4.3.1
Incoming Power
Before troubleshooting any of the electrical parts or
assemblies, verify that power is being supplied to the
cooker. Incoming power is connected at the boiler (or
direct-connected steam) control box located in the base
cabinet. With power connected to the cooker, an AC volt-
meter is used to measure 120 volts across L1 and L2. If
120 volts is present, and the cooker will not operate, the
fault lies within the electrical circuits of the cooker.
