The contactor is equipped with an overload relay and needs to be reset for the contactor to work. Press the reset button on the overload relay to reset it. It is usually orange or white colored button. But the biggest problem is the compressor not working. It may have caused the overload relay to trip. If it's not the case, check start and run capacitors of the compressor. Replace capacitors if necessary with same specifications.

    Pullout the capacitor and check it. Using an ohmmeter, connect the test
    leads to the capacitor terminals. Do the same with the test leads in
    reverse.The pointer must move quickly to the right and smoothly move
    back to the left. Otherwise capacitor is defective. Replace it.

Coleman mach rv ac unit tripping breaker


If it trips the circuit breaker as soon as you turn the FAN on, suspect either a bad fan motor or a failed fan motor start capacitor. If you are able to turn the fan on but the circuit breaker trips as soon as the COMPRESSOR starts, it is possible that the compressor is seized.
If, on the other hand, the unit is tripping a GFCI (Ground Fault Circuit Interrupter) breaker or GFCI utility outlet, it is possible that neutral and hot are reversed at the outlet into which the trailer is plugged (happened to me this year at an RV park).

Outside ac unit breakers keeps breaking


Check all wiring for loose connections, particularly at contactor. Check for short circuit and earth leakage

Model CKL36-IL was installed just before I purchased home in October 2005. How long is warranty? Recently had it repaired (was dirty). Repairman said it looked/sounded like compressor was about to go...


Factory parts warranty is five years all parts one year labor. Capacitor and/or fan motor has gone out and will need replaced. The breaker will throw itself off if the condition gets bad enough. Suggest not using until repaired, turn off breaker.

I have a Rudd model #uand 060daz the problem is it keeps triping and has to be reset to often what causes this any help would be great


Common problems:

1. Outdoor coil is dirty
The condenser coil wraps completely around a Ruud condenser. It is behind the fins you see facing downward on the case. You can see the inside of the coil looking through the fan blade on top of the unit. You can wash this coil out with a hose and sprayer through the outer fins. It just takes a little longer. The other way to wash it out is to take the four screws out holding the fan shroud on top of the unit. Gently lay the fan motor, blade and shroud over the cover that covers the compressor section. Note the wires to the fan are still wired in, so don't try to take the entire shroud off the unit or you will pull the wires loose. Once you can get into the unit with the fan out of the way, wash through the coil from the inside out, forcing the dirt, etc. through the outer fins. Washing the coil out will help the unit run efficiently and cooler.
2. Your breaker could be weak. If you have an amp meter or can borrow one, you should check the total amp draw on the unit. Look on the unit information tag and it will give you "RLA" or running load amps. Your unit should be running around 10% less than RLA. If your amp draw is good, and the breakers keep tripping , you will need to replace your breakers. You can check your amperage at the circuit breakers by clamping the amp meter around one of the wires that goes to either breaker. Hope this helps. Mark

Turn the thermostat as low as it will go and have someone stand out side, they should here the condensor fan and compressor come on at the same time. They are two distinctive sounds so you should
be able to tell if the compressor is running.

If nothing happens and you are skilled with electrical
you can turn power off and remove the electrical
cover to the outside unit. Restore power and carefully
push in the contactor, if the fan and compressor
starts you have a thermostat or low voltage problem.

If just the outdoor fan runs on any attempt, more than likely you need a new capacitor.

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!

No power to portable air condition


If the filters are clogh with dirt , the unit breaker will shut it off ,it's avery common problem , but if after the filters were cleaned it keeps shutting off , could be a bad fan motor or the compressor itself could be grounded.

Have a Ruud AC unit the problem I have after installing a new condenser fan motor when I throw the circuit breaker the unit will not turn on but when I push the contacts on the contactor in manualy the fan...


The contactor engages from low voltage power from the thermostat as does the outside condensing unit. You may have blown the low voltage transformer or have a loose thermostat wire. Check line voltage(220 volts) to the transformer. Check load voltage(24 volts) from the transformer. If no voltage out,replace the transformer. If you have voltage out(24) check the thermostat wires and the thermostat. If you have a digital thermostat there is a 5 minute delay in the thermostat after power is restored before it activates.

Unit comes on, then throws breaker


Fan should start at the same time as the compressor. If the fan is not running the pressure could build in the system and cause the breaker to trip. Your fan motor may need replacement, or lubricated if it is not a permanently lubricated motor bearing type. Oil ports will be located on the fan motor for front and rear bearings . There may be a dirt plug in the oil ports.
