Hi Guys
Just a follow up on this...About three weeks ago i was at my sisters house and her range hood was taken out..I enquired what was wrong with it and apparently it was completely dead...So i removed the pcb and said i would have a look at it....I looked over the track side for dry joints, broken tracks , all looked good , so checked the component side for heated or damaged components , all good.... Got my meter out and checked the primary of the transformer and it was open circuited....Did a google for the part number of the transformer which led me to this thread...I thought bingo must be the thermal switch...Pulled the transformer out and got to the thermal switch and it tested ok...so the primary had gone open.... The transformer had only one secondary winding so i looked for a 12v pcb mount one and sourced it from RS Components part number 732-0389...was a drop in replacement...Installed the pcb on friday and did a quick test and appears all ok ....Have attached a pic with the new transformer installed..
Cost of transformer $12.40...

Hi Shed, Guys,
You could salvage a suitable transformer from a 12 volt wall wart ! That will most probably have the thermal fuse built in.
Shed: My apologies ! I had forgotten about this post and recall saying that I had some thermal fuses kicking about. If you still want one PM me.
It will be after Christmas before I can get around to sorting it.Best Regards:
Baron J.
