Lennox air conditioner is blowing hot air

My air conditioner is on and the fan is blowing but the air is not cold. I have tried to press the blue reset button on the condenser outside but nothing happens. Is there something else I can do?

Check your coils for ice, check your breaker and fuses for condensing unit, and is your condensing fan running? If not, you either have a bad fan motor or capicitor. After you hit the button, and wait for it to time out, (you should hear a click) take a butter knife, and spin the fan if it is not moving. If the fan start spinning by itself after your assistance, you have a bad capacitor

The blue snowflake is for the AC. The 3 fan icons are for low, medium, and high settings. The icon with the cup with over flowing water means empty the water tank. The cup next to the snow flake is the dehumidifier. The cup next to that means tank is empty and the clock is the timer. If the front part is only blowing out hot or warm air I say you got a broken one unfortunately. The back part blows out hot air which is why there is an exhost hose attachment.

When I press the button to change the speed of the fan it does nothing, and continues to blow at one speed and it is just about equivalent to the speed of the slow option...any ideas why? Also it will run...


Is it new? There may something wrong with the electronic circuit board not allowing other fan speeds. Try unplugging it for a while and try again. There is a temp sensing bulb somewhere on unit most likely on front where hot/warm air from space enters unit. Make sure you are not recycling cold conditioned air back onto sensing bulb.

2 year old Coleman Mach III tapping and not blowing cold air:


Make sure the condensor fan is blowing through the condensor on the roof. It sounds like the compressor is fighting high head pressures after running a bit.. After so many attepts, or if it suceeds in operating the load trips the circuit breaker.. Make sure the condensor is clean and air is passes through it from the fan. Just for clarifiication the condensor is the coil that gets hot and the evaporator is the coil yat create the cold air. Good Luck, and if you will, let me know how it turns out. Good Luck. Ned

Lennox air unit not blowing cold air


your fan motor outside is going bad, have a service company change it out for you.

the motor stopped working and that overheated the compressor shutting it down on thermal cutout, and it will only come on once it cools down

If the fan blows cold air the compressor is already on.

Comp shuts off


Coils could be dirty. Compressor could be getting too hot and cutting off. Will have one fan motor that turns condenser fan and evaporator blower.
