If all the lights on the User Interface are Off and there is no response from
the cooktop, complete the following steps:
1.
Unplug range or disconnect power.
2.
Check the continuity of the fuses on the EMI board. If one or more of
the fuses is blown, replace with a new fuse.
3.
Replace all parts and panels before operating.
4.
Plug in range or reconnect power.
5.
Check that it is working. If it is not, go to Step 6.
6.
Unplug range or disconnect power.
7.
Change the Induction Power System (IPS).
8.
Replace all parts and panels before operating.
9.
Plug in range or reconnect power.
10.
Check that it is working. If it is not, go to Step 11.
11.
Unplug range or disconnect power.
12.
Change the User Interface.
13.
Replace all parts and panels before operating.
14.
Plug in range or reconnect power.
If all lights on the User Interface are Off and the User Interface is making a
beeping noise, this indicates there is a stuck key on the User Interface.
Complete the following steps:
1.
Unplug range or disconnect power.
2.
Open the cooktop and inspect User Interface for any damage.
3.
Replace all parts and panels before operating.
4.
Plug in range or reconnect power.
5.
If the issue is still there, disconnect power and continue to Step 6.
6.
Replace User Interface.
7.
Replace all parts and panels before operating.
8.
Plug in range or reconnect power.

There are 3 types of failures associated with the cooktop. The description of these failures and the impact they will have on the rest of the cooktop are listed in the
following.
Failure – Type 1
Failure type 1 comes from the Induction Power Control (IPC). This failure will affect only one burner. The user may continue to use the other burners.
Failure – Type 2
Failure type 2 usually comes from the Induction Power Control (IPC) (there could be some exceptions). These failures affect all burners associated with that
Induction Power Control (IPC); the user may continue to use the burners that belong to the other Induction Power Control (IPC).
Failure – Type 3
Failure type 3 comes from the User Interface. This failure disables the entire cooktop. When this type of failure occurs, all the burners are switched Off by the User
Interface.

Coil under current
Type 1
1.
Unplug range or disconnect power.
2.
Check for the correct connections at T2A - T2B or T3A - T3B on the Induction Power
Control (IPC) (whichever connection the burner is plugged into). If connections are correct,
go to Step 3.
3.
Replace the burner coil.
4.
Replace all parts and panels before operating.
5.
Plug in range or reconnect power.
6.
Check for proper operation.
7.
If everything operates, end service. If error code still appears, disconnect power and go to
Step 8.
8.
Replace the Induction Power System (IPS).
9.
Replace all parts and panels before operating.
10.
Plug in range or reconnect power.
F-21
Supply power frequency
Type 2
1.
Unplug range or disconnect power.
2.
Replace the Induction Power System (IPS).
3.
Replace all parts and panels before operating.
4.
Plug in range or reconnect power.
5.
If the issue is not fixed, contact a qualified electrician to verify the frequency of the home
power supply is 60 Hz.
