Please I tried the same method in testing my magnetron but the fuse wire I tied across the transformer terminals didn't blow up , instead the transformer emitted some smoke , please does this mean my magnetron is good and my transformer bad ???

Dear Parasuraman Subramanian,

I tested my transformer by feeding 12V-AV on the primary side and got about 110V-AC on the secondary.

Does it matter if you swap the connections on the 'F' and 'FA'?

How do you tell if the 'F' and 'FA' labels are missing on a new Magnetron, which terminal goes where?

Sincerely.

In reply to beh.

It cost me Rs.1,250 (Around 17 US$). Microwave ovens are not having good market here, as people have turned away to other methods like Induction Cooker etc. Normal cost on oven is around Rs.5000 to 10,000 (US$71 to US$143)
