The compressor relay is short and it continously running in all modes.You need to check this relay contacts to be short or the relay drive is constantly on.So check these units.

SOURCE: Compressor appears to kick in, runs for short time

It sounds like your unit may have a bad run capacitor or start capacitor and relay. Low voltage will also cause this problem. First you need to make sure that you have the full rated voltages at the unit, if you do, then, have the run and start capacitors checked out and the start relay.

SOURCE: Haier air conditioner will not kick on to air

A few basic principles for air conditioner troubleshooting. For both central home air conditioner or window air conditioner, the first thing to check is whether the unit is getting proper power. If the unit uses 220 volt power be sure that the proper voltage is getting to the unit. Same for 110 volt units. A voltage meter can be used to assure that the voltage is correct.

For window air conditioning units the voltage can also be checked before and after the thermostat. If voltage is being supplied to the thermostat but not from it then the thermostat probably needs replaced. This is a fairly common problem. Another place to check is the fan motor voltage. The fan on window air conditioners runs both the indoor blower and the condenser fan. If that motor fails than the compressor may run for a short time, but will overheat and shut off. Continued operation like this will result in compressor failure. This motor can be economically replaced for larger window air conditioners, but for smaller ones the cost of replacement will be more than a new unit.

Central air conditioners for the home are more complex and there are more things that can go wrong. As with the window air conditioner the thermostat can also be a problem. The central air conditioner thermostat will only have 24 volts going to it. So don't look for high voltage there. Some units the voltage will be coming from the outdoor unit and others the voltage will be supplied by the indoor air handler or furnace. Most home central air conditioning will be supplied by the indoor air handler or the furnace. If the air conditioner is for cooling only the unit will usually have only two wires going to the condenser unit. Make sure that you have 24 volts across those wires.

The next thing to check will be the indoor blower. If your thermostat is calling for cooling then the indoor blower should be running. If there is no air moving across the indoor cooling coil then you will soon have a big block of ice formed on the coil. This can happen for a few reasons. The indoor blower is not working, the air flow is restricted and not allowing air to move across the coil. A clogged air filter would also do this. Or the outdoor condenser unit has lost the charge of refrigerant.

Finally and worst of all is when you have a complete compressor failure. Often when this happens the compressor will "lock up" or not be able to turn when power is supplied to it. Overheating or lack of lubrication are usually the main causes of compressor failure. Overheating can be caused by the outdoor coil around the compressor getting clogged with dirt, leaves, or grass. Loss of the refrigerant charge will also cause the compressor to overheat. It is the cool return gas coming back to the compressor that helps to keep it from overheating.

As you can see there are many things that can go wrong with an air conditioner and I have not come close to exhausting the possibilities here. I have just touched on the most common problems in a very basic way.
There are some basic trouble shooting things that can be done very easily. Most problems are above out of the range of comfort for many homeowners and professional help should be consulted before any attempt is made at repairs. Remember also, that the release of refrigerant gases into the atmosphere is a federal offense in the
US. Proper care must always be taken to minimize the release of any gases. A license is also required to handle refrigerants. Make sure that the professional you call has the proper certifications to handle refrigerants properly.

Air handler fan cuts on runs a few minutes and then cuts although thermostat is set to off.


your thermostat could be wired in to a energy recovery venilator which will bring the unit on for a certain amount of time every hour some thermostats have recirculate mode which will do the same thing to help filter the air

My air conditioner starts blowing like a fan before my apartment is cooled off, why does it kick off and on like this?


When you first turn it on the fan runs and after a few minutes the outside unit comes on, once the outside unit comes on it take time for it to cool the coils which cool the house, And a/c does not really cool the air,It removes the heat that is in the air.

Amana Cooling Condensing Unit fan won't kick on


be aware that not repairing this asap that you are causing yourself more problems First I would change out the fan capacitor and see if this could be the problem. Secondly if the capacitor isn,t the problem change out the motor . By continuing to allow the system to cycle like this the compressor will take a dive on you costing more . Good Luck

Fan slows to about half speed when heat cycle kicks in


The heat fan speed is slower than the cooling speed. About 300 rpm less.
You may not have a problem.

Sharp Air Conditioner. Model # AF-S85NX. Does this A.C. fan cycle on & off in the auto cool mode or does remain on continuously. I need a small A.C. that cycles off and on with the compressor.


If you set you r AC to FAN mode the unit will not cool, it only runs in the indoor but the outdoor will off. If you set to AUTO the unit will cool but the indoor blower will automatically run slower when the room is cool or attain the room temp. setting. If you set it to COOL the fan speed is fix depending on your setting and it also operate in cool.
