Hi,
My Dimplex EPX Panel Heater comes on when requested but is more like pulsating/cycling as it heats including the heat light.......
I know this is down to the electronic control panel px08014 but can anyone give there ideas to the part on the control that may be causing it.......
I have changed the transistor BTA16-600B but has not made any difference
Would rather change a part than the whole board at £60......
2 photos below,
I can tell you that the output 220v live is the red wire between the 2 blue wires, it appears to be fed from the middle leg of the transistor BTA16-600B and is only live when thermostat is in heat mode, the other 2 outer legs seem to be live permanently, it is the center leg that is cycling on the output many times a second, the other 2 legs are steady 220v.........
Did read that this type of transistor may rely on a snubber capacitor etc to control the input side to the transistor, could there be a fault there?
Many thanks,
