Amana 2100 watt microwave was taking longer to heat. I've replaced magnetrons and capacitors. Heating better but still not full power. Could diodes need replaced or transformers?
So you've replaced the magnetrons and the capacitors? What made you decide to do that? What tests did you do to determined that they'd failed?
You said that you think the oven isn't performing as designed. Did you perform Amana's output test using the IEC705 test method to confirm your suspicions?
While diodes and transformers can certainly be a factor, they can be tested to determine whether they're bad. In either case, they usually short out first. The symptoms (lotsa sparking and/or smoking) usually offers a handy hint that they're done.
Nonetheless...have you TESTED your diodes and transformers?
Anyway. If you could provide a model number and some of the results of your tests using a VOM, maybe I or someone else can offer you further guidance.
A 2100 watt unit is a powerful microwave. It would have to have 2 to 3 magnetrons and the same in rotating areal's, capacitors and power transformers. Tell us what model you have so that we can help you solve your problem. Oh, and test your incoming voltage.
