Airconditioning not working - Honeywell Heating & Cooling

Sounds to me like a breaker has popped. In the main power panel, see if one of the breakers is in the center position.

Fredrich makes one which may work in sleeve or install a new unit with sleeve and put molding around hole in wall .

possible that the fan sensing unit is bad

Have you had the freon level checked. It might be low.

check your dimmer switch and fuses.

You might check the cooling fans on the condenser to see if they are running when the ac is on.If they are not check for blown fuse,or bad cooling fan relay.Do you notice if the ac cools better when running constantly,and the ac is not so cool when in traffic,stopping and going,and running slow?If so the cooling fan,or fans are not working.If the fan fuse and the relays check out fine,then replace the fan,or fans.If I can help any more please ask.roniecon@gmail.com

If the ac fan is not coming on the ac is inop. the compressor is bypassed. Check fuses and relays first.

i think check for possible malfuntion of condenser fan
