Question about Fedders A&B Chassis A1A07W2B Air Conditioner

Light gray smoke

There is a light-gray, odorless smoke coming from my ac unit. It still blows cool air, but it starts blowing smoke within a minute of being turned on. I noticed that the smoke stops when the temperature control is low (almost to the point where there is no cooling). It has been used rather heavily in the last week, due to a recent heat wave. I don't notice any leaking (at least not on the side facing in), nor is it making any odd noises. Any suggestions..? ^^; Thanks in advance! Byron

Geeze you peeps :P the key here is ODORLESS --- freon, and any smoke from electrical will produce an odor. if its odorless its humidity. Thats all. nothing harmfull. Yes, thats right, water vapor. seen it a million times. it has to do with temp inside/outside, and humidity inside/outside. good luck diagnosing a real problem

    You are spot on, sir. The effect comes from reaching the dew point. Kudos.

The "take" guy is right, and I know from first hand experience. I knicked the refrigerant line trying to put extra drain holes in the unit and I saw all the gray odorless gas fill my daughter's room. It stopped shortly. My cousin who fixes AC units for a living told me, there is no way to fix it, and U have to buy a new one.

The smoke is refrigerant or freon which is a nearly odorless gas. This happened to me and after two days of the smoke my airconditioner has no more cold air.
I dont know if its harmful I am sure the freon people will say no but I think all chemicals are harmful to some degree (thus cancer) so try not to breath it (get it to the shop and dont use your air). If it is a pin hole you could have it for a long time eeking out or it could be on and off. I noticed mine came after I changed from defogger to air high setting, almost like it opened the hole wider by changing settings

Well it could be just frost or like fog because of the cold air it is producing.But at any rate to be safe it definitely needs to be checked out. It could cause a fire. If it is a bearing in the blower motor getting hot and going out it could cause a fire. If it is freon leaking then it wouldn't take long until it wouldn't cool any more. And your eyes would probably be burning because of the gas. I know we used to use window units and they would blow out frosty foggy air sometimes. The bigger units especially. Not much you can do about that. Won't hurt you anyway. But please check it out.

Sorry to say but your ac unit have a broken line, the smoke that you see is refrigerant gas, and the hole is very small, so only when the compresor is on you notice it, soon there will be no more refrigerant and the smoke will stop, but the cool to, buy a new one....goo luck

It could be that you are just seeing the fog from cold air coming from your vents. If they keep cooling, don't worry about it. Let me know. kstfas

Why does my MR. HEATER 125KT blow continuous gray smoke Total use about an hour and a half? Puts out a tiny bit of heat and within 10 minutes drip fuel out of lower or bottom shelf.


Do not try to use this unit as you have fuel leaking and could cause an explosion or fire. You have a leak some place and the grey smoke tells me that it's trying to burn more fuel than it should.

Frigidaire AC window unit, model fam185r2a (18,500 BTU) only cools for a few minutes before it cycles off and just fan blows. Then a few min later cool air cycles back on. Is this a thermostat issue?


The window units normally have a sensor thats attached to the front of the indoor coil. This controls the thermostat. I usually pull this sensor away from the coil because it stops cooling before the room is cool. It is attached to the cold coil so it senses the coil temp, not the room temp. You can normally see it when you remove the air filter. Don't break it! It may be a wire or small copper tube

Odorless smoke coming out of my amana air conditioner is the problem odorless smoke coming out of my air conditioner wath is the problem?


That's a cool mist, like a fog. It's not smoke and occurs when the outside humidity is extremely high.
Be sure the air intake filter is clean and if it continues for a long time, raise the temperature setting of the AC a couple of degrees and allow it to run, until the mist clears. It harmless, so don't worry about it.

Thanks for choosing FixYa.

My samsung split ac is not cooling. there is air blowing no cool air .before the roomwill get cooled within 30 minutes.


could have leaked out all its gas. if its an older unit it may be cheaper and easier to replace the whole unit. will make a buzz noise occasionaly from the outdoor unit. this is the compressor tring to pump the gas that is not there. check if the fan on the outdoor unit turns on.

My kenmore window unit AC started blowing a white smoke like substance. It seems to be cooling fine. What is this and is it a concern?


The two things it could be, #1 - evaporator leaking refrigerant - unlikely if unit is still cooling o.k. because window units do not hold a lot of refrigerant and if there is a leak bad enough to blow smoke it would have stopped cooling by now. #2 - the humidity is high and the unit has cooled the air right at the discharge down below the dewpoint, a common occurence in window units and automobiles due to the short duct distance from the evaporator to the air outlet whereas with central air systems having longer duct systems the air gains more heat before being discharged into the room.

AC cools then blows hot air, tempature needle goes up & down


Sounds like the thermostat is trying to stick,and is causing the engine to over heat,therefore condenser is not cooling the freon down enough to cool.Have the thermostat changed and the cooling system bled out,this is most likely the cause.

Maytag M6Y18F7A Air Conditioner troble light turns off


you have to open the unit up or atleast see if the fan is failing. The blower motor is usually a double shaft and cool the compressor and also blows the air across the evaporator. Look for the air to stop blowing then the compressor to shake from overheating.
