Thanks for using this service. Please be logged in to rate my assistance when we are done. Rating 3-5 is good, but 1-2 is bad so talk with me first.That code is a faulty temperature sensor code. Get an ohm meter and unplug the temperature sensor. It should read 500-600ohms at room temp. If it is out of range replace it.
OK but where do I find the temperature sensor? At the back of the unit or elsewhere? I have an electronics engineer with whom I work and who can help me but I know he will ask for a circuit diagram? Any idea how I can get my hands on one?
