Question about Goodman CKL30AR30 Air Conditioner

We had a lightning storm and now the ac wont work

The fan system works but the unit outside does not. I can hear a slight electrical hom so it seams to be that power is getting to the unit outside but it is not running. I have reset the circut breakers. Is there another reset on the unit itself inside the actual box?

    AC turns itself off and back on at will. Only way it works more than 12 hours is to turn the electric power outside off.

That is correct also. Down here in Tornado alley, we have lightning strikes all during the summer months, and from experience ,we mostly have tripped breakers and or exploded or swollen capicators or that little silver can. if it looks swollen at the top then it exploded and needs replacing.Also look in the outside disconnect box for blown fuses, oh yes ,the light humming noise comes from the contactor being pulled in by the inside 24volt system from the furnace. Thank-you very-much

Depending on where you live, there are electrical codes that require a 'disconnect' near the outside unit.. This is to be removed prior to servicing that unit and prevent the service person from getting injured if someone inadvertantly turned it on The humming sound you may be hearing may be the fan motor insise that unit, It is possible that the lightning strike generated a surge that damaged that fan motor winding.. With the protective screen removed and that unit disconnected from power.. try spinning the fan by hand to make sure it is free to turn, then reassemble everything and see if will start up. If it is a 220VAC system then you could also be missing one phase of power..You might want to contract an electrician for that aspect of troubleshooting. Be careful and goodluck..

Problem with GE PTAC-Model# AZ28E09DABM2 - Why won't condenser kick on when switching to AC from Fan. AC was working fine until today...Fan is still working...Pulled the unit out and could feel the h


Hummm. A bit difficult to solve this problem. Seems like the condenser outside is not working, I mean the fan of the condenser. Looks like you have a wall A/C and a wall A/C always have condensers outside the house and near the A/C. Have you checked if the fan is spinning? I don't think the compressor is at fault but check it anyway. You should be able to hear the compressor running either in the wall unit or in the outside condenser housing. The only heat you should feel is from the condenser itself. If you blows warm air, that means the fan is working, if not that means the fan is not working. But don't be confused with the fan not working because in winter time sometimes the fan is not working and some times it does. As I said, it's a difficult problem to solve but at least start with checking the situation with the fan in the condenser.

Power went out for 3 seconds electric storm warnings but did not see/hear any lightning strikes. Central air-conditioning fans spins But the compressor doesn't turn on. There is one condenser and looks...


During these storms power gets shut down fora sec and comes back with a tsunami type surge. why? Because the generators are going full blast at the electrical plant in your area. No load is applied anf they sky rocket into Zapland babes! Any slight glitch or momentary outage causes a surge. It goes away but it comes back with a fury. So if your AC's run cap is a little old and tired from workin that condenser like it ain't not thang, Then the resulting surge will zap that puppy and it will look like this:
themobilian_2930.jpgRemove the power from the outside unit and look at that capacitor. It prob has went under. If it is leaky or preggers, it is bad. Replace it and party on! More here

1 posible cause.the thermostat supplies 24 volts to the outside unit to control the contactor if you hear a ligth huming on the outside unit this is the being activated. if this is the case then
check to see if any ants are in or around the unit see video, they will usually climb to dry areas before during or after a storm and for some reason they like the contactor if this is the case cut all power to the unit and clean contactor spray the area around the unit with an insecticide ( not the contactor) replace cover and test unit.

Had a lightning storm,now brand new aircon wont restart,remote is ok


The electrical storm may have caused a power surge and burned out the circuit board. Especially, if the power went out briefly and then came right back on. Most manufacturers recommend turning the unit OFF during a power outage/electrical storm.

Hope this helps you.

Fan does not spin


Window unit or outside unit? Start and run caps are large problems,especially after several years operation or a lightning storm. Post more info. A humming sound in a fan or compressor that won't start usually means the capacitor got blown out.. It cost less than $30. (plus service call). LOL

Location of overvoltage protection


Go outside to the condensor, its unlikely that the fuses are there unless it is an older unit. Turn off the power and open the power disconnect box. That is one place the fuses or breaker could be.

In the house you should have an electrical panel usually grey in color. Open the service panel as it should be hinged. Most of the time the fuse or breaker is labeled AC Unit andThe rating should be
anywhere between 25amps-60amps.

Ac unit clicks outside but nothing engages fan or compressor on unit furnace still runs for heat setting and fan still blows but ac will not engage just hear a clicking was running for three days this...


Have you check the outside breaker? If its ok then you got a problem in your electrical system inside the unit probably the contactor is not engaging this is where the 24 volts from the thermostat calls for the 240 volts to run the condenser fan and compressor. Be careful checking this out because of the high voltage.

My Duo-therm Brisk-Air by Dometic rv ac wont cool.(The fan runs )


Usually just listening closely will give you a rough idea where to look for problem. When you have the fan on and switch to cool, (with temperature turned down low obviously) do you hear any type of "moaning" sounds from AC unit, or see lights in RV dim slightly indicating that compressor is trying to engage? Is the breaker tripping when compressor tries to engage? Do you hear a "click" from AC unit when switched to cool? If none of that happens, then I'd start thinking thermostat, or compressor relay. Normally if it's a faulty capacitor, the compressor will try to engage but will make a "moaning sound" and usually trip the breaker due to excess current draw. Someone experience in electrical should be able to test relays etc, but whoever does work on it, should be aware that those capacitors, as well as hydro in general are very dangerous to work with. The ("zap",- Shock) that you can experience from a capacitor or hydro, can be fatal.

My outside unit is humming and the fan is not turning.


You may have a bad running capacitor on the outside unit. It is a round or oval can that has three sets of prongs on it. Sometimes they will swell up and go bad after a lightning storm or power surge.
