Hi all

I am new to all this so please point me in the right direction.

I have a 2003 Lunar Zenith Five and have very few problems with it.BUT on my last outing the electric heating ( Truma Ultraheat S3002EL / S5002EL ) stopped working.

It still works fine on gas but when switched to electric the green light on the control panel is no longer illuminated the fan still works fine but no heat ?

As anyone any ideas where the fault lies.

Thanks

please contact gary our expert of fires

i cant offer a great deal of help, But can you hear the heater click, just to prove the heater is getting a  feed. it is very doutfull the element as given up, maybe the relays have given up,the contacts burn away, but they click anyway if you do have power to the panel,gary fits different relays in the panel which are better than the ones fitted. The fan will work regardless as it works on 12 volts.

Garys will certainly help you out when he see`s this post.

As michael says he is the man.

I have had the van serviced this afternoon and he did a couple of quick checks FOC and seems to think its the PCB.

It has power getting to it but not coming back out.

He said i am looking around £100 for a new one.

I have checked all the fuses and the trip switches and all ok. The switch still lights up red. I have traced power up to the PCB.

Hi Gary,

tried contacting you by email at arcsystems.biz but had no reply. I am also interested in buying a PCB from you for a truma 3002, I just wanted to know about the price and delivery etc.

cheers
