Here at Apuljack Engineering we have repaired countless Truma Ultraheat boards with a variety of faults. Many of the common faults are caused by either a burnt out relay or damaged transformer. This kit will allow you to repair your own PCB instead of having to purchase an entire new PCB.


This listing is for a complete kit to upgrade and repair a Truma Ultraheatcircuit board. It contains not only three upgraded relays but, unlike many kits, it also contains the other common part which fails on these units - the transformer.


Also included is desolder wick essential to the removal process to help somebody with just a soldering iron remove and replace these parts. Many forums explain how these boards fail - sometimes this failure is due to the relays, but often it is actually the transformer component. Unlike other kits this is a complete service kit that should restore your damaged unit to a full and upgraded state.


Desoldering and soldering is essential to fitting this kit, a soldering iron and basic soldering skills are required, however we provide full instructions with the kit and a video guide below.

Alternatively, we offer a repair service for the Ultraheat units, please contact us for more information.
