SOLUTION: After installing a new fuse to the control board the unit is working again.
It seems though that the high voltage transformer (part #09-70724-003) that supplies
the ozone plates is not as strong as it once was and in the future I may decide to
replace this part.
REACTION: Some of the very first things I look for when troubleshooting is to begin
with the main power wires that go into the device. These issues involve checking
for power that makes it through the main fuse, switch, and secondary safety switch.
Next is trying the main transformer to see if power is showing up at the primary
wires, if it is then checking the secondary wires to see that proper power is appearing
at those terminals.
With this ozone unit I discovered that power wasn’t even getting to the main transformer.
By backtracking I found that there is a small fuse on the front control board, looking
almost like a resistor (item F21). I then took a jumper wire to bypass the fuse and
the system worked again!
PROBLEM: We own a ozone purifier machine that was bought in 1999. Probably around
2003 the unit stopped producing ozone. The fan still worked but no ozone. It seemed
as if the high voltage transformer had stopped working, but this was just an assumption
and I wasn’t knowledgeable to electronics at that time.
After teaching myself about electronics and digging the unit out of storage I
was made very happy to find the cause of the problem.
