Component Checks
1.
Check Fan Motor and Power Source
If the fan does not run when the switch is on either in the
High
or
Low
position, check the
voltage supplied to the motor.
1.
If the motor does not turn when the proper voltage is supplied to it, check
to see that the shaft turns freely. Replace the motor if necessary.
2.
If the correct line voltage is not measured, check back through the wiring to
the power source, including the interlock system.
2.
Check the Electronic Cell
Visual Inspection – Carefully examine the electronic cell and look for the following:
- Bent plates
- Broken ionizing wires
- Dirt Accumulating on the cell plates
- Cracked or broken insulators
3.
Check for Short Circuits
Use an ohmmeter to check resistance through the cell. Resistance should show an open circuit.
4.
Check Transformer and Voltage Doubler (Electronic Units Only)
This check will locate a faulty component or connection in the power supply of your LAF
M
.
CAUTION
!!! EXPOSURE TO LINE VOLTAGE
IN THIS PROCEDURE WARRANTS SPE-CIAL CARE. BE SURE THE POWER IS TURNED OFF BEFORE CONNECTING OR DIS-
CONNECTING ANY COMPONENT.
1.
Inspect power supply (transformer and doubler) for any physical signs of damage.
2.
Turn the power off and connect voltage meter to the primary side of the high voltage
transformer. Energize the system and check
the line voltage.
3.
Turn off the power, disconnect the primary side and reconnect to the secondary side
of the transformer. A poor reading here will
probably indicate a faulty transformer.
Replacement is in order.
4.
Turn off the power again, disconnect the transformer and connect to the output grid
cap connector. Measure voltage (DC) at about
6000V open circuit. A poor
measurement here should be traced back to the doubler in case of bad high voltage wire.
If the reading is
still poor at the doubler, it should be replaced.
