Sounds like it may have lost power. Check the breaker and the fuse at the furnace. If they are all in the on position and working then it sounds like you may need a technician. If the display is blank on the thermostat you may also want to replace the batteries.

My conditioner wont work. When i turn in on heat comes out.. What should i do>?


Do you have central air? If so put the fan on auto turn AC to lowest setting fan should come on in a minute if not go outside to your condenser unit check for ice building up on the compressor or any of the copper lines if it is you need refrigerant. If not you may need to blow out the condenser with an air compressor or shut off power hose it out. Also, look for broken wires. If all else fails call your local service Provider.

I can't get my Air Conditioner to come on ?


Clean the filters of the air conditioner. Also, if the unit has been running for a few years without proper maintenance you must expect lots of dust in the evaporator unit. This is usually easy to clean with compressed air.

Good luck!

Honeywell digital thermostat won't turn off ac.


The Honeywell CT87 thermostat is a normal round thermostat, not digital and may have a sub-base installed with it that has a two switches on it. One is for Fan (Auto or On)and the other is for Heat, Cool and Off. Make sure the Fan switch is in the Auto position and the other switch is in either the Cool or Off mode. If you continue to get cooling, you have a short in the thermostat wire or a stuck relay in th indoor or outdoor unit. To test this, while the unit is running; remove the round outer ring on the thermostat by pulling it straight off towards you. You will find 3 slotted head screws that hold the thermostat to the sub-base. These screws are located at the 3 o'clock, 7 o'clock and 9 o'clock positions. Turn these screws counterclockwise with a small head screwdriver. They are held in place so should not fall and get lost. With the front of the thermostat removed from the base, the air conditioner should stop running. If the unit continues to run, you will need to have your A/C system inspected by a technician. If in fact your thermostat is digital, look to see how it is mounted to its sub-base and remove it. If the system stops, you may have a bad thermostat or the Fan switch is in the On position. Hopefully this will help.
