Junkers Heater Electronic Module PLUS ADAPTER WIRING
Electronic junction box for Junkers heaters.
It's worth checking the "COMPATIBLE MODELS" tab to see if it's compatible with your water heater.
Junkers Heater Electronic Module is faulty, the most common problems are: it doesn't spark; it doesn't ignite; it shuts off; or even some errors that are displayed on the screen.
If the Junkers heater is not sparking, we should check the spark plugs first; if, on the other hand, it is not igniting, we should check the green burner valve.
If your Junkers water heater keeps shutting off, it could be due to the module, but we recommend checking the glow plugs with a flame detector first. If you have any questions, please don't hesitate to contact us.
