Possible Causes
How to Fix / Troubleshooting
Safety first: Disconnect power before touching refrigeration components. Do not attempt refrigerant work without proper certification.
Steps:
- Listen for compressor: Restore power and observe. If the compressor does not start but hums and trips, it may be locked or the start components may be faulty.
- Check condenser fan: Ensure the fan runs when the compressor is on. A non‑running fan can cause high pressure shutdown.
- Feel lines (carefully): The discharge line should become hot and the suction line cool during operation. If both remain near room temperature, the compressor may not be pumping or refrigerant may be lost.
When to call a technician: Any diagnosis beyond basic observation requires gauges and refrigeration expertise. A Manitowoc‑qualified technician should test the compressor, hot gas valve, and refrigerant charge.
