Overview

This is the genuine OEM Comfort Alert control board (part number 1177402) for the Tempstar T2A360GKD100 condensing unit. The Comfort Alert module continuously monitors compressor electrical operation and flags faults — locked rotor, open circuit, low line voltage, short cycling, and missing run capacitor — via its diagnostic LED. A failed board can leave the unit unresponsive to the thermostat, short cycling, or repeatedly tripping on compressor faults. The factory board restores accurate diagnostics and protected operation.

Frequently Asked Questions

Does this Control Board fit my Tempstar T2A360GKD100 — OEM 1177402 | Ships Today?

Yes. This is the factory-specified OEM control board for the Tempstar T2A360GKD100 — OEM 1177402 | Ships Today. 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 control board on my Tempstar T2A360GKD100 — OEM 1177402 | Ships Today?

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 control board compatible with Bryant or Payne too?

Many Tempstar 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 Tempstar control board?

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.
