Overview
This is a genuine OEM ComfortAlert control board (part #1177402) for the Tempstar T2A324GKD200 condensing unit. The ComfortAlert module is a diagnostic and protection board that continuously monitors compressor operation — current, voltage, and run behavior — and protects the compressor against conditions like locked rotor, low voltage, short cycling, and welded contactor. When a fault occurs, it flashes a coded LED so a technician can diagnose the system in minutes instead of hours. A failed board can leave the compressor unprotected, prevent the unit from starting, or produce nuisance lockouts.

Compatibility
This ComfortAlert board is the factory-specified module for the Tempstar T2A324GKD200 air conditioner and is shared across many ICP-family single-stage condensers built for Tempstar, Heil, and Comfortmaker. Verify the part number on your existing board before ordering, as ComfortAlert modules vary by platform.
Installation Guide
- Safety First — Disconnect power at the disconnect and breaker. Verify zero voltage with a multimeter before working in the control box.
- Access — Remove the service panel to expose the low-voltage control compartment.
- Document — Photograph all wiring and the position of every low-voltage lead on the board terminals.
- Remove — Unplug the connectors, release the mounting standoffs or screws, and lift out the old board.
- Install — Mount the new ComfortAlert board, then reconnect each lead exactly per your photo.
- Test — Restore power, call for cooling, and confirm normal operation with a steady status LED and no fault codes.
Signs You Need a Replacement
- Compressor will not start even though the contactor and capacitor test good.
- Status LED is dark, garbled, or stuck on a fault code that does not clear.
- Repeated nuisance lockouts or short cycling with no real system fault.
- Visible burn marks, corrosion, or heat damage on the board.
