Hi, It's drawing too many amps. Could be a shorted wire, bad fan motor, or a bad compressor. It could also be the relay in the outside unit. One side of the relay could not be contacting.
I would pull the disconnect outside and look at the contacts on the relay for burns, bugs, or dirt. You can lightly sand the contact if they look dirty. A meter is handy to check it for conductivity. Then I'd look at my wires for bare wire or burn marks. Unplug the compressor, plug the disconnect back or breaker and see if the fan runs. You can also check the compressor by unplugging the fan and plugging just the compressor in and trying it, but it's likely a waste of time if the fan ran okay by itself.

Take care

    when you say relay for the outside unit, do you mean the disconnect itself or an internal relay?

HELP???


What was the voltage that you measured? Are the units 220 volt or 120 volt. Units that size are usually fed by 220 volts. What is the current rateing of the circuit breakers? Are they a double breaker with a handeling capacity of 20 amps or are they 15 amps.

You didn't mention if they ever worked? Are you feeding 120 volts or 220 volts to the two units?

Good luck,

Marty

I have had my whirlpool dryer about 4yrs + (geq9800pw2) has always worked fine. Last week it started tripping ckt breaker toward the end of drying cycle. As of this morning, it blows ckt breaker...


leave off the oven and a/c breakers and plug dryer and reset the breaker. if not tripping occurs then one at a time trip back the oven first. if no trip then trip off again and trip the a/c. if no trip then trip the oven back. if trip you may have a wire problem. if dryer trip any way then possibly you have a short in dryer. check the heating element wires,power cord at the dryer side(terminal block).

My goldstar window air conditioner was working fine one day and then the next day nothing works even just the fan part.i tried pushing thei guess they are circuit breakers on the plug part that goes into...


Hi, did the surge /protectors/breakers on the cord reset? If they tried to reset then cut off again, you have a short in a component. Check the breaker that supplies the units wall plug to see if it may be tripped. If it is, it will be in the mid position and turn it off hard, and right back on hard. Hopefully it will hold. Do this, if the breaker is tripped, reset it and if it trips again, go to the a/c and unplug it. Now, reset it and it will hold. If you have a part, motor, compressor, or what ever is shorted to ground, when you plug it in and turn it on it should trip the cord and maybe the breaker to. Check these things I have told you and see what happens. If the unit does start up and start to cool, it overloaded for some reason. A part getting ready to go out, drawing to many amps and tripping cord or breaker. You will need to try and service some of it if it is coming on. Go outside and take your garden hose and give the outdoor coil a good washing. It builds up dirt and will cause high head pressures in the unit which in turn will cause it to overload and shut off everything. Clean it well. Inside, make sure the filter is clean behind the cover on the front and the evaporator coil is also clean. Dirt is a killer of these units and should be serviced at least once a year before it gets hot out side. So, do these things, leave the cord unplugged when washing out side, and we can go from there. If it starts to work good after you clean and service it, that was your problem, but keep me posted on this. I need to no the out come. We can take other steps if needed. Please be kind when you rate me for my help, if you feel I was of help. I will be here to help you more if needed.
Sincerely,

Hi, my Frigidaire AC (FAA068P7A) unit was working fine last year. Put it back in the window today and now it won't power on. I checked the power cord, but cord is fine (I actually opened up the machine...


Sounds like a breaker has tripped (caused by the unit) or is it might just be 'off' for some reason. I would check the outlet (where the AC plugs in at).

If the AC is a 110V unit you can check the outlet by plugging in something else, i.e. a hairdryer. If the hairdryer doesn't work either - then you know your breaker is tripped. On the other hand if the hairdryer 'works' then you know the problem is in the unit, where I'm afraid you'd be better off to have a technician to trouble-shoot it, although you could try sending additional information at this point for more help.

Remember if it is a breaker tripped - it was probably tripped by a malfunctioning Air Conditioner so if it 'trips' again in the immediate future you will need someone to check it out.

good luck!

Torpedo pump...I have one when I plug it in...it trips breaker


I had the exact same issue. I left mine out for the winter and when I plug it in, the breaker trips. My warranty was up so my friend took it apart. The seal had broken alowing water to leak into the bottom the pump where the wires connect to top of motor. This is supposed to be water free and is protected by several seals.

I am currenlty trying to put sealant where the cord goes into unit to stop water from going in. I will let you know how that works.

One tip my friend recommeded is to make sure there is no stress on the cord as it appears this seal is weak and and kind of stress will break it. hope this helps -- Rob

Pushmatic breaker keeps tripping everytime I hit


You have it shorted out somewhere along the line. If it is a light switch you are switching, what have you done lately to make this trip? Anything? You might have a bad breaker. You can check it by shutting off the power, pull the wire out of the tripping breaker, put it in another breaker, turn the power back on, switch the breaker on, then hit the switch and see what happens. If it snaps off, it is not the breaker, but the switch, the wires in the box, or the lights, or something along the line, you will have to check each one. New construction has made all lights and all receptacles separate, so if your house is old, you might be looking at receptacles too. Check anything plugged in to an outlet, make sure there is nothing shorting. Hope this helps.

Everytime I plug in the power cord, it trips the breaker.


Refrigerators are not designed to run on a GFCI. Try a heavy duty extension cord to the fridge from a outlet that is not GFCI protected. If it still trips you probably have a short circuit in the compressor.

Pond pump trips circuit breaker


The circuit breaker trips because there is an electrical short in the pump itself or in the wire feeding the pump. A cause of this could be a bare wire, or a crack in a wire. Remove the pump and put it in a five gallon pail of water and test it. If it still trips the breaker you will know the problem is in the pump or the cord to the pump.

Keeps tripping circuit breaker everytime on plug the power cord in


2 common, possible problems. 1 - there is a "short" in the plug - easy fix - replace either the cord or plug - not expensive. 2 - bad control board - not so easy, not so cheap. Is it brand new, used? Also, it could be a bad "internal breaker" - not easy!
