Mountain Breeze ionisers and the rebranded versions of them had one design weakness. The neon power indicator light. It always seemed to be fitted with a series resistor that resulted in a current level that shortened the indicator lamps life dramatically and also cooked the resistor to the point of sudden failure. In the older PCB based ionisers this sometimes resulted in a power track being blown off the back of the board killing the ioniser completely.
In this video I show how to fit a new standard neon indicator with a more appropriate resistor to give longer indicator life.
You can also just chop the indicator off and insulate the wires appropriately if you don't need a power indicator.
Ironically, the neon power indicator actually draws more power than the ioniser itself.
