VCC Control Voltage Check
1. Remove the terminal block cover; see Section 030-4.36.
2. With the appliance connected to power and switched on, check the voltage
at the terminal block. There should be approximately 120VAC going to the
VCC control. If there is no voltage, check the wall outlet and breaker.
3. If there is voltage, remove the VCC cover on the right side of the VCC control.
4. Test for voltage (120VAC) at the VCC control (blue/brown wires, Figure
030-68, Item 1). If there is AC voltage, proceed to Section 030-4.39, and
then Section 030-4.40. If there is no AC voltage, then replace the wiring
harness between the terminal block and VCC control.
