The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM high-limit switch for Goodman and Amana AMS81005CXAD gas furnaces. Mounted on the heat exchanger bulkhead, it continuously senses supply-air temperature and opens the gas valve circuit if the furnace overheats — typically from restricted airflow such as a clogged filter, closed registers, or a failing blower. Unlike a manual rollout switch, this primary limit is auto-reset and will restore operation once temperatures return to a safe range.

Specifications

Part type: Primary high-limit temperature control
Reset: Automatic
Function: Heat-exchanger overheat protection
Fit: Goodman / Amana AMS81005CXAD and compatible models
OEM Part Number: 20162904

OEM vs. Generic

The OEM 20162904 carries the factory-calibrated trip and reset set points and the correct mounting bracket geometry. Generic limits with different set points can cause short-cycling or fail to protect the heat exchanger. For a primary safety control, OEM is strongly recommended.

Install Difficulty

Easy (2/5). Disconnect power, unplug the two wire leads, remove the mounting screws, and swap. Confirm the sensing element clears the heat exchanger and airflow path. Restore airflow issues before returning the furnace to service.

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?

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.
