The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM high-limit safety switch for the GKS90904CXAH gas furnace and compatible Goodman/Amana models. Mounted on the heat-exchanger bulkhead, it continuously senses supply-air temperature and cuts the gas valve if airflow is lost or the exchanger overheats — protecting against cracked heat exchangers and fire hazards. Unlike the manual-reset auxiliary switch, this primary limit typically auto-resets once temperatures return to a safe range.

Specifications

OEM Part Number: 20162904
Type: Primary high-limit temperature control
Reset: Automatic (temperature-sensing)
Function: Supply-air overtemperature burner cutoff
Fits: Goodman GKS90904CXAH and compatible furnaces
Brand: Goodman / Amana OEM

OEM vs. Generic

The OEM primary limit is factory-calibrated to the exact open/close temperatures and features the correct sensing-element length and mounting flange for this furnace. Generic substitutes with the wrong trip point or probe depth cause repeated lockouts or fail to protect the exchanger. For a primary safety control, OEM is the only recommended option.

Installation Difficulty

Moderate — power off at the breaker, remove the blower/burner panel, unscrew the mounting flange, transfer the two wire leads, and reseat the sensing element in the airstream. About 20–30 minutes for a competent DIYer; a licensed technician is advised if you are unsure. Verify furnace cycles and limits correctly after install.

Frequently Asked Questions

Does this Limit Control fit my Goodman GKS90904CXAH — 20162904?

Yes. This is the factory-specified OEM limit control for the Goodman GKS90904CXAH — 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 GKS90904CXAH — 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.
