Late to party but you've already wasted the cost of thermocouple and chances of magnet failure are slimmer still! Truma don't suffer corrosion issues on thermocouples connection which is only cause of thermocouple issues and magnet is similar so my first check is control rod fully pushing the...

Original temp sensor is inside control switch so temp sensing depends where that's mounted, particularly where the back of the switch is and the heat or indeed cold its exposed to?! So get yourself a 3.5mm mono jack plug + 600mm of lead and a 10k thermistor, (I used jack to jack 1200mm phono...

You should have.connected between one brown wire and earth, both browns are positive forming a loop in and out of the element coil

I'm more inclined toward something in the tyre or poorly sealing rim causing a leak when the wheel and tyre happened to stop in that particular position for a lengthy time? Cause being similar to pushing the valve sideways, had wheel stopped in another position it wouldn't leak. As a matter of...

The other point I should have made is the 175deg is actually a fail safe, so the need to operate means the 125deg didn't and therefore it's that one that's faulty. Overall though neither should be required to operate but using gas and electric together without enough fan speed to disperse the...

175deg stat does reset but its what's known as a 'self hold', when it trips it has an internal element that is connected that keeps it off until 240v is disconnected from heater, the stat itself can then cool down and resets automatically.

Hi John hope your well? As for the website, it's been a sore point of late but you'll find it's now back up and running for the time being at least. Handy for this thread as it happens, there being a link to a printable Cascade2 manual on the front page 👍

Regards filter/filter housing, look up Filtapac ltd, they've been making both for years, eBay's a good start. Trick with these is use a little silicone grease on filters o-ring and threads first a drop of fairy if your pushed, but NEVER Vaseline! As for cascade, this is my overview, how it works...

Your welcome, stay warm 👍

Yes that's Truma's to match their later grey control switch

It would be easier generally checking vans 240v circuit by plugging a lamp into various sockets in the van, then as I said checking the heaters isolation switch As I said though, only if older Clipsol made beige isolation switch, no issues I know of with Truma's later grey ones

Ps, depends on year, but older ultraheat's 240v fused switched spur were beige? If so then fuse holders are suspect, quick test is to connect output wire direct to input and if green light appears change the spur 👍

No green light on the switch generally means the grey transformer on the pcb has popped, shows itself physically by the top, which should be dead flat, having from a slight bulge to a hole, literally popped! Another killer though regards that lead up to the switch, the pins for it on the pcb are...

Used to be the brown wire in 93 John but this is a 2003, valves been tweaked and the micro-switch is earthed directly inside the valve head. Damaged ignition wire would be my favourite and or a poorly positioned electrode or poor flame pattern

Damp had got in one or both ends of poorly sealed element/s at the 'cold' ends where the wiring connections are
