Possible Causes

Normal anti-short-cycle timer in control board, overheated compressor, faulty overload protector, control board timing fault

How to Fix / Troubleshooting

Note: Many Keystone dehumidifiers include a built-in delay (typically 3 minutes) before the compressor can restart to protect it from damage.

  • Wait for restart: After the compressor stops, wait at least 3–5 minutes before expecting it to start again.
  • Check ventilation: Ensure the unit has adequate airflow around it to prevent overheating.
  • Monitor behavior: If the unit restarts normally after a short delay, this is normal operation. If it remains off for a long time or never restarts, see the "Compressor Not Starting" scenario.
