You may have a lid switch that has gone out.
What is the model number of your unit, please?
Im sorry but I do not have a service manual for your unit. I will opt out of your question and this will open your question up to other experts to reply.
Sorry for the inconvienience.
Sorry we could not help you, Dave. Your unit is just too new still. That means that the service manuals are not readily available to the general public (or resourcefull experts) yet. The only ones that have them are the authorized agents. And they guard the darn things like they are gold coated with platinum encrusted lettering. Without one there is almost no way that you can diagnose the new computer controlled units.
Best regards; THS
