Answer to: My microwave is not heating, but the timer is working.There is high voltage fuse between transformer and magnetron. Fuse can be fitted on transformer in black tube, or next to the transformer in white tube. Fuse required 750mA - 900mA5kV, mA depends on power of microwave oven. First thing to check if microwave oven not warming up food. Failed rectifier will cause to burn main fuse. http://bargains-zone.co.uk/en/small-electrical-spares/120-high-voltage-microwave-oven-fuse-08a-5-kv.html
Answer to: My microwave is not heating, but the timer is working.I understand, no power at all. Check the fuse in plug (in UK we have), check the fuse in the microwave oven, placed above fan. If find blown fuse, check appliance for short circuits. Working with microwave oven is dangerous.
Answer to: My microwave is not heating, but the timer is working.Your microwave oven not working? I am sure tht many answers blame magnetron is faulty. Why, because is expensive and not worthit to fix. I fixed nearly 200 microwave ovens ( customers returns from shops) and only about 4 magnetrons need replacement, usualy in branded models. High voltage transformer is rare to get faulty ( about 2 out 200 ). Will smell burning smoke from apliance, it is from high voltage transformer. First thing, microwave oven is very danger apliance to repair due high voltage. If you do not know how to deal with electric items ask specialist. On my blog will find instructions how to fix microwave oven. The most common fault and very cheap to fix is microwave oven high voltage fuse. This part is attached to tranformer in black or white plastick tube. Need carefully open this tube using flat screw driver. Will see glass fuse, clearly will show you if is ok or need replacement. If you replace this plart, before try apliance if working is got to check high voltage diode and capacitor. If one of...
