What each Toshiba code means — and what to do next. Stuck? AAA Comfort Air fixes Toshiba systems across Central NJ, often same-day.
Toshiba ductless mini-splits are efficient and quiet, but like any system they occasionally act up. When they do, the indoor unit signals the problem so it can be pinpointed quickly — and AAA Comfort Air services Toshiba systems across Central NJ.
Press the CHECK button (with a pen) to enter self-diagnosis and read the 2-digit code; don’t power off first or it clears. On a fault the lamps flash rapidly. The indicator is a 2-digit check code (remote or flashing LEDs).
| Code | What it means | What to do |
|---|---|---|
| Comm error | Indoor–outdoor communication error | Wiring — call us |
| Sensor error | Temperature sensor fault | Call us |
| Fan motor error | Indoor/outdoor fan motor fault | Call us |
| High pressure/temp | Airflow or refrigerant fault | Call us |
⚠️ Codes can vary by model and control-board revision — always confirm against the label inside your unit’s access panel. For any gas, electrical, or refrigerant fault, call a licensed technician.

You can try one power cycle at the breaker to clear a one-time fault. But if the same code returns, it’s a real fault — repeatedly resetting a gas or electrical issue can be unsafe. Call AAA Comfort Air at 609-665-3022.
