What to do if Winterwarm DXC heat exchange sensor or flue sensor is overheated?
- C
  Christine BaldwinAug 18, 2025
  If the heat exchange sensor or flue sensor is overheating in your Winterwarm Heater, first ensure that connectors J12 and J6 are properly connected and that connection J12[1-4] (optional overheating protection) is closed. Also, check if the system fan is providing sufficient airflow. Finally, verify the gas valve settings, as the heater might be overfired; if so, adjust the burner pressure accordingly.

  Jill MartinAug 20, 2025
  If the heat exchange sensor or flue sensor of your Winterwarm Heater is not detected or shows a short circuit, measure the resistance of each sensor, aiming for approximately K? at 20 °C. If the measured values differ significantly, replace the sensor.

  If your Winterwarm Heater fails to ignite, several factors could be at play. First, ensure there's sufficient gas pressure. If the pressure is adequate, the gas mixture might be too lean; in this case, adjust the gas valve. Also, verify that the gas valve is receiving 230V during ignition. Finally, check if the ignition electrode is sparking; if not, inspect and replace the cable and electrode if damaged. If the electrode sparks, the burner control unit might be faulty and need replacement.

What to do if Winterwarm DXC Heater has too many flame failures while burning?
- M
  Mary ConwayAug 30, 2025
  If your Winterwarm Heater experiences frequent flame failures, start by checking that the gas supply pressure remains constant while the heater is running. Also, verify that the burner pressure for Low fire is properly set and adjust it if necessary. Lastly, inspect the flue system and fresh air supply for any issues causing flue gas recirculation, ensuring only certified, original parts are in use.

What to do if Winterwarm DXC Heater has insufficient air passage through the heat exchanger?
- K
  Katie AndersonSep 2, 2025
  If your Winterwarm Heater suffers from insufficient air passage, verify that the combustion fan is operational. Check the flue system for any blockages or restrictions. Inspect the pressure switch and its connections. Also, examine the heat exchanger for any flue leakage.

What to do if Winterwarm DXC flame lasts only 5 seconds after ignition?
- K
  Kristina HernandezSep 4, 2025
  If the flame in your Winterwarm Heater only lasts for 5 seconds after ignition, examine the ignition/ionisation cable and the electrode, ensuring the cable has a resistance of 1 k?. Also, ensure the air heater is properly earthed. If these steps don't resolve the issue, the circuit board may be defective.

What to do if Winterwarm DXC flame detected after closing the gas valve?
- J
  Johnny Allen Jr.Sep 7, 2025
  If your Winterwarm Heater detects a flame after the gas valve has closed, first check if the gas valve closes too slowly and replace it if necessary. Also, inspect the ionization electrode for moisture; dry, clean, or replace it if it's wet.

What to do if Winterwarm DXC Heater flame detected before opening the gas valve?
- F
  fburnsSep 9, 2025
  If your Winterwarm Heater detects a flame before the gas valve opens, first verify if there is indeed a flame present before ignition and replace the gas valve if so. Also, check the ionization electrode for any moisture; if it's wet, dry, clean, or replace it.
