    What error code are you receiving? What part number did you replace?

    It's a up side down F backwards 3

    I was told by a service tech this was referred to as the Key code?

    I am looking to repair this is it a possibility that the main board is at fault.

    The LE the l should have a small line through the vertical the manual says to call service tech. I did that they told me it was the thermistor and would cost 200 to repair I decided to order the part and replace it myself cost 19 dollar and 1/2hr my time. But it is still the same.

    Not sure if i trust the technician or it was coincidence. Any help would be grateful.

    I think the error code that you are receiving is a "tE" which indicates a problem with the thermistor. There are a few things that we see cause the tE error. It can be caused by a broken wire at the thermistor, a bad connection at the main control board, bad thermistor, bad control board, or a wiring problem. Let me know what you find.

    Yes I would inspect the wiring, and if that is good then I would replace the control board.
