Hello my air conditioner is not blowing cold air. It seems like only the fan is working. I set the temp to between 16-18 celcius and the temp that is showing is 28 celcius. Also is showing E5 on the ac small screen. It was serviced about 3 weeks ago and was working fine. This problem started about 2 days ago. Nothing has changed and nothing has been tampered with. Hope you can help Thanks :)


What did they do when it was serviced?It sounds like there may be a leak if it does not get cold at all anymore.Although,lasting 3 weeks,depending on how much you used it,it would be a very tiny hole leaking.The other most likely suspect would be the ... Air Conditioners

Problem I turned on my air conditioner this spring. I turned the switch to cool on and the air conditioner fan not going. I took cover off and got new capacitator didn't work. I took fan motor into electric shop and checked out fine. When I turn switch on the contact switch engages and there is a humming noise. But the fan does not work. the compressor doesn't start up. The model is at least 10 years old. How do we tell what the SER rating is?

How do I know if compressor of my house air conditioner is turning on when I start my air conditioner? When I start my air conditioner the fan outside the house turns on, the air is blowing from the vents in the house but the air is not cold at all.


If the compressor is starting there will be a very small dimming in the house lights,if you go outside to the unit and start it from the outside disconnect when the compressor starts you will hear a whine type noise coming from the outside condenser ... 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

Air Conditioner was working fine last summer but outside fna not working. Not hearing any sound at all. I can move the fan amanually and it seems fine. There is an electrical box next to the main electrical box on the back of the house with 2 fuses in it but I can't tell if they're bad. I thecked the thermostat and it apears to be fine. The air conditioner furnce kicks on and blows air out of the registers. It's just the main unit outside that's not working.


There is a relay in the outside unit. Check for 24 volts a/c at the two wires coming from the furnace. also there may be a mouse nest in the control comartment where the relay is and they tend to chew up wiring insulation and sometimes wires get disc ... Carrier 38CKC042 Air Conditioner

My unit is running but not blowing cool air. I went outside and the condenor fan was not moving. Took a stick and shoved a blade and the fan started moving but the air is still not cool inside. I did notice the air coming through the unit outside after fan was blowing was cooler than my 2nd a/c unit that was working fine. I wondered if the entire unit was frozen. I turned off unit at thermostat and figured I would see what happens tomorrow


Sometimes on new units it is common for the fan to not start until you give it a push. Did you happen to hear if the compressor was operating? If the unit was froze-up the Insulated Suction line would also be iced over as well. If it wasn`t it is mor ... Carrier 38CKC024 Air Conditioner

My air conditioner has started leaking and has very poor air flow. It worked fine in winter but when I switched it to cool water is coming out of it. Sometimes the fan will work (no cold air) for about 20 minutes before it starts to leak, other times it leaks straight away. Any help appreciated.


This sounds like an air restriction inside the evaporator probably caused by a dirty filter or dirty evaporator coil. ... Air Conditioners

I have/had 2 GE 8000btu wall air conditioners and at 3 years old, both of them within 2 weeks of each other had stopped blowing out cold air, just now the way a fan would blow. It almost seems to me that GE has purposely made these air conditioners to stop working properly at a certain time so I should buy new ones. I replaced one of them already with another brand, now I have to replace a 2nd one. I can't really afford to do this. Is it possible that they have both run out of Freon? Otherwise I

Great site. I have a Simplicity SPAC 8499-5 Portable Air Conditioner and it was working fine up until yesterday (~2 years old). The unit is running and the fan operational but while the green light for Cool/Dry is illuminated that actually cooling unit for the air conditioner is not kicking in. The system is just blowing air (like in Fan) mode. I have checked the water reservoir and it is empty and placed properly in the unit so the switch is engaged but no AC.

I have a fujitsu reverse cycle air conditioner,it wasnt working(not blowing cold air only room temp air like a fan).air con tech came over,re-gassed it,tried air con that day,worked fine.didnt need to use it for a few months,re-tried it,no cool air again,i am thinking of a leak.My question is the air con is about 10 years old,if cause of problem is a leak,is it worthwhile fixing it(i would need to pay someone parts and labour,could not do this job myself),or to just bite the bullet and get a rep


Hi,\015\012\015\012The A.C is 10 years old which is a ideal shelf life for the A.C. If there are any leaks I would never ever try repairing it at home becuase if there is a leak then that means that the entire GAS which helps in the cooli ... Air Conditioners

My haier room air conditioner (hwr08cx7) just stopped working. The power goes on, the electronic displays light up, but fan does not blow. I also cannot adjust the mode--fan, cool, energy saver, dehum. I can adjust the temperature/speed but it doesn't do anything. Using the remote gives me the same results. The air conditioner is about a year old....

Contactor not engaging to start condenser unit . When setting the thermnostat, i hear the click from the unit starting inside the house. Fans start and air starts blowing inside the house, but the condenser unit never starts. I tryed pushing the contactor by hand and then everything works find (cool house) as long as i keep the contactor pushed manually. Seems alike the 24 V (coil) bobine in the contactor is not been energize. When I tried the 24 V outside with a 24 V surce it worked fine. Thank


I would replace the contactor if you are getting 24 volts to the contactor and it isn't engaging therefore the magneto on the contactor is out and the contactor will need replacement. If you don't have 24 volts at the contactor then the transformer ... Air Conditioners

Hello, I have two Yokohama Split type air conditioners that work fine for cooling, but when switched to heat they just blow air at room temperature and then after about 1 minute go into a standby mode indefinately.
