Repair Suggestions
Failure
1.
Type 1
Unplug range or disconnect power.
or
2.
Check that the cable between the User Interface and the Induction
Type 2
Power Control (IPC) is not damaged and is firmly plugged in.
3.
Replace all parts and panels before operating.
4.
Plug in range or reconnect power.
5.
Verify if error is still present. If yes, disconnect power.
6.

by completing the following steps.
2.
Unplug range or disconnect power.
3.
Connect voltage measurement equipment.
4.
Plug in range or reconnect power and check for 240 volts at J1 L to N, and then J2
L to N at the EMI filter board, and then J1 L to N at both Induction Power Controls
(IPCs). If voltage is correct, disconnect power, replace the Induction Power System
(IPS), and go to Step 5. If voltage is not correct, disconnect power and check for
an open fuse on the EMI filter board. If there is not an open fuse, have a qualified

Check the AC voltage with a multimeter.
3.
Is the voltage above 196 volts? If the AC voltage is below 196 volts,
then this failure is caused by abnormal supply voltage.
4.
If the voltage is above 196 volts, then replace the Induction Power System (IPS).
