It will run for approx 30-45 seconds before stopping, the display also goes blank. Does this sound like the common inverter / magnatron problem mentioned on several posts on this forum. Model is about 6 years old so will probably replace it as repair is looking too expensive. Any advice ? Author Posts Viewing 1 post (of 1 total) You must be logged in to reply to this topic.
