PROBABLE CAUSE
Turn system fan on.
Check wiring or if plug is inserted and receptacle is powered.
Check power switch for continuity with ohmmeter. Replace if defective.
Remove door and press safety interlock with a screwdriver. If lights
come on, bend interlock lever towards front and close door.
1. Remove wire or wire fragments. Replace.
2. Shake large particles out or wash cell.
3. Allow cells to dry completely.
4. Clean or replace end plate insulator.
5. Straighten plates with pliers.
Determine whether high voltage is present by testing power board. If
voltage is present, replace indicator light.
Adjust high voltage potentiometer on power board counter-clockwise. If
high voltage is not present, replace power board.
Remove power box lid and blow lightly for 10 seconds on APS sensor
at bottom of power box. If light does not come on, replace APS.
Check that sensor is located in the plastic bushing at the front of the
power box.
Check that the return duct is installed flush to the top and front edge of
the Air Cleaner duct opening.
Ensure there is a minimum of 360 CFM of air to the air cleaner.
Verify output of transformer. Replace if necessary.
Verify output of switch. Replace if necessary.
Replace power switch.
Test contacts and repair.
With needle-nose pliers, gently pull contacts down or replace contacts.
Allow cells to dry completely.
Wash cell. Shake particle out of cell. Replace wire, if necessary.
Clean ducts.
Remove cells and adjust to original spacing using needle-nose pliers.
Wash cells and clean ionizing wires.
Adjust high voltage potentiometer on power board clockwise.
Realign cell contact.
Repair humidifier. If possible, move humidifier to different location.
If possible, pull down contacts with needle-nose pliers or remove power
box and replace contacts.
Reposition cell handle and place cell in properly.
Use "Fan On" system fan setting for continuous fan operation.
Adjust high voltage potentiometer counter-clockwise on power board.
Straighten with needle-nose pliers.
Replace wires.
Wash cells and clean ionizing wires.
Check operation and wiring of air switch and air cleaner.
Adjust high voltage potentiometer clockwise on power board.
Use correct size of Air Cleaner.
Repair or install central humidifier.
Keep fan running continuously. Ensure that return air grilles are not
obstructed.
Seal or use duct tape around Air Cleaner cabinet.
