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
The things I would check:\015\012Is the system properly charged with freon? Sytem may be overcharged.\015\012Is the compressor out on internal overload at the point of failure? If the overload isnt tripped and the compressor is having tro ... Air Conditioners
Indoor fan motor continue to run even if the thermostat is in auto position with the cool and heat switch in the off position. The furnance don't have a fan on and off switch in the furnance like most. The only way to turn the fan motor off is to turn off thr high power switch. I change indoor fan relay but the problem still exist.
Try this, disconnect the fanwire (green) on the furnace, if it shuts off then the hot wire from the thermostat is touching the green wire or bad thermostat. Thank-you-very-much! ... Intertherm Air Conditioners
I have a sunbeam 12000 btu window unit air conditioner. I can't seem to change the fan speed when it is in cool mode. When I put it on fan only it blows extremely cold air and i can change the fan speed. When i press the power button it stops blowing but it sounds like the motor is still running and I must unplug it to get it to stop.
Sounds like the switch is wired wrong.\015\012When you put the switch on fan only the compressor should not run at all, therefore their shouldn't be any cold air.\015\012Check the switch to see if it's wired right. ... GE Profile ASM10AA Air Conditioner
My MSS15 aircondition stopped blowing cold air. Cleaned filters, turned machine off from main power, started it manually; still no cold air. Out side motor fan spins but sounds like compressor is not turning on. What can be the problem?
You will need to check the electrical side of the system....There are many thing that could be wrong. Contactor, start capacitors, thermostat, 24 volt side of circuit, compressor, Breaker tripped, bad breaker, Don't have 240 volts to unit, Manual r ... Air Conditioners
Wiring prob? Thermostat: my fan runs like it should on "on" but when turned to auto the motor makes alot of grinding noise,"like it will not jump out of start", untill it reaches a starting point. already cleaned the squirel cage and there is verry little side play within the shaft. this has been going on for about a year; yet never noticed it with the air conditioning. Could there be a copassator, or wiring issue?
Hello it could be a bad start winding in the motor! If it starts by hand (a push) and runs fine that may be the case. Pull the old capacitor and match it up(uf-value printed on the cap)and replace it ,it might slove the problem and is no ... Air Conditioners
Turned on AC was running fine. 30 minutes later began to hear a strange noise. Opened AC/Furnance closet & heard a sound best described as air letting out of a tire. It seemed to be coming from copper pipe. Minute later sound stopped & air was suddenly hot. As if AC was turned on fan not cold. Went outside & neither fan nor motor was running. Turned fan manually. Ran for about a minute then stopped. Outside unit was making what could best be described as a buzzing sound.
Hi!!\015\012\015\012This means that the condenser fan motor (outside unit) failed, this caused to build hi pressure and either activated a safety valve to release the extra pressure or blew a line and R22 Refrigerant escaped from system. ... Goodman CKL42AR42 Air Conditioner
My AC unit is not blowing cold. I have two. One small and one big . I just noticed that My upstairs was not cooling off. So I turned both units on and went out sid to check them. The small one is running fine fan blowing cold freon running through. The big was not running at all. I sprayed them off and while doing that the fan on the big unit began to turn. Now it is running but every now and then it keep making a noise like a motor is trying to turn on. and the freon line is not as cold as the

The fan in my Heil air conditioning unit runs for a while then stops turning. When I turn it off for a while and re-start it it runs. Is there a way to lubricate the fan. The motor is running but the fan stops.
It is stopping because it is over heating. You will need a new one. Most of the electric motors today do not need lubricating. ... Air Conditioners
RV ac fan runs backwards (blows out air on top of RV.) Runs correctly sometimes but after it satisfies and clicks off when it kicks back on, it runs backwards. The only thing that will turn it back around is to turn off unit and wait for around 30 minutes and turn back on. (won't reverse motion very quickly) Spoke to Coleman expert and was told it is the fan capacitor. Need instructions to identify and change the capacitor. Would like to fix myself since this will be the 3rd time to have it i
Hi, this is strange as I have never heard of this either!!! The capacitor is located by the motor and sometimes clamped to the motor. They can be the shape of a very small can, oval 3" tall with 2 leads on top with wires coming off the terminals. It ... Coleman Mach III Air Conditioner

I have a Goodman CPLE42-1 split system. I had a power outage and my first floor unit would not cool anymore. The air handler/blower in the ceiling is working fine, but the fan outside is not turning on. When I went to look for an overload reset on it, I switched off the breaker on my second floor unit by accident, and now it is doing the same thing. Both fans on the outside will not turn on. Both thermostats will turn on the air handlers in the ceiling. Seems like I re-created the same exact pr

Weather King 8PJ10NDR01 When I turn the heater switch to ON position the furnace runs what sounds like an internal fan. Second, the igniter glows and when it reaches it's hottest stage the fan thrusts air through the air ducts / vents and the burners light for about 30 seconds to a minute blowing cool air. After a period of about 30 seconds to a minute the burner turns off. After the igniter and burners repeat this about 2 times the heater shuts down by it's self, even when the temp gauge has no

Outside fan not running, inside unit running fine. Compressor was running this morning, but no longer. Replaced fan motor, turned power back on, now fan or compressor not running. What else can be checked?

The AC unit turns on and I can cycle through the options in order to adjust the fan speed however the fan does not start in any of the three settings. The ac unit produces cold air, however the fan does not run. The unit sounds like it trys to get the fan to start however instead of blwing air it produces a funny smell. Any suggestions?

Have a Payne pg8uaa furnace. Furnace only works when I run a jumper between R and W. Replace wiring to furnace. I suspect that the outside blower motor is the problem. When furnace is running the blower motor has a humming sound but does not blow air. At this point, I would like to know how you would diagnose a Tjernlund HSUL-J blower motor. Should the motor itself be replaced or should the fan prover be replaced?
You would have to test the motor as well as the capacitor on the motor capacitor goes for alot less then the motor though.here is the pdf manual on your blower h ... Air Conditioners
My fan and heater work fine, but today I turned on my air conditioner for the first time this year. It did not feel like it was getting cooler so I went outside and noticed that my outside unit was not working. I went and checked the breaker and noticed it was tripped, so I turned it off and turned it back on (the breaker). Then all orf the power went off to my house. I then reset my whole breaker box and I heard what sounded like my outside unit explode. I ren over to it and it sounded lik

I have an older 96 Sierra Cobra fifth wheel with a Durotherm Ducted A/C. When you turn it on you can hear the compressor humming and the lines get cold and icy, then thaw and get hot, but the condensor fan never comes on then it bogs itself down and cuts off. I just replaced the run and fan capacitor and it does the same. The fan motor spins freely and while it is on I can spin the blade but it never acts like it is going to run.
Replace the fan motor,the unit is working like it should other than the fan, the reason it is shutting off is called Thermal overload protection, This will always happen if the fan does not come on. ... Coleman Mach 15 Air Conditioner
There is power to the fan and you can hear it trying to turn(it does spin so its not the fan)but no air is blowing,could it be the fan motor,is there a way to tell if the motor is any good,or is there something else that I can check.I am currently unemployed so anything I can do to save a service call would really help.

Blower fan in the inside unit tries to turn on but wont. It can be turned manually and air conditioner comes on and runs fine. The " squirrel " cage spins completely freely and is not sticky or jammed. Is the motor bad or is it a run capacitor. Model number of inside unit is a49-15
\011Sound more like the cap, but if the motor is raging hot, it could be the motor, another thing it could is improper voltage although less likely. But Goodmans/ do have this weird fan relay issue were they just bite it some times. I wo ... Goodman Air Conditioners
I have a Dometic Brisk air AC. Was working fine and all of a sudden the unitsounded like it went to half power. It will restart and sounds labored. It did trip the circuit breaker at the power source once. Reset the breaker and it continues to run labored, both on fan only and cool & fan.
There are a couple of scenarios that can cause this.1) Low voltage in the park. If the performance doesn't increase / doesn't sound normal this evening when electric demand drops off, see #2. If it does improve, you might try moving yo ... Dometic Rooftop RV Air Conditioner

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?
