Abner S Cooper City , FL August 13, 2020 F90 code; door lock intermittent burner warning lights flash burners will turn on when locked NOTHING on the web about my Electrolux slide in range with conv oven. I found a similar oven with video. Video was no help. I replaced the lock motor first, then the oven light switch, worked ok for a short while then F90 fault again. Some guy with a similar oven said he replaced the control unit, so that’s what I did too. So far it works fine. Our range was pretty expensive and still looks new at 11 years old. Hope it keeps working. I have used APPliancepartspros for years for all my problems. Very happy with them. Just wish they would have had video’s of my range and how to take it apart.
