SOURCE: When I turn on my air the compressor comes on and

most likely your compressor is DOA, call a comapny and have them investigate further

SOURCE: Very hot outside. blower comes on but outside fan

Check the voltage source for the fan and compressor
Check the start capacitor for the compressor.If its over heating :bad compressor

SOURCE: Compressor blow circuit breaker when turned on.

Yep and your compressor has given up the ghost it shouds like.. do not continue to reset it call a tech on this .. you are adding to the contamination of your system and makeing really hard to clean up internally. In the future if you reset the breaker and it trips right away just stop right there and call a tech.

I have a 5 hp compressor. It will turn on and run maybe 5 seconds and then kicks my breaker out.


you could have a weak breaker or the breaker is not rated for the draw of the compressor have a pro check it out

What causes caravan aircon to trip circuit breaker on start up


My first guess would be that the compressor has seized. If not the compressor seizing, then I would look for a short to ground in the wiring. If you pull the cover of the AC you will most likely find that the compressor motor is plugged into a receptacle. If you can unplug or otherwise disconnect the compressor motor from its' power source and activate the thermostat to run and the circuit breaker does not trip, it is the compressor motor. If the circuit breaker trips, then it's in the wiring.

Hello, I have a duo therm ac unit, the fan works fine in all the Fan only speeds, but when the ac is selected, the compressor comes on and the fan drops down to less than half speed. you can hear the fan...


Check incoming voltage circuit and wiring for proper gauge wire etc, and have compressor start capacitor tested, or replaced. I'm curious as to why circuit breaker didn't trip in panel when compressor causing so much current draw, that's reason for checking wiring etc to AC circuit.

Need a circuit diagram for zanussi chest freeze zfc321wb thing has stoped working after only 2 years think the motor thermal switch is open circuit but need diagram to test properly can you help?


There should only be 2 wires for compressor operation, (brown and white or blue and white), it you only have 2 posts with wires to them on your thermostat, take the wires off the posts and join them, if compressor is good, it will start but do this with GREAT CARE, exposed wires are dangerous and be sure to disconect the power from the wall before and after doing the above, good luck.

Everytime my central air unit kicks on my circuit breaker trips. It didn't do this last year or even earlier this year


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.

Hope this helps.

Good Luck!

Why does the electric breaker trip when my compressor wants to draw current?


The breaker is tripping because the circuit is overloaded. In the winter this is a common problem with a cold compressor at startup. If it is doing it in the summer then it may be you have too small wiring or too small a breaker for the circuit. A 20 amp breaker can handle 12 gauge wire up to 20 amp load. If you need more then you must have 10 gauge wire on a 30 amp circuit. A 240 volt compressor requires a 30 amp breaker and 10 gauge wire. What make and model compressor do you own? On the compressor it lists the load and requirements. Tell me the make an model and I can tell you the wiring requirements.

Blows fuse when tring maintain pressure ? Its a craftsmen pro series 150 psi 25gal on 20amp outlet with 10g wire to its own 20amp circuit breaker?


check amp requirement on compressor info plate might need 30 amp outlet also if you have it plugged into long thin extension cord it will not turn fast enough cant get current it needs causing too much draw blowing fuse try plugging directly to outlet

I have a 2hp compressor motor that keeps tripping the breaker after about 5 minutes of use. i have changed the caps but it keeps popping the starter cap. is the motor just bad?


Our 2 HP Speedaire horizontal tank compressor is rated 115 / 230 volts at 24 / 12 amps, respectively. This means at 115 volts, a 30 amp circuit breaker is the bare minimum. That also means that the wiring should be #10 copper wires for short runs, but the next size up; #8 copper wires would be better connected to a 40 amp circuit breaker. Running at 230 drops the amperage requirement by half, to 12. A #14 copper wire is minimum for short runs with a double pole 15 amp circuit breaker, but #12 copper wires connected to a double pole 20 amp circuit breaker would be better choice.

If the compressor is cord connected (or even directly wired) with the minimum sized wires, it will likely a voltage drop problem unless very close to the panel. This problem is more pronounced as the distance between the circuit breaker and motor increases, or when smaller wires are in the circuit. All the voltage at the circuit breaker does not reach the motor, as it is lost as heat; so the compressor only sees 90 to 105 volts instead of the 115 volts it expects.

If the cords, connections, etc are getting hot, it is a tell tale sign of under-sized wires and /or poor connections. Once you solve these problems, the compressor should run "as advertised " because motors usually don't "go bad" but fail all at once. Unless you have a bearing problem - or there is a problem with the load itself (compressor).

I hope this helped.

Frig keeps overloading circuit breaker, just repaced relay


I think the compressor has a problem with its internal running coil , or it's grounded.To check it you can disconect the power to the compressor and then turn on the breaker , and if doesn't tripped the breaker ,you know the compressor is bad.

Knocks out house curcuit breaker and stopes running. Use to work fine and did for at least two years now kicks out breaker after running for a while. Have moved it to different circuits and still does it....


You will need to put an amp meter on the compressor wires and monitor the reading till it trips the breaker. If the reading exceeds the name plate spec then chances are the compressor is going bad.If the spec is in watts, take your amp reading and multiply it by 120 volts this will give you the wattage of the compressor. For a second opinion take it to repairshop to see if it is worth repairing.
Good Luck!
