    Farfalla Induction Cooker FEC-20SD6 Error E6

    Dear all,

    I have an induction cooker FEC-20SD6, when turned on showing error E6 which is 'internal temperature is too high' according to the user manual. I am trying to fix the problem but in vain. Hope can get some advice on how to fix it

    Thanks in advance

    Dear all,

    Attached are pictures for the induction cooker. I am trying to locate temperature sensor on the PCB, but in vain. I know there is one at the center of the coil. Anyone knows which component on the PCB acts as temperature sensor?

    Thanks in advance

      Probably a shorted thermal sensor. (If it's the usual sensor type used)

        Dear RJARRRPCGP,

        Thanks for reply.
        That's what I suspect, but unable to find the thermal sensor on the PCB. Don't know which one is thermal sensor

            Dear budm,

            Thanks for reply.

            Initially, I suspected a capacitor was the problem, so I unsoldered the capacitor to do a testing on it. But it seems to be ok. Later I soldered it back and it looked like the electrical connection was damaged, so I soldered a wire across the connection

              i have a feeling it on the top panel, can we get a look at the back of that too.

                Dear goontron,

                Attached pls find the top panel pictures.
                I still can't figure out what's wrong with the induction cooker

                  ok, its not on the front panel. there are 3 wires going to the coil, two big ones and a small one with two or three individual conductors?

                    Dear goontron,

                    I got what you mean.
                    Attached are the pictures. The small one with 3 conductors are the temperature sensor for the coil.

                    There are two black wires. I measured the resistance across these wires both ways. The reading is 111.6 Kilo Ohm

                      111k? thats definitely suspicious, seeming how most thermistors are only 10k. i think thats whats bad.

                        dear goontron,

                        Thanks for reply.
                        Yes, it is true that most temperature sensors are in 10K Ohm.
                        see this site for various type of thermistors:
                        http://www.amwei.com/views.asp?hw_id=61

                        How do I verify that it is the temperature sensor giving the problem, before I make a purchase?

                        Thanks

                          looks like the thermistor is OK. they have 110k thermistors, they are just uncommon. if the room was ~27c when measured it is fine. which leads to bad solder or a bad IC.

                            Thanks for reply.
                            Ok, the thermistor is ok
                            Anyway to identify bad solder or ic?

                            Thank

                              Dear all,

                              I have put the main board front and back side by side to make it easier to check the connection. I also tried to start with the IC LM339N to see if what input that has triggered the error E6

                              Is this the right way?
