To avoid risk of electrical shock, personal injury, or death, disconnect electrical power source to unit, unless test
procedures require power to be connected. Discharge capacitor through a resistor before attempting to service.
Ensure all ground wires are connected before certifying unit as repaired and/or operational.

Power applied to oven in OFF condition
UPPER OVEN OPERATION
L1 line voltage is applied to EOC4 power supply board and the EOC4 board where it is
distributed to one side of the elements.
L2 line voltage is supplied to the double line break relay and to one side of convection and
cooling motors.
If you are experiencing oven operation issues the first step is to always check power source
voltage. This can be done by measuring the voltage between EOC4 double line break relay (L2
input) and EOC4 convection connector (L1 input). You should measure 240 VAC between these
connections with oven in the On or OFF condition.
