Finding your spare part — common questions

Where do I find the Dometic product number?

It is on the data plate (the silver or white label) fixed to the appliance — on a fridge, usually inside the door or on the frame. It normally starts 0092 and is nine or more digits long. Type it into the search box above for the exact diagrams for your appliance.

My appliance isn’t Dometic — can I still find a diagram?

Yes. Type the model, for example Thetford N97 or Truma Ultraheat, or choose the brand and appliance type below. We hold exploded diagrams for Thetford, Truma, Alde, Fiamma, Isabella, Smev, Spinflo, Thule and Reich as well as Dometic.

How do I order a part from an exploded diagram?

Open the diagram. Every numbered part on the drawing is listed beside it with its Leisureshopdirect reference and price, and you add it to your basket from that list — there is no need to search for the part again.

What if my product number isn’t recognised?

Check it against the data plate and try again without any leading zeros or a trailing /00. If it still isn’t found, email orders@leisureshopdirect.com with the number and the appliance model and we will find the diagram for you.

How many exploded diagrams do you have?

More than 7,000, covering caravan and motorhome fridges, toilets, heaters, water heaters, cookers and hobs, air conditioning, blinds, rooflights, awnings, bike racks and more.

Dometic Rooflights Parts Diagrams


Dometic rooflights are essential for natural light and ventilation in caravans and motorhomes, with models ranging from basic manual units to sophisticated electric versions. These detailed parts diagrams cover popular models including Heki 2, Heki 3, Heki 4, and Mini Heki series. You'll find exploded views of opening mechanisms, sealing systems, flynet assemblies, and all the components that keep these rooflights watertight and functional.

The diagrams are particularly useful for seal replacement and mechanism maintenance, as rooflights are exposed to harsh weather conditions and require regular attention to prevent leaks. Common replacement parts include rubber seals, winding handles, hinge mechanisms, and various glazing components. However, some rooflights require specific installation techniques and sealants, and incorrect fitting can lead to serious water damage, so professional installation is advisable for complete unit replacement.
