How to Fix / Troubleshooting

- Inspect and reseat connectors: With power off, gently press all plug-in connectors on the control board, fan, pump, and sensors to ensure good contact.
- Clean flame sensor: Improve flame detection by cleaning the ionization electrode.
- Monitor supply voltage: If lights dim when the furnace starts, have an electrician check the supply.
If lockouts continue, record any displayed codes and contact a Kospel service technician with this information.
