Same issue I've been saying for a few years now with the Absolute 63. Harman and my dealer refuse to deal with it.
It is definitely frustrating. I went to the dealer yesterday and they are coming tomorrow. BUT now the stove is working right again. I am sure it wont be long until it acts up again but I am going to cancel my appointment to save money on them coming and having nothing to fix at this time. Good luck with yours and thank you for replying!
