So mike,I cleaned out the combustion chamber of this paraffin heater in the old shed which isn't too warm.
I'm assuming,condension got on the PCB.
I brought the heater to the house and fired it up.
It ran ok for 20 minutes then just stopped.
No power even at digital display.
There are two 5 amp glass fuses on PCB.
Both in good condition.
Power go's in and out of the first one.
No power reaches the second one.
The box capacitor,three varistors and the DSA 1
are the only things between the two fuses.
Thanks for looking
