Overview

This is a genuine OEM ComfortAlert control board (part number 1177402) for the Tempstar T2A336GKD200 condensing unit. The ComfortAlert module is a compressor diagnostic and protection board that continuously monitors compressor and electrical operation — tracking voltage, current draw, and run behavior to detect faults such as locked rotor, open circuit, missing phase, low voltage, short cycling, and welded contactor conditions. When a fault occurs, the board flashes a diagnostic alert code via its onboard LED so a technician can pinpoint the problem quickly instead of guessing. A failed control board can leave the compressor unprotected or prevent the system from running at all, so a known-good OEM replacement keeps the equipment safe and serviceable.

Installation Guide

Safety First — Disconnect power at the outdoor disconnect and main breaker, then verify zero voltage with a multimeter.
Access — Remove the condenser service panel to reach the control compartment.
Document — Photograph every harness and terminal connection on the board before disconnecting.
Remove — Unplug the low-voltage and sensing leads, release the mounting standoffs or screws, and lift out the old board.
Install — Seat the new board on its standoffs and reconnect each harness exactly per your photo.
Test — Restore power, call for cooling, and confirm the LED shows normal status with the compressor running correctly.

Signs You Need a Replacement

No diagnostic LED activity or a board that won't power up.
Compressor will not start or the board reports false/constant fault codes.

Frequently Asked Questions

Does this Control Board fit my Tempstar T2A336GKD200 — ComfortAlert Diagnostic Module | Ships Today?

Yes. This is the factory-specified OEM control board for the Tempstar T2A336GKD200 — ComfortAlert Diagnostic Module | 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 T2A336GKD200 — ComfortAlert Diagnostic Module | 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.
