Bought less than 3-years ago and control board is flashing 88. Tried unplugging then plug back in did not reset. Tried pressing the +- buttons at the same time as may be locked but nothing happened.
Sent in email to the [****] and received a response that they need a video showing the display and the order number, which I provided, but no response at all. I have sent multiple follow up email and they are not responding.
My unit is out of warranty and just looking for information if it is a control board or something else. If control board will purchase and replace. However, no response after a couple of weeks. Will not purchase from them again!
