Customer Question
We had a transformer...

We had a transformer blow and were out of electricity for 3 days. Now the A/C come on for about 3 minutes then the outside unit shuts back off

Contractor's Assistant: Did you double-check the thermostat? And what about the unit's filters?

Check the thermostat? Filters are good

Contractor's Assistant: Do you plan on doing the work yourself?

Depends on the scope of work

That will tell me if the compressor is running not and if not we will then have a look at units 'run capacitor' that may need to be replaced.

click here please, it will have about 5 wires attached to it... if its swollen or oily its bad and is the cause of the problem.
