Air conditioner turns on in the inside but not the outside

Check inside unit see if 3 amp fuse blows then look outside see if thermostat wire going in unit is rubbing and shorting out

change capacitors.

The outside and inside coils may need cleaning. Clogged coils cause excess pressures and heat of the freon that can cause safety switches to shut er down. Eveen a faulty power relay in the outside unit.Otherwise you may need a serviceman to locate the cause.

The compressor is not running or has lost the refrigerant charge.

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.

Could be a wiring problem or a lack of refrigerant. All you can do is professionally have the unit checked and serviced.
Hope this helps I take the time to answer your question so please rate me

If you turn down the thermostat to the air conditioner and the unit outside does not come on, you could have a few different issues. The usual suspect is a start capcitor. When you adjust your thermostat you should hear a click from the outside unit. If you hear a click but nothing happens, check the power disconnect out there by the unit. I recently had to replace mine because it finally just wore out. It can also be the contactor, the fan itself or the actual compressor.

check you filter then you evaporator coil inside your furnance .....if that doesn't work your outside unit's coil needs to be cleaned

ya the compressor might be switch off by the thermostat . the thermostat setting might be not cool or # 2. Or thermostat need replacement if you had set it to the cooler side.
