Either the motor is bad or the pressure relief valve is inoperative forcing the compressor motor to try to start with pressure already in the pump

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.

I have the 919.167320 and it keeps tripping the breaker on start up. It must have tripped it 10 times last night. I have it on a 20 Amp breaker. If I cut the switch off and let the tank get down to 40 lbs...


There is a voltage drop, excessive voltage drop in the circuit.
Anything else on that circuit?
Is the circuit wire size #12 awg thru the complete circuit to the outlet?
Any extension cords being used?
Voltage drop is found in high amperage loads. A motor needs about six times the motors rated full load amps value. Drops found in long runs of wire, in loose connections, in smaller Gage wire than needed.
The power outlet in the garage for the compressor may need the next size wire, #10 AWG. Try using a circuit breaker rated for air conditioning use, they have a trip delay.

Do you have anything plugged in? If they keep tripping with nothing plugged in I would call a electrician to troubleshoot or replace the breakers. They may still be under warranty from Siemans.

Fridge keeps tripping the circuit breaker


get an inexpensive clamp amp meter (Harbor Freight has them). Turn off power to the plug. Remove plug from wall but do not disconnet wires. turn fridge OFF. plug the unit in the recept. turn on the power. set the meter for the higest reading (amps) & clamp it around the black wire. turn the fridge ON & observe start up current & the "run" current. If the fridge is within limits on the data plate the problem is in the wiring circuit, maybe a loose connection either @ the plug or the breaker. if there are several plugs in the circuit, the problem could be in one of them. In addition, if there is a gfi plug in this circuit, it could be faulty also.

Fridge keeps tripping the circuit breaker


Your fridge should draw no more than 5amp. Presuming your breaker is at least 15amp there's a problem. Move to a different circuit first. If the condition persists check the start relay on the compressor. I have a suspicion the circuit may have another item you are not aware of.

Fridge/freezer trips my circuit breaker


This sounds like a grounded wire in your defrost system. Start by finding the defrost timer and checking the wires. One may have been pulled loose or pinched while it was being moved.
