• If the short is in the collector section, look
for a large piece of foreign material bridging
the collector plates or a defective insulator.
• If the short is indicated to be in both
sections, it will probably be a foreign object
bridging the air gap between the ionizer and
the collector.
c. Open Circuits: Although open circuits can
occur in the secondary, they usually take place
in the primary. If the unit contains only one
power supply and the indicating light does not
glow the outage is probably one of the following:
• Supply line power to the control
disconnected. Reconnect.
• Open access door interlock in control of
electronic air cleaner. Be sure all access
doors are properly closed and secured.
• Blown in-line fuse located on the transformer.
Identify short and replace fuse.
• Outage in the power supply. Look for
charred or burned components or a loose
wiring connection. Replace power supply or
reconnect wiring.
• Defective indicating light. Replace light.
