Propane Space Heater Help

[Banshee]

Gents

As I'm sure you're all aware it's horribly cold outside at the moment which is making getting anything at all done on the truck impossible without the use of my Space Heater.

I have a Clarke Devil 3150 connected to a 47kg bottle of Calor Propane.

It recently just stopped working for no apparent reason. When I try to light it, I start the heater as per normal but when I lose my finger from the pilot bypass the heater goes straight out.

So off I went and took it apart to see if there was anything apparent. At the time I didn't know what a Thermocouple was until I started doing a bit of searching around online but it seems like that is to blame for why they fail in this way.

My Thermocouple certainly didn't look fresh and when I took it off to inspect it, the ground wire fell away;





I grabbed this one from Screwfix which looks similar to mine and modded it so the thermostat was in line





Slapped it all back into the space heater and fired it up and it worked!!!!!!!!!.......... for a minute Then it went out again.

It lights straight back up again and then does the same again and goes back out.

Anyone got any ideas?
