unplug the unit prior to servicing may result in electrical shock.
Each unit is shipped with an instruction manual to be used as a reference guide for all service areas. The manual
shows a picture of the drawer, showing the location of electrical components and a description of each. If the unit
does not operate correctly, or malfunctions for any reason, the following checklist should provide a solution.

Check to make sure cord set is rmly plugged into the power receptacle in the back of the cabinet and
into the wall outlet.
2) Check circuit breaker of wall outlet and reset if necessary.

If heater element is loose, or if it has broken loose from mounting tabs, the wires will short out on the
Metal, causing permanent damage. Both the element and main power switch (with wires on switch) must
be replaced.
6)
