Problem with this unit

\015 When I turn the unit off, the motor keeps "humming", also when on, the compressor runs continually. The coils are NOT iced up. Thanks for any help you can offer.\015

I have a carrier 38ckc060370 that runs but the air is not cold coming out of the vents. i checked the copper line coming out of outdoor unit and is not cold either. does this mean that i need a recharge, or could there be some other problem? recently, i've had problems getting the unit to turn off, and had to use the breaker because it would not shut down on its own, but other than that, the unit has never had a problem. the unit is about 4 years old.

If the unit is not shutting down, then there is a chance the contactor has gotten stuck. This is not a good thing. If the contactor were to weld itself shut and the outdoor unit were to continue to run without the indoor fan running for an extended ... Carrier 38CKC060 Air Conditioner

Hi, since you claim that the a/c is working but the air coming out is not cool, then you have a very low freon in the compressor and you need to refill the compressor, Or look for an air restriction. Check your filter first of all..Concer ... Air Conditioners

I built a house in Sept. 2007. I purchased 2 rheem air/heat units. I have had a lot of problems with one of the units. Unit Rheem rpne 036jaz. I have had four different repair men out to fix the unit and still have the same problem. I have had the circuit boad replace in the outside unit three times and replaced the thermostat and the contactor on the outside unit. The inside fan will kick on but the outside unit will not. I can reset the unit inside and it will work for a little while but then

Hi there, I have two Fujitsu DC Inverter split units to heat my flat (england). The temperatures have dropped significantly -2 and below. This causes the outlet pipes to freeze up and when the units are on defrost the excess water gushes out of all other joints in the units. This causes two problems - the units are wall mounted one on top of the other, so the top unit freezes the bottom unit. The second problem is the bottom unit 'dumps' in on the floor of the area which when defrosted s

My frigidaire air conditioners spit dirt all over the floor. My window unit and my through the wall unit in a sleeve both do the same thing.

I have a problem with my central heat / air unit. As it is getting cold now, I am using the heat. My problem is that I must turn the thermostat to the on position to get the unit to come on. In the auto mode, nothing happens. I can get very cold but not ever kick on until I move the switch to the on position. In the on position it works fine. Thinking that my problem was with the wall thermostat, I replaced that. I do not remember having this problem with the A/C. What should I look for to fix t

Look on your thermostat one switch (for the fan) will say off/on/auto. The other switch (for operation mode) will say off/ac/heat. The switches should be set at fan auto and mode heat. Some have an auto for the heat/ac if that is the case your thermo ... Air Conditioners

Our unit is now 6 years old. I have had a continuing problem with the fan unit rubbing on the enclosure. The only way I have been able to stop this is by partially unscrewing the top screws on the outside of the unit. The problem seems to be getting worse though, now I was forced to put a spacer between the inside and outside frame to force the inside unit away from the fan enclosure.

Is the fan actually hitting or could it be a vibration from the fan being out of balance ... Haier HWR08XC1 Thru-Wall/Window Air Conditioner

In hottest part of day it starts blowing hot air. We turn it off for 2-3 hours and comes back on anabnd blows cold air again. Technician unable to determine problem. Says we should buy all new unit. Current unit 10 years old. Coolent level ok. Coils clean. This is a 2 ton small unit cools our master suite only. Our other unit is 4 tons and cools rest of house with no problem.

For this case, either the AC needs cleaning or the compressor may be week.  You may want to check on the thermostat, it may send signal to the unit to stop cooling.  If it is a split type AC, you may want to check for leaks in the tubes tha ... Air Conditioners

I have a Coleman roof mounted AC unit on a travel trailer. The unit model is 83338715. The unit just blows cool air not cold air like it should. I was told to replace the "Hard Start Capacitor" and "PTCR Start Device" which I did. This did not remedy the problem. Any thoughts would be appreciated. Could the problem be the "Compressor Run Capacitor"? Reason being that I hear no change in the blower sound when the unit kicks on???

Blowing 'cool air' could mean - room temperature air or it could be 'cool' because the system is low on refrigerant, and just barely doing any 'cooling' at all.\012\012To determine which is which - you need to know "for sure" if the compressor ... Air Conditioners

I have a Sanyo khs1271 that is about three years old. For the last six months it has been making a high pitch chirping sound in both heating and cooling modes. I suspect the problem is the fan on the indoor unit as the chirping only occurs when the fan speed is on high. So far, the only solution to the problem has been to turn it on quiet mode, which reduces the fan speed and thus makes the unit's ability to heat or cool less effective. Does anyone know how to access the fan on the indoor unit

Hi guys, I try to solve this problem i have with my AC unit American Standard YCC048F. Short: The heating and cooling are ok, the only problem is the fan doesn't turn off even if heat or cool turns off. Some times even if i put the thermostat is on off the fan starts running. I try to find a relay for the fan but i don't know what can be the problem. Please help, for now i am switching on/off the unit to have it run. Thank you. Costi

If the unit has printed circuit board the relay maybe in it which has probably welded contacts, must change the pcb then or try tapping it, it might help or even, try off and on power at circuit breaker it migt reset the pcb. ... Air Conditioners

My Sharp CV-P12PX air conditioner seems to have a vibration / noise problem with some insulation and/or the fan. The unit is brand new and is the second one as I had the first replaced for the same problem. Tilting the unit solves the noise problem but of course that is not a final or proper solution. Any ideas?

Hi, we have a problem with our Weatherking heating unit/ air conditioner. We had it installed 07/20/06. It really never has worked properly. For the last 2 summers in run's constantly.
