Having problems with your Air Conditioners ?

My Maytag portable A/C will blow cold air for one cycle, then after about five minutes it just blows room temp air and never gets cold again. If I turn power off then back on it does the same thing over again. already drained the water and cleaned the filter.


Answers :

Cleaned the filter screen or the coils? There are two coils. The evaporator coil and the condensor. There is the "filter screen" in which you can clean which is located in the back top portion of the panel that is easily accessible. However to clean the coils you need to remove ALL the back screws from the back cover and remove the entire back panel. There you will see both coils. From your statement it sounds like there isn't sufficient airflow over your coils and the freon cannot release its cooling effect into the hot air thus it tends to ice up on the coils. You need to wash out all the lint dust from both coils. You can do this with with air conditioning coil cleaner or for starters use a stiff paint brush and vaccuum. Clean as much debris off as you can, then run the unit. It should last longer than your previous five minutes. If it doesn't work then your in trouble. There is a metering device called a TXV or expansion valve that may have failed causing the freon not to flow freely thoughout your system. However it is a rare occassion that it fails so it should be that the coils are dirty. GOOD LUCK

Our 1992 brivis buffalo electronic pilot relighter does not ignite the furnace when you turn it on at the thermostat. Have tried turning it off at the power and back on again, makes a ticking noise for about 30sec then stops. Have taken the cover off to have a look, the pilot light is still lit and doesn't appear to be anything electrical. It will also intermitantly start blowing cold air and the only way to stop it is to turn it off at the power point outside. Could it be the ignition electr

The heat pump is not working properly. i think the problem is in the switch mechanism. when the heat is on and the thermostat is turned up it blows cold air. sometimes the compressor turns on and off. if you turn the other switch to the off position, then turn the thermostat up then turn it back to heat. it will blow hot air. if you then turn the thermostat down, wait till it turns off, then turn it back up, it will blow room temp air and sometimes the compressor will turn on.

I have a Heat Controller EKTH15-150J PTAC. Of lat,e toward the end of winter here in southern Missour,i the unit while in heat mode has been randomly blowing cold air. Often you can shut off the unit and let it sit for awhile and when you turn it back on it will come up heating again. A couple of years ago I replaced the control board that had been killed by a lightning induced power surge with a RSKP006 control board kit. It has run fine since, until the last few months.

They did test O.K. at first but the unit would still not come on.

It is over 100 degrees outside with very low humidity the last few days.(Los Angeles) ; since it's a wall a/c, of course 1/2 of it is outside in the heat.

At 30,000 miles my then 8 or 9 month old chevy 2500hd 4wd pickup truck air conditioning started blowing hot air on the driver side (the passenger side was still cold). I turned the truck off and back on and it began blowing normally for a few days and then it would do it again. A year or so later the heat on the driver side went out totally (passenger side worked properly). So now the driver side blows cold air constantly. A few months after that the blower quit working all together. Now at 185,

Our airconditioner has the code C6 on it. It has cut out and displayed that code. We were instructed to turn it off at the power board and turn it back on, which we did. It went back on again and tried to work but it wasn't really cooling down the air and then after 15 minutes it cut out again and displayed the same code. We don't know what the code means as there is nothing in the instruction booklet which indicates any codes at all.


I previously asked you, if the C6 appear on the unit or on the hand held remote. I contacted a friend of mine who is a service technician for the LG Split System units and he advised that it's an error code that can only be solved by a LG trained ser ... LG LA185HV Split System Air Conditioner

Now, it is 50 degrees in the house. Tonight it will be around 16 degrees outside. How can I get my heat pump to produce warm air?

No heat My 7500 zoneline will not provide heat consistantly. I can unpplug the main power source to the control boards and plug it back in, ,and I will then get heat. If I turn down the thermostat (80 to 70), then turn it back up, I do not get heat again, only cool blower air. Is one of my control boards bad? Thanks.


It sounds like it could be the tstat itself. Unless you use a voltage meter to take some readings it's hard to determine if it is a board. The best thing for you to do is remove the tstat from the system and manually operate it with a jumper wire t ... GE Air Conditioners
