Overview
This is the genuine OEM Tempstar Comfort Alert control board (part number 1177402) for the T2A360GKD300 air conditioner. The Comfort Alert module is a diagnostic and protection board that continuously monitors the compressor's electrical signature — voltage, current draw, and run behavior — to detect faults such as locked rotor, open circuit, missing run capacitor, low line voltage, and short cycling. It communicates problems through a flashing LED status code, giving technicians a fast diagnosis instead of guesswork. When this board fails, you can lose compressor protection, see false fault codes, or have a condensing unit that refuses to run because the module is no longer passing the start signal through.

Compatibility
Built for the Tempstar T2A360GKD300 condensing unit and the shared ICP / Heil / Comfortmaker platforms that specify part 1177402. Confirm the printed part number on your existing module before ordering, as diagnostic boards across the ICP family share a housing but differ in wiring and fault logic.
Installation Guide
- Safety First — Disconnect power at the outdoor disconnect and breaker, then verify zero voltage with a multimeter.
- Access — Remove the control-box access panel on the condensing unit.
- Document — Photograph every wire and terminal on the existing module before disconnecting.
- Remove — Disconnect the sense and control leads, then unclip the old board from its mounting standoffs.
- Install — Mount the new board and reconnect each lead to the matching terminal exactly as photographed.
- Test — Restore power, call for cooling, and confirm the unit starts and the status LED shows a normal (no-fault) code.
Signs You Need a Replacement
- Compressor won't start even with a known-good contactor and capacitor
- Status LED is dark, stuck on, or flashing nonsensical codes
- Repeated false fault trips or loss of short-cycle protection
- Visible burn marks, corrosion, or heat damage on the board
