Fan Test
Each power board or generator board has a replaceable 12 VDC fan. It is not possible to check the fan by measur-
ing the resistance. Resistance is never constant.
1.
CI152TF/S and TM15TF/S -
Turn the coil assembly on at Boost for each generator board. The fan starts upon
entering Boost.
2. Use a 9 volt battery to energize the fan. Black wire to negative and red wire to positive.
3. Ensure the fan vent is not blocked.
4. There is no minimum distance to non-combustible surfaces below the module. However, a structure too
close to the fan vent, or an appliance that is getting warm can affect the element heat sink temperature on the
CE152TF/S or the coil NTC sensor on the CI152TF/S and TM15TF/S. If possible remove the structure from
beneath the module and test again.
HOT Indicator Stays On - CE152TF/S
HOT indicator LED is time activated on the CE152TF/S.
1. LED is time activated between 7 seconds and 370 seconds depending on what power level is selected.
2. LED turns off after allotted time based upon what power level was selected.
3. LED stays on a maximum of 60 minutes after all element assemblies are off.
4. Cycle unit power.
5. Ensure fan is operating and fan vent is not blocked.
6. If LED does not shut off after 60 minutes, replace the control board.
HOT Indicator Stays On - CI152TF/S and TM15TF/S
Once HOT indicator is on, it stays on until a coil assembly NTC reads below 50° C (122° F).
1. Check coil assembly NTC temperatures in Diagnostics. They should be consistant. A defective NTC reading
higher than the actual temperature would require replacing that generator.
2. A warm coil temperature can be caused by heat on the coil assembly such as from direct sunlight or a hot pan
sitting on the coil assembly.
3. Cycle unit power.
4. Ensure fan is operating and fan vent is not blocked.
5. If no coil assembly NTC is reading 50° C (122° F) or above, replace the control board. A damaged control board
or stuck HOT indicator may cause the issue.
No Pan Detection - CI152TF/S
The pan detection system is an integral part of the generator. Only magnet pans work with induction generators.
1. Test pan for magnetism by sticking a magnet to the bottom and side of the pan.
2. Verify pan is the same size as the coil assembly.
3. Check for error codes in diagnostics.
4. Check voltage to the cooktop. See error code E6 on page 4-9.
