I have a multimeter thanks.
I think the main control area looks like a black rectangular box about 6 X 8 in in size - yes?
I will have a look inside, but you won't hear from me again for a while - it's at my step-son's house.
Opened the main control unit.No obvious loose connections.Verified that mains voltage is arriving OK.One small, low-value fuse on the board, but it's good.No other obvious breakers/fuses - not much on the board at all, in fact.Tried measuring what looked like some of the output pins, but no voltage detected on any of them.Can send you a picture if that would help.Do we start suspecting the control panel? It's a touch panel - horrible!John.
