When any difficulty arises it is always a good idea to check that the oven has been connected to the type of voltage for
which it was manufactured. The serial plate is located on the inside of the lower front panel. It will list the type of voltage
for which the unit was manufactured. In addition, a wiring diagram is attached to the side of the slide-out control panel, as
well as reproduced in this manual (see page 30).
Troubleshooting Guide
The left column of the following table lists symptoms that indicate a problem, while the center and right columns list the
possible causes and appropriate corrective action. Note that the recommendations of this table assume that the wiring
connections are good. When checking a component, always check the wiring attached to the component as well.
