I was having problems with my heater. NO, I don’t fix caravan heaters – but to help you here is how I fixed mine. If you are lacking heat, by searching the Web, I found that there are several problems that seem to afflict these heaters 1) Relays not working: My model has settings at 500W, 1KW and 2KW. If the relays are faulty, this can reduce the power of the heater. In my case, I tested the power input to the caravan to confirm that all my relays were working correctly, with the caravan taking the correct amount of current for each heat setting. You can check this yourself if you are “handy”. Buy a cheap “clamp-on” current meter from Ebay (that can measure AC current) and place it around the LIVE wire only on the supply to the Caravan. (I modified an extension lead so that I could hook around the LIVE wire only to make current measurements safely. The currents should be: 0.5A, 4A and 8A respectively.

As my currents were all correct, this suggested that my problems lay with the Thermostats on the heating element. To fix this, firstly you need to buy a “repair kit” from Ebay (or supplier of your choice). In addition to BOTH thermostats (you can’t test them, besides by the time you have managed to get to them you will WANT to replace both so you don’t have to do it all again!). Where was I? Oh yes, in addition to BOTH thermostats, you MUST replace the Gasket Seal on the Gas Flue.

PLEASE NOTE: As you need to disconnect the Gas Supply and the Gas Flue – you will need to find a handy Gas Engineer or “phone a friend”….

There is a good Video on YouTube here:

Very good Guide to replacing Truma Thermostats, but I would have liked more detail….

If you want to see the original link with comments – It is published on YouTube by “Attic Treasures”. That takes you through the job, but I would have been happier with more detail, so after you have watched the video, you can follow my article below on how I did it…
