My Dacor double convection ovens are rarely used. I already had an issue with "L22 OVER TEMP" 3 years ago. It took 2 workmen to fix it and 2+ visits. Now, out of the blue, the lower over hasn't been used in about 6 months and all of a sudden it starts beeping (like a timer beep). Again, the "L22 OVER TEMP" message and the lower over won't turn on. I'm going to find a different authorized Dacor repairman. I paid over $6000 for these two beautiful ovens. Zweny
