PART IV
TROUBLESHOOTING - THE BUTTONS DO NOT WORK
E-48
Repair tips:
1. Sparking from the cell
2. Power contact board sparking
1. Check the electronic cell and unit power contact board
Inspect the cell for bent collector plates, broken ionizer wires, dirt on insulators or damaged or dirty contact plates.
If the cell is not placed correctly, a sparking occurs between the cell and the unit power contact plates. Take out the cell and
put it back correctly.
2. Check the power contact board
Some times, sparking may occur between the unit power contact board screw and the unit high voltage contact plate
especially in moist atmosphere. To fix this problem, you can paste plastic tape beneath the high voltage contact plate or
bond it with hot melt adhesive with hot glue gun.

THE BUTTONS DO NOT WORK
When the unit is plugged in the melody comes on but the buttons do not work, or the unit turns on but the buttons
freeze and a click sound is heard. It sounds like sparking.
Most of time, this problem occurs because of sparking. Any sparking can interfere with the display circuit board wire to cause
incorrect display lights or freeze the buttons.
