The Goodman 20162904 Primary Limit Temperature Control is a genuine OEM high-limit switch for AMH81005CXBD gas furnaces and compatible Goodman/Amana models. Mounted on the heat exchanger / blower bulkhead, it continuously senses supply-air temperature and shuts off the gas valve if the furnace overheats — typically from restricted airflow, a dirty filter, or a failed blower. It is an auto-reset control that re-closes once temperatures return to a safe range.

Specifications

Type: Primary auto-reset high-limit temperature control
Function: Overheat safety cutout for the gas valve circuit
Mounting: OEM bulkhead flange with insertion probe/disc
Terminals: Spade connectors
Fits: AMH81005CXBD and related Goodman/Amana furnaces

OEM vs. Generic

This control's cut-out and cut-in temperatures are matched to the AMH81005CXBD's heat-exchanger design. OEM 20162904 guarantees the correct set point and probe length. Generic limits with the wrong trip temp risk both nuisance shutdowns and unsafe over-temperature operation, which is why OEM is strongly recommended for this safety-critical part.

Install Difficulty

Moderate — Shut off gas and power, remove the mounting screws, withdraw the sensing probe from the airstream, transfer the wiring, and install the new control in the same orientation. Confirm airflow issues (filter, blower) are resolved so the new limit isn't tripped by the same underlying fault.

Frequently Asked Questions

Does this Limit Control fit my Goodman AMH81005CXBD — 20162904?

Yes. This is the factory-specified OEM limit control for the Goodman AMH81005CXBD — 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 AMH81005CXBD — 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.
