Please Note: This is for the repair of your own controller panel which you need to send to me. I do not supply a new controller assembly to you


Repair of CP25 (CP25-UK) Truma Combi Controller Panel with 12 month warranty


Repair to CP25 panel showing " Connection Error " problem - This is a common problem which I can repair for you. These items were fitted to some Swift and Coachman caravans, replacement control panels are obsolete. The fault is either down to a faulty panel itself or possibly a fault with the main PCB on the combi boiler (see 2nd photo on the listing). If you send in both boards, I can test them both and repair whichever one is at fault. Alternatively send in the CP25 panel and if it tests out OK then you can send in the main boiler PCB at a later date.


Simply checkout on the listing and send your control unit to me, to the address below, please include your name and a contact number.

Ensure your controller is protected from normal postage handling. Enclose a name and contact telephone number with your item.

If you wish to discuss the fault prior to sending it then call me on the contact number shown later in the listing. (You may need to google our company name to get the phone number)

International customers should mark the items as "For Repair and Return" on the customs declaration, I will not be responsible for any import charges incorrectly applied.

The p&p charge covers the postal return of your board. I use Royal Mail First Tracked 24 as a standard return postal service. This has a limited compensation. If you require a more comprehensive return postal service to include a recorded service and insurance cover to a maximum of £750 then please select the special delivery option given. If your item fails to be returned,  I will provide proof of postage to you if required, but the process of compensation claim with the carrier and subsequent proof of value is the responsibility of the customer. My repair charges will still stand in these cases. If required, Non UK customers should contact me before hitting "buy it now" to discuss premium international delivery options.
