Truma Ultrastore PCB BGF 70020-00065 | Boiler Control Board

Truma Ultrastore PCB – BGF

The Truma Ultrastore PCB BGF (Part No. 70020-00065) is a genuine electronic printed circuit board (PCB) used in Truma Ultrastore gas water heaters installed in caravans, campervans and motorhomes. The PCB acts as the central control unit of the water heater, monitoring and controlling key functions such as ignition, burner operation and temperature regulation.

If the control board becomes faulty or damaged, the heater may fail to ignite, regulate temperature incorrectly or stop functioning completely. Replacing the PCB restores the electronic control system of the boiler and allows the heater to operate safely and efficiently again.

This PCB is designed specifically for Truma Ultrastore water heater models, including BGF and similar units used in caravan and motorhome hot water systems.
