So the Quasar is repaired thanks to an offer to assist by craftsman. Thanks for the wall furnace man!

I replaced the fan assembly which houses the fan and that got it going again immediately. I also found that the main power for the appliance went straight from the 3 point plug through the overheat cut out switch first which is located at the very top left corner of appliance before the power goes anywhere else. I worked this out as after replacing the fan and having a premature celebration, the burner stopped working.... found it had no power to main gas solenoid. I eventually tracked it back to a faulty wire/connector at the overheat switch.

Other from that it seems to be working well. Learned plenty about how they work/operate/function too.   

oh and out of interest i did call aber nz and spoke to two different people about parts. 1st guy said he would sell to me, so did the second chick but then she emailed me saying she had better not as they are only suppose to sell to plumbing world or micos and the first guy was just a fill in for when phones busy and didnt really know.
