Could be low on refigerant or you have a plugged filter. You have to let the ice melt before you check the refigerant to get an accurate reading or replace filter.

There are two things that make a central air conditioner freeze up, they are poor air flow, that means check your air filter, and your system is low on refrigerant, and that will take a serviceman to fill on refrigerant. For the time being set your thermostat cool/heat switch to off, and turn your fan switch to on. This will thaw out your cooling unit, and when the ice is gone you can switch the heat/cool switch to cool to resume cooling until you have figured out which problem you have.

I have a Braeburn 3200 and when the the temperature reaches the desired heat setting. The furnaces heat will shut off, but the fan will continue to run indefinetly. eventually blowing very cold air up


The fan relay is stuck in the on position. When the temperature drops the heater does not ignite because the fan is already running and ignition is locked out after the heat cycle starts an the fan turns on

Had ac on over night and it iced up on the inside behind the air filter out side temp. 75 inside temp 72 usually don't leave on over night and temp was 85 when we turned on


You might check the return air filters and see if they are dirty, also make sure the blower is working and your getting the normal air out of the vents. If that checks out, you will probably need to charge the system because it's low. If you call a technician out, make sure you turn the a/c off and turn the fan to the on position at the thermostat so to be sure your system is not froze up at all, otherwise the technician cannot do anything until it thaws. Two other things to check would be the vents after you know for sure it's not froze, this will tell you if your coil is clogged/dirty, and make sure the outside condenser fan motor is working too! Hope this helps and good luck.

We have a3 yr old Goodman CAPF3030B6AA Airconditioner and Furnace. The Air conditioner hasnt worked right all summer. Its 102 degrees outside and we can set the thermostat on 72 degrees and it will be...


A/C units have a design temperature of 90F. Now when the temperature is above 90F they start to have trouble keeping up. Depending on how well your unit is sized for the house, you will notice when the temp is over 90F. I don't know if who ever looked at your unit checked the refrigerant pressures since you said he checked the temps but I assume he did, however, it could possibly need charging.

My A/C (Carrier weathermaker 8000 hybrid) is not cooling properly


set the t-stat low and let it run for 5 minutes , stick a thermometer in the return air closest to the unit as possible until you get a good reading , then stick the thermometer in the cold air supply again closest to the indoor unit as possible let sit until it stops going down in temp.
this is called your temp difference and it should be atleast a 14deg. F difference from in to out. if its lower you have a refrigerant problem, Let me know how it goes.

GE Portable Airconditioner - Model APN10AA Serial # GG509122


Ours was leaking water. After taking the covers off,cleaning it,and draining all the water out, I started getting the same problem with the light coming on every 7 minutes. I actually added some water to the system till it was too full and then drained it out through the plug. The light still came on every 7 minutes until I turned the unit off and then unplugged it for a few minutes. I plugged it back in, turned it on and reset the temperature. It seemed to reset itself and kept running normally. BB
