i have an 88 autohomes karisma. everything electical appears to work but i can not get the heating to work. the gas full and the switch in th cupboard is on, the control unit has power. when it is turned on there is an audiable click but heat does not come out. is there a way of testing the unit or knowing that it is alight without stripping all the units out?
any help or advice appreciated.

Have you checked that gas is actually getting to the heater ???? I have inline taps on all my gas lines you could have the same ??? You say it clicks but no heat how long does it go for before it stops ???

it only clicks the once. there is an inline gas tap and i have tried it in both positions.

i would switch gas off at bottle disconect at the heater turn gas back on and see if any comes out!!! Also clean out the inlet and exhaust , might be blocked one other thing does it have a thermo stat fitted if so check its on high i've tried to light mine befor and the thermostat cut it out !!

cheers, i know that gas is coming out of the bottle as the fridge lights!

no not out the bottle i ment disconect it where it goes into the heater!!!!!!!

ahhhh makes more sense! trouble i its hidden away! oh well strip it out time!

does the fan start up

does it switch itself off ....

how long do you leave it running?

So are you getting cold blown air? Then the fans working but not producing warm air before cutting out?
Try turning the thermostat up higher (if its got one). You need to turn it all the way round on warm-ish days such as this week otherwise the it will not fire up.

Fully charged leisure battery?

Tony

as tony says^^^
if the leisure battery is below 10.5 volts the heater will not keep going.
try it with your engine running

if all else fails propex still service them

My new (to me) 89 Holdsworth Visions heater wouldn't work.

My heater tried to auto spark for about 10 seconds but no heat. I found a shut off gas tap was closed behind a kitchen door, plus once I established gas supply at the heater itself it would only fire up and work if the control unit was set to 1/2 flame- no idea why but now it works every time.

I service the one fitted to my 1988 Leisuredrive camper when I got it. I took it out and had the lid off to see everything looked good. Mine was connected to a tap inserted into the bottle to hob/fridge circuit which you could have missed if you didn't know where it was. I did find a black wire burned and open circuit in the loom and replaced it with a more adequate looking wire. I tested it on the bench with the gas connection connected straight to the regulator and the electrics to a spare battery. It can be used as a fan in one position and with heat in the other. When the stat is turned up the fan runs and a clicking noise ocurrs as the sequence begins. You can clearly hear it light up and feel the hot exhaust. Email or phone Propex for a manual and chat them up about it. I found then very helpfull.
