Kenmore central air conditioning unit tripping breaker each time we turn it on.
The breaker tripping when you turn the unit on indicates a 'direct short' and 99 out of a 100 times the short will be either the outside fan motor or the compressor itself. Either way - you will need a qualified serviceperson to diagnose this problem correctly and make the needed repairs.
Best solution is to call AC person.
However, here's a good way you can get it down to either the fan motor or the compressor.
(1) With all power OFF - disconnect the wires to the fan motor
(2) turn on AC unit
(a) if breaker trips it means the compressor is probably the shorted component.
(b) if breaker DOES NOT trip and the compressor runs - it means the fan motor is shorted.
(3) If breaker tripped with the fan motor disconnected meaning the compressor is probably shorted you can then (with ALL POWER OFF) 'disconnect the wires going to the compressor' and re-connect the fan motor wires. Turn on power - and if fan motor runs (with compressor wires off) you know it's the compressor that is shorted.
After all this you will now know which of the two (compressor or fan motor) is shorted.
If it's the fan motor you can with 'limited mechanical experience' change the motor yourself, but if it's the compressor you will need to call a serviceperson because of the expertise needed to replace the compressor.
