6.1 troubleshooting
Check the problem against the symptoms in the following troubleshooting guide. The remedy may be quite
simple. If the cause cannot be quickly located, shut off the input power, open up the unit, and perform a simple
visual inspection of all the components and wiring. Check for secure terminal connections, loose or burned wir-
ing or components, bulged or leaking capacitors, or any other sign of damage or discoloration.
The cause of control malfunctions can be found by referring to the sequence of operations, electrical schematics
and checking the various components. A volt-ohmmeter will be necessary for some of these checks.
