What to do if my Winterwarm Heater heat exchange sensor or flue sensor not detected?
- AantoniodavisSep 12, 2025
If the heat exchange sensor or flue sensor is not detected or shows a short circuit in your Winterwarm Heater, the heat exchange sensor consists of two internal sensors. The readings of these sensors may differ too much: measure the resistance of each sensor. The KΩ at 20 °C. If the measured values differ too much, replace the sensor.
