PART IV

TROUBLESHOOTING - NO UV LIGHT

E-51

When you find there is no voltage on the UV lamp power cord, you will go ahead to open the bottom plate and check the main
circuit board.
1. Unplug the power cord from the unit.
2. Put the unit on the table.
3. Remove the bottom plate by unscrewing 4 screws with cross screwdriver.
4. Set the ohmmeter at the Volt ac range of 200V ac. Check the output voltage for UV lamp ballast at the main circuit board, it
should read somewhere close to 120V ac.
A. If the voltage is OK, you will need to change the UV lamp power cord (White colour).
B. If the voltage is incorrect at the main circuit board connection, you will have to replace the main circuit board. Make sure
the UV lamp cord connection is connected tightly before checking the output voltage.

Note: See how to replace the main circuit board.

Replace the UV lamp ballast

Lift the UV lamp holder with flat screwdriver and take it out.

Check the UV lamp output voltage on the main
circuit board connection.

Set the ohmmeter at 200V ac.
