Hi All, Has anyone any ideas, you may remember about October or November I was having trouble with my Carver Fanmaster 2000 heater. Most people said it was probably the slide switches on the heater control so I sent for one of the replacement ones with the rotary knobs instead of slides, I fitted them, and all seamed well apart from the neon lights seamed to flash a little when turned the knobs with the heater in use. I ran the heater long enough to feel the heat from the heater and the fan, that was it job well done. It has not been used over the winter, however today I wanted to clean the interior of the caravan ready for the forth coming season, so I turned on the heater to take the chill of the air, it worked fine at first then I turn the heating down noticed the flashing neon’s on the control again but it seemed to work fine but then I felt it cooling down more than a little. I looked and noticed the neon on the caravan main switch for the heater was out. Checking on the caravan trips they were fine however on entering the house I noticed the trip for the house socket had tripped. Going back into the caravan I turned the heater off by its own controls went back in to reset the house trip however it would not allow me to do so it tripped immediately. I took the fuse out of the heater Isolator in the caravan and the electricity stayed on I removed the mains plug that feeds the heater in the caravan and the electricity stays on The 12 volts works the fan at all times and the neon’s on the control don’t flash while just using 12 volts however as soon as I connect the mains to power to the electric side of the heater off goes the house trip has anyone ant ideas.
probably heating element in heater has blown, causing neutral to earth fault, this would trip the power in the house whilst the neutral is still connected.
turning the heater controls off, only isolates the "live" side. unplugging the heater plug removes the neutral side.
I suspect the heating element needs replacing

Before you think about any repairs, hopefully gas fire works? if so run it high on gas for 24hrs with fan running fair slow. With any luck this will dry out the element/s and cure the problem
