When oven power is turned on, there is high voltage present in the
electrical components compartment.
Be sure oven is disconnected from branch circuit power before
performing any repair work.
1. Turn on oven power and select Steam mode.
2. Verify that relay operation is correct. Refer to the Operation paragraph for
each oven to determine what relays are active for the Steam mode.
3. CC10-E: Using a clamp-on ammeter, measure current in the following wire
pairs:
B5 - B6 (water heater BH1)
B3 - B4 (water heater BH2)
B1 - B2 (water heater BH3)
If zero (0) amps is measured in any of these wire pairs, the associated water
heating element must be replaced. See page 8-49 for the replacement
procedure.
