My amana ac unit over heats the circuit breaker and trips it off after running for about 15 minutes. It will not blow the fuses on the outside disconnect next to the unit outside.
What you described 'shouldn't' be happening - "if" the outside fuses and the inside breaker are sized correctly for your air conditioner.
I would make sure that the fuses in your outside disconnect were the proper size (for your AC), and that the inside breaker was of suffienct size to handle the air conditioner, and whatever else might be on the circuit.
Note: You would never want the 'outside fuse size' to be bigger than the inside breaker.
For example: 50 amp fuses in the outside disconnect and a 40 amp inside breaker is a no-no.
Often, for whatever reasons - someone will put larger fuses in the outside disconnect than what is called for.
When this happens the inside breaker is the only safety on the AC.
The problem is - for whatever reason - your inside breaker should not be tripping off.
It's likely that the AC may be on a inside breaker "that also has other things i.e. dryer, electric range or Refrigerator," and therefore any of these components 'including' the air conditioner could be causing the inside breaker to 'trip.'
One way to check this would be to 'un-plug' whatever else you had on the inside breaker - and then run your air conditioner and see if the breaker trips. Let's say you have the refrigerator and the air conditioner on the same inside breaker. You suspect the refrigerator is causing the inside breaker to trip - so you unplug it - and then turn on the air conditioner. "Now" it does not trip the inside breaker and assuming you have the proper fuses in the outside disconnect - you could safely say the air conditioner is ok - but - the refrigerator might be on the blink.
It's also possible that you just have too much on the inside breaker and you need to plug the refrigerator in to another outlet.
Still, if it was me - I think I would really think 'hard' about calling a Service Tech out - and let him/her diagnose the problem.
Hope this helps.
