5,200 BTU unit. Compressor and fan both work when first turned on, then compressor quits after 5-10 minutes of operation. Won't turn on again even after 5-minute fan-on cool down. Process repeats after AC unit has been turned off for 10 minutes and re-started. Is this worth trying to fix, or should I replace the whole unit?


This could be just a simple fix of cleaning the condenser coils. If semi-clogged, it can cause higher than normal pressures and cause the compressor to cut out on it protector. Check it out. ... Air Conditioners

I have a air compressor that I know the fan is bad in the outside unit. The compressor is not turning on. Yesterday the only way that the fan would run is with a push, now today it won't run at all. If the fan is not at full strength, will the compressor turn on. I want to know if I need a new air conditoner or is there hope in fixing this unit...


There is definitely hope in fixing this one as long as its just the fan not working. Carrier can easily fix it for you if you want. If you are looking for any more specific information, I would be glad to help but I will need the model number of the ... Carrier Air Conditioners

I have a whirlpool model ACM102xLO that seems to be dying. I cleaned the coils, and the unit seems to operate normally for a few minutes. Fan motor works, compressor motor seems to work. When I checked the amp pull on the fan motor, it falls in the normal range of 1.2A. When the compressor kicks on, the amp pull jumps to around 10 and climbs to a high of 15 or so, then the compressor shuts off and the amps jump to about 25 or 26, before cutting off completely. The amps then drop to the fan motor

Hi, I have a 1.5 ton Coleman Central AC for almost 9 years now. The AC stopped cooling one day. The fan is still working, and I can still hear the compressor "compressing" but no cool air. Does that mean that it is not a compressor failure? A technician tried to put refrigerant into it, but it won't absorb. He still wasn't able to fix it. I just wanted to know if I should spend more money to get more technicians to try to fix this, or if this is a classic compressor failure problem, then


Hello,the problem of the AC system is a little thing that can be fix up in a little time the fan is OK and the compressor is also in good condition base on experience and also collection of date from your statement however, w ... Air Conditioners

We have a 1.5 Panasonic split type inverter airconditioner. Our understanding is that the compressor fan is not supposed to stop at any time. Rather, it just operates at low speed when temperature has stabilized. Our compressor fan, however, stops totally once in awhile and then turns on again. Is this a problem?


The 'usual' operation - is for the compressor 'and' the fan to go "off" once the desired temperature is reached - and back "on" when the cooling area warms back up. This operation is controlled by a thermostat inside the AC. \015\012\015 ... Panasonic Room Air Conditioner CWXC104HU

Compressor comes on, works for two minutes then the compressor shuts off whilke the fan continues. I recycle power on the unit and it continues top operate in this manner. I have left it off for a few days to make saure it was not a iced up unit or overheating but it still operates the same.


Your compressor has a safety built into it called a thermal protector. If you were to feel the compressor after one of these short cycles it would be extremely hot. Your compressor is malfunctioning, and it could be several things. I will list them i ... Amcor Portable Air Conditioner NANOMAXA12000E

I have new Samsung 1.5 Ton Window AC ( around one month old). Whenever AC is switched on in FAN or Cool mode the AC (probably FAn motor) make irritating Humming Noise. The noise slightly reduces after awhile. The noise level reduces when lower Fan speed is selected. This problem was not present in first few days of operation. Whether Compressor is on or off does not make any change in noise level. Noise level is same when AC is run in fan mode as well. We have contacted the manufacturer


It is possible that your AC is not getting the right voltage or frequency and hence is trying to scavenge in gettting the current. It will be good if you can check on the mains voltage or on the wiring for a good 15 amp supply line. If there is any r ... Maytag M6Q10F2A Air Conditioner

After a cooling cycle, when the thermostat call for more cooling, it take up to 5 minutes after the air handler starts for the compressor motor to restart. The top fan operates on the outside unit, but since the house is not circulating cold air, only the room tep air the house heats up about 3 degrees before the compressor comes back on and cool air begins to come from the ducts. Yes. I know there is a safety feature to protect the compressor, but can the cycle be shortened?


No, this cycle cannot be shortened due to the simple fact that this feature is in place to protect your system. Even if it could be, I wouldn't recommend it.Mat ... Coleman Air Conditioners

Air conditioner runs for a few hours and it works - it cools the house. Then it stops cooling - the fan still runs but it doesn't blow out cool air any more. It seems like it's overheating or something. It will blow out cool air if it has not been turned on in a while but once it's on too long it stops. I was told it could be the fan motor and the a/c guy changed the fan motor today but that didn't fix the problem. Now he says it might be the compressor or that I need a new system. I'm jus

Nordyne AC Hello, Our Nordyne DT5QD-042K quit cooling the air. It sounded like the compressor was starting and heat was building up however the fan on top was not turning. It did spin freely and showed no sign of bogging down. Power was present at both leads from the capacitor. Ohmed lead to lead and had resistance, nothing going to grnd from either lead. Last September I had to install a booster capacitor and all worked OK (the fan was operating at that time). I am suspecting the fan mot

I recently had a new outdoor unit installed on my central heat and air conditioning sytem. I have had the installer out 3 times and the system still does not operate correctly. Sometimes when it cycles (every other time or every third time) the unit does not blow cold air. Sometimes the unit comes on not blowing cold air and the compressor fan is running but not the compressor. Sometimes after 15 minutes of this the compressor will come on. What is the problem.


It sounds like the compressor needs starting components installed on it. All a/c units have a run capacitor for the compressor and another one for the condenser fan motor. These motors use these capacitors all the time when the motor is running. H ... Air Conditioners

Have a duo therm penguin heat pump a/c when turning it on the compressor humms but no fan. the fan gets pretty hot upon the roof after 20 sec of operation. the main hot wire to the unit is pulling 18.5 amps when unit is turned on. fan spins freely! ??????


Check the cap for the fan. Will the fan start if you spin it when you hear the humming. Check the lock rotor amperage for the compressor to see if it is hung up. The cap if it is shared could knock out both the fan and comp so check both. ... Air Conditioners

Probablly the fan. Do this test. Move the fan side to side. and up and down. Any more than 1000ths inch play and that motor is bad. When the bearing gets thin the rotor will rub the stator and lock up. This is called polling out. If the motor is stif ... Air Conditioners
