After the oven heats up and about 10 min into the heating or backing cycle, the control panel starts flashing L@ and beeping. It does not stop until you turn the oven off for awhile and then back on and it will do it again after a while. I do not find anything that tells me what L2 means as an error message. Can anyone pls help me of give me a work around that is easier than re-starting the oven? thank Erling@Smedvigs.com
