Genuine Goodman 20162904 Primary Limit Temperature Control

The Goodman 20162904 is the factory-original primary limit temperature control for the Amana/Goodman AMES800604BXAA gas furnace. Mounted on the heat-exchanger bulkhead, it continuously monitors supply-air temperature and shuts down the burners if the furnace exceeds its safe operating limit — the front-line defense against overheating from restricted airflow, a stuck blower, or a clogged filter. Unlike a manual-reset rollout switch, the primary limit is an automatic-reset control that re-closes once temperatures return to normal.

Specifications

Type: Primary high-limit temperature control (auto reset)
Normally closed, opens on over-temperature
Factory-calibrated trip and reset set points
Direct OEM replacement for part 20162904
Fits AMES800604BXAA and related Goodman/Amana furnaces

OEM vs. Generic

The primary limit is a critical safety device, and its trip point must match the furnace's engineered airflow and temperature-rise range. The genuine OEM 20162904 arrives calibrated to Goodman's exact specification. Generic universal limits with adjustable or approximate set points risk nuisance shutdowns or inadequate protection of the heat exchanger — not worth the small savings on a safety control.

Installation Difficulty

Easy (1 of 5). The control mounts with two screws and connects via two spade terminals — most replacements take 15 to 25 minutes. Cut power at the disconnect before servicing, and address any airflow restriction that may have caused the original limit to open. When in doubt, use a licensed HVAC professional.

Frequently Asked Questions

Does this Limit Control fit my Goodman AMES800604BXAA — 20162904?

Yes. This is the factory-specified OEM limit control for the Goodman AMES800604BXAA — 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 AMES800604BXAA — 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.
