Having problems with your Air Conditioners ?

A/C quit running

\015 At 3a.m. our A/C unit quit coming on. It is located right outside my bedroom window,so I can hear it. It made a sound like some kind motor trying to turn over, but never kicked on again. We reset the breaker and nothing is happening.\015

Answers :

This question is really to broad to answer. There are several things that could cause it to stop running. I think I would turn everything off, let it cool down for several hours and try it again. When you kick it back on, take note of what is running and what's not running. Inside fan, outside fan, compressor. If the outside unit will not run at all it could be as simple as a grasshopper caught in the contacts. If you hear the compressor running outside but no outside fan, The fan motor probably needs replaced. Please make sure that all power to the unit is TURNED OFF before removing cover plates on outside unit and before trying to remove insects from contact points. Check all wiring inside outside unit while it is open. Also check capacitors for swelling or leaking. If you don't know how to turn all the power off or open the outside unit, you need to call a professional AC technician. Hope this helps.\015\012kstfas

I have a 8 years old window ac. It's working quite ok. I just want to know which mode is safer low cool or high cool when humidity is high but temp. is about 32-34 degree celcius. Technican advised me to run in high cool mode for some time n then switch is off, but i want long hr. running in low cool mode which is quite comfortable. Kindly advise.

Its not a mater of safety. Its only a matter of witch is best for you. If you want to maintain the temp then leave it on low temp. If you want to save money then you can switch it to power saver mode on high to bring the temp down. Hope this helps. G ... Air Conditioners

The unit has been running for a while with this summer's heat, but recently it cycles on, runs on high, then when it cycles off we get quite a bit of water running out of the front onto the floor (as in 1/2-1 cup). Do I need to clean out the drain system? How can I do that?

I have a Duo-Therm, mod# 600315.321 on a motorhome. Fan motor overheats, but only after the compressor kicks on. New motor, swapped out caps w/identical working unit. Ground is good. Unit will run all day OK w/just fan, but when put on "cool", it will run and produce cold air for 15 min, the fan then quits. Compressor will run for 5 - 10 minutes more by itself, then the circuit breaker kicks.

Model TWEO36C140A1 blower will come on if I throw the breaker switch...but thermostat doesn't seem to be in sync. Fan will run in "on" position and once blower is running, in auto. Blower ran for quite awhile, a couple of days, until I touched thermostat as we were roasting. I knew that would be a mistake! This morning, blower won't run when I switch breaker back on even after letting the motor cool for several hours. Is there a relay switch somewhere? I don't see it. Or does thi

I have a Goodman 3.5 ton, CKL42-1 outside unit. It was not cooling properly so I cleaned the fins because the were quite dirty. When I turn the system on it will run fine for about 20 minutes and then the fan will stop running but the consenser continues to run and it makes a horrible loud sound. Any ideas?

How did you clean the fins if you powerwashed the chances are you bent all the fins over so the fan cannot pull in air and is shutting of on overload when it cools down it will come back on then heat up and shutoff again ... Air Conditioners

I have an LG mini split ac / heat pump system ( LAN096 ) that is only 4 months old was working great in all ways until suddenly it quit heating. I am sure it happened quickly because I was nearby when very warm air changed to cool ( unheated ) and hasn't heated since. When I shut it down and restart it the indoor fan runs right away, which is not normal and the outdoor unit will run for a minute or so then shut down and stay off. The indoor fan will continue to spin as though it is set in a 'fan

Duo Therm dripping water in camper when shut off. My Dometic Duo Therm Ducted AC drips quite a bit of water when shut off after running for several hours on hot humid days. The condensate lines are open. The lines drip steadily while the unit runs. When shut off the lines flow a great deal of water, suggesting that the pan is full. At this point I notice water dripping from the duct work. Thank you for your help!

Mitsubishi MSH12TN fan runs quite fast and noisily even when no heat or cooling is being called for or delivered. I've been told this is normal, but that doesn't seem right to me. Is it? MS09TW units in other rooms run very slowly and quietly, almost at a stop, under these conditions.

If you can not control the fan speed with the control,there is fan sensior on the coil to speed up and slow down fan with the temp of the coil. You will have to call a service tech to replace. Get a free quote first Rus ... Mitsubishi MSH12TN Air Conditioner

Sometimes when the humidifier attempts to start it just howls for a minute or two and then quiets down and runs normal -- OR If I hit it with my hand it also quits howling and begins running normally. It doesn't do this every time it starts - only occasionally. I though it might be the motor temporarily getting out of alignment, but then what do I know. I just don't want to buy a new motor for nothing. .

Yes, you got it spot on - the bushings on the motor have worn out and the fan is slightly out of balance. When it rotates at high speed it autocenters, this is why you hear this only during startup.Before replacing the motor take it apart, you ... Air Conditioners

2001 chevy citation, the a/c just quit working. A hissing sound was heard but the system shows it charged. Also now when the a/c is turned on the car engine runs rough and the engine runs hot, yet has plenty of good coolant. Also when the a/c is turned on now there is a loud click instead of a quieter click. Any ideas??

You may have a faulty high/low pressure control switch which is not cutting compressor function due to low pressure of refrigerant in the system. The hissing sound is caused by a lack of refrigerant passing through the expansion valve. The other thou ... Air Conditioners

I have a Kenmore window air conditioner unit. It turns on, the motor runs, but the fan does not turn on, and the front gets cold to the touch. I have taken it out a couple times and cleaned it and that has no affect. It was jolted and then ran for a day and a half, then quit. Is there anything I can do to get it back running?
