues. Always match the exact OEM part number.
