I have been having 2 issues on my oven. 2 years after purchase it lost power and a tech came out and replaced something for $250.00 and ever since the display is so dim I can hardly read it. I dealt with it over the years. Now, without touching it, at least once a day I walk past and notice it shows F2 on the display. I hit the oven off and it goes away and the clock (dimly) shows back up. When I heat up the oven, sometimes it stays on the entire time and sometimes it shuts off the display and turns off the heating but the fan still runs cooling it off.
Any ideas?
Thanks in advance for any assistance you can provide.
