Question

GE Model JES1334WD. Having problems with entire control panel going blank and locking up. Can get it started again after clearing panel and resetting clock. Tried to heat for 1 or 2 minutes but it runs for 6 or 7 seconds and then stops. The panel goes to all 8888s lit up and locked up. Any ideas ?? Occasional lucky time will run for a minute or so but this is not consistant.
