If the fan and compressor are running then the thermostat is doing its job.

Auto/On set to ON. Fan runs.


Sounds like the thermostat, the way to verify is to unplug indoor unit, remove thermostat, take pic of wiring with phone or label the wires as to the terminals. Carefully twist the yellow,(Y) Red (R) and the green (G) together. Plug the furnace back in, if the unit operates normally, replace the thermostat. I am basing this on the fact that the blower speed is changing. This could also be an anomaly within the circuit board in the furnace section, not likely though as the outside unit (condenser) is not controlled n by the indoor board unless this is a heat pump. hope this helps.

Download this illustration and then using a good multimeter start basic troubleshooting.


All residential window air conditioners have a cooling system made up of four primary components, a compressor, an evaporator fan, a control or switch, capacitor.When the thermostat is calling for a colder room temperature the compressor is energized. It is normally very quiet. The evaporator is always located on the front of the air conditioner. It also has silver fins. Be sure it is clean. Use a foaming type cleaner and rinse with plain water. Because the evaporator is absorbing heat, it is very cold to the touch. The temperature drop causes any humidity in the air to collect on the evaporator - sometimes called sweat. There is a fan inside the air conditioner that circulates the air for the evaporator and condenser coils. The circulating fan and compressor are running simultaneously. The fan motor has two fan blades attached to it on either end. The fan blade on the inside part of the unit continually draws room air over the evaporator coils, which are cold. The fan blade on the outside part of the unit continually draws fresh outside air over the condenser coils, which are warm. Because the evaporator coils are cold, they cause moisture in the room to collect on them, much like a cup of ice water on a warm, humid day. When the amount of moisture increases, it begins to drip down off of the coils into the bottom pan of the air conditioner.
If the compressor fails to start or the fan you may need to replace the capacitor.
You may need a hard start kit.

Thermostat control The thermostat on a window air conditioner works by sensing the air temperature entering the air conditioner. As the air entering the unit reaches the set temperature it will cause the compressor to turn off. The blower may continue to run depending on the selection chosen on the control panel. Digital thermostats work on a similar principle but display a more precise temperature.
Test for continuity with the multimeter between the two terminals . Warm you should read continuity (contacts closed). If not change it.
Selector switches The air conditioner selector switches allow the user to choose the fan speed. The compressor always runs at the same speed regardless of the settings. If low cool is chosen, for example, the fan runs at a slower speed but the compressor still offers the same cooling capacity. There are other switches to control louver operation and other features on some units.

The air conditioner is on but is not cooling the fan turns on and all but it dosnt cool


possible causes thermostat stuck open/ compressor not working problems related to compressor may be capicitor or the compressor itself.

Compressor continues to run for another 5 minutes after the fan has stopped. Air conditioner cools fine.


sounds like the "extended run timer" is somehow hooked to the compressor circuit instead of the blower fan circuit. This may appear after installing a programmable or digital thermostat. check configuration.

Thermostat slow to turn AC compressor on. fan comes on but takes 5 min. before compressor comes on


Most a/c's have a 5 minute delay before the compressor turns on and they will do the same when changing from cooling or heating to cooling.

Will run and cool until the thermostat turns it off and will not start back up. Inside fan continues to run. Compressor is completely dead.


Dear jack289,
The thermostat is not working properly. When thermostat cutsoff the compressor Please turn the thermostat knob to higher setting if compressor starts working then please change the thermostat. The fan will run continuously since only the compressor is controlled by the themostat.
Regards,

The Air conditioner are good only the adjustment of thermostat are the problem, select the thermostat in lower #3 you observe the thermostat will off in such time temperature reach to #3 If you full adjustment the compressor will not off.
In fan selector the compressor will autamatic off because no connection attached fan only .

Cooling


Check if the condensar ( outside fan unit) is getting enough free ventilation. IF there is no free air flow you will mostlikely be triping the unit due to short cycling. Ie the unit is pulling its own discherge air causing the compressor to trip due to high back pressure
