Pull the fridge out from the wall and check to make sure it is plugged in.
Unplug the fridge and plug in a spare appliance to see if the outlet is working. Check the circuit breaker to the house see If the outlet is not working to see if there are any fuses that are flipped.Inspect the electrical cord for the refrigerator for damage, such as from a mouse or pet chewing on it.
Open the fridge to see if the light turns on. The power to the unit is fine if the light turns on, which means something else is the cause of the starting issue.
Turn up the thermostat on the inside of the fridge if it is set to a low setting. Turn it all the way up and listen for the condenser motor to start. Have the unit serviced by a professional if it does not May be internal problem with component
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.
A circuit breaker 'tripping' everytime the AC unit kicks on 'most always' indicates a direct short (somewhere in the condensing unit), although it is possible that the breaker itself is bad - (but not likely).
Usually the cause of this 'short' will be - either the condenser motor in the condensing unit (outside unit) or the compressor - also in the condensing unit.
If you're mechanically inclined - and "very careful" around electricity - there is a fairly simple way to find out which component is causing the short.
Step 1 - Make sure the condensing unit (outside unit) is completely disconnected (electrically) , i.e. pull the fuses/turn off circuit breaker on outside unit and turn off thermostat.
Step 2 - disconnect the condenser motor (this is the outside fan motor). Note: when you disconnect the wires of the condenser motor "be sure" you mark/write their location, and wrap them in electric tape.
Step 3 - start the AC unit. If the breaker trips again you can pretty much rest assured it's the compressor that is shorted.
To prove it (without a doubt) - go to next step.
Step 4 - "be sure circuit breaker and thermostat is turned off" - and - 'reconnect' the condenser motor - and - then disconnect the compressor wires (mark wires and tape them).
Step 5 - Start AC.
If breaker doesn't trip - you know it's the compressor that is shorted.
If breaker 'does' trip again - then it's possible the breaker itself is bad (not likely) or there is a 'short' in the condensing unit's "wiring" somewhere (not likely).
My guess is that either the condenser motor or compressor is shorted.
Check the circuit breaker(s) for the outdoor unit. Then set the thermostat to make the unit come on and see if the contactor pulls in. If it doesn't turn the fan switch from auto to on and see if the indoor fan comes on. If not your transformer could be shot. If the contactor pulled in on the outside unit check the capacitor for the fan and compressor.
The first thing to check is your breaker box. There should be one double breaker for the air handler unit, that's the inside unit, and one double breaker for the compressor, that's the outside unit. Check both breakers. If you're not sure if they've be thrown, click them toward the outside of the breaker box (off position) and then click them toward the inside of the breaker box (on position). If the breakers are on and you still are not getting any A/C take a look at your compressor, (outside unit). If the fan is running at least you're getting power. However, your compressor down inside the unit may not be getting power or it may need to be replaced. The compressor has a start-up cap. If this cap goes bad or the wires from this cap fry or corrode away, this will also keep the compressor from starting but the fan will still run. If the fan is not running it could be caused by a faulty relay inside the compressor cabinet. This relay is supposed to open and close based on a low voltage signal from the thermostat. I believe it's roughly 24 volts. This relay switches on and off the 240 volts for the compressor and the compressor fan. Often this relay goes bad or the wires leading up to it fry. If you?re going to work on the unit yourself make sure all power is shut off. There should be a shutoff switch on the outside wall near the compressor. I?d also shut the breakers off.
This sounds like your condenser contactor, contacts are stuck. They weld together if an ant or other debree get between the contacts. Turn off the electric breaker to the outdoor unit as if the outdoor unit runs without the indoor unit running you may damage your outdoor unit compressor.
I would suggest you call a service company. The part should run retail @ 30 to 40 dollars then the service call charge. This repair should take less than 1/2 hour.
If you mean the breaker trips it probably is drawing locked rotor amps on compressor. Turn thermostat all the way to the left to turn it off. Restore power to unit. If fans inside stay on, that means the power on still on. Then turn thermostat to the rite to turn it back on. If the power fails again after turning thermostat back on the compressor is probably bad. :(
