If the capacitor is bad replacing it is just a mater of moving the wires from the old one to the new one and mount the new capacitor securely in place. In replacing a capacitor it is recommended to replace it with the same rating as the one removed.

If the capacitor is bad it will not prevent the compressor from getting power. Is the compressor trying to start at all. If the compressor is running and you have no cooling the system could have lost the charge of refrigerant.

SOURCE: Blowing hot air, compressor not kicking on, just fan ? ?

are you speaking of the outside fan or inside? compressor should be a little warm but not boiling hot. the unit could be low on freon. if low it will run a while but the compressor will overheat and shut off leaving the fan running by itself ouside. if nothing outside is running check power. if you have power check the contacted outside to make sure it's pulled in. contacters are bad about going out on goodman untis. Also ants can get under contacts.

No, this cycle cannot be shortened due to the simple fact that this feature is in place to protect your system. Even if it could be, I wouldn't recommend it.

Why does the compressor for the air conditioner not go on even though the circulating fan does.


What sort of air con is it? If its a split or ducted with a separate outdoor unit, does the outdoor fan start ?

Only the compressor is running but not the fan


if the fan next to the compressor is not working you need to replace it otherwise the compressor will get hot due to no cooling air above also make sure the condensing coil is also clean for proper circulation you should have your unit working if you follow this steps...good luck

A/c won't stop running and no cool air


There seems to be a problem with the wiring of the thermostat. Apparently the thermostat is calling for cool (if wired properly), but is not being satisfied. The thermostat is just a switch. When there's a call for cool, the thermostat sends 24-28 volts to the contactor (inside the condensing unit to start the compressor and outdoor fan). The indoor fan is energized through the fan relay (inside the air handler). When the temperature in the conditioned space reaches the set temperature,then the thermostat cuts the power to the contactor and it stops the compressor and outdoor fan. Check that the compressor is actually running, if not, check for 24-28 volts on the wires feeding the contactor, if there is, and the contactor isn't closing then the contactor is defective. If the contactor closes and the compressor doesn't come on, check the capacitor. If the capacitor is good then check your compressor motor. I suspect you have an improperly wired thermostat

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.

Compressor starts then stops after maybe 3 mins


Any error codes? If not there may be a mechanical fault with the compressor/inverter. The unit is possibly short on refrigerant, so the compressor is not getting enough suction cooling from return gas, so may be clicking off on its internal over temp klixon.

all the best

Compressor will not start.


Usually short cycling means that High side pressure is getting to high (due to not working condenser fan, or dirty condenser coil), or low side pressure is getting too low (might have low level of freon or restriction in sealed system). low side would drop dramatically if indoor blower is not running, so if air is not circulating thru evaporator coil, coil will freeze up and low side would be much lower then normal. Here is video how I found issue with package AC not coming on. Thermostat call for cool, but condenser would not come on, indoor blower runs ok.

Shut off the cooling and leave the fan in the on position. If the A/C cooling coil is frozen over it will stop air circulation. After you shut the cooling off look down through the fan on the roof top unit and look for any sign of ice on the big line going to the compressor. This would be a sign of the frozen A/C coil. After about an hour or so you should start to feel air movement.

To prevent the coil from freezing up operate the fan in the on position while the air conditioning system is in the A/C mode. Not automatic.
