Air Conditioner Doesn’t Cool Air Conditioner Doesn’t Turn On If your room or window air conditioner doesn’t cool or turn on, this expert guide to AC repairs will help. Most problems with window and room air conditioners can be categorized under one of two symptoms: they do not cool sufficiently or they do not turn on at all. Here is a closer look at how to troubleshoot and repair these issues. Air Conditioner Doesn’t Cool A window or room air conditioner that doesn’t cool may need to be recharged with refrigerant, but the chances are good it simply needs to be cleaned. You can do this yourself, which involves disassembling the unit, or you can call an air-conditioning professional. Before attempting the work yourself, consult your owner’s manual and make sure you have the right skills and tools to handle the task. Here is what a typical manual advises: 1Unplug the unit and carefully remove it from the window or wall. Put the air conditioner somewhere outdoors or in the garage where you can work on it.

2Remove the grille and filter and unscrew the metal case (taking care not to damage the coil’s fins). 3Wash the filter thoroughly or replace it with a new filter; most filters are readily available at most appliance stores. 4Using a vacuum with a soft brush attachment, clean the coil’s fins. 5Spray water back through the fins from the fan side (protect the wiring and the motor with plastic). 6Clean the unit up with a rag, making sure all drains that allow condensed water to drip away from the unit are open. Allow it to dry thoroughly. 7Lubrication. While you have the unit apart, lubricate the motor according to your owner’s manual. 8Finally, reassemble and reinstall the unit. Window and room air conditioners draw a lot of electrical power, which can lead to less than peak performance or even complete failure. If your room air conditioner doesn’t turn on: 1Be sure the unit is plugged in and turned on. 2Check that the outlet works by plugging in a light that works (only for standard-voltage models—do not plug a light into a 220/240- volt receptacle).

3If the light doesn’t go on, the circuit has probably overloaded—check the electric panel or fuse box and reset the breaker or replace the fuse. 4If the light works, it’s likely that the air conditioner’s switch is faulty or the thermostat needs adjustment or repair.jeep yj air conditioning unit 5Be sure the thermostat is set to “cool” and below room temperature.car ac repair spokane wa 6Refer to the owner’s manual for thermostat repair. 4kw ac unitIf repairing the thermostat doesn’t solve the problem, unplug the unit and call an air conditioner repair person.

In most of the cases, the problem is a minor one and can be taken care of at home without getting a professional help. A little general knowledge about window air conditioners will help you to understand and rectify the associated problems in a better way. So, before you toss your old AC unit or call a repairman, check these five common problem areas and give DIY repairs a try. Check whether the power cord is completely plugged in; sometimes outdoor outlets or older outlets don't secure the plug tightly enough and need to be tended to. Then check the cord to see if there are any visible cuts or breakages on it. If the power cord is cut, safely unplug the unit and take the appropriate measures to fix the broken areas. If your window unit’s button interface is worn and can’t be trusted, you can also consider buying a cheap universal AC remote or replace the worn switch.

If you suspect this is the case, it means the unit is not broken, just that you have no way of communicating what you want the machine to do. A window air conditioner won’t turn on if the fuse of the main power source to the unit has blown. If that is the case, fix it by replacing the fuse wire. Once the fuse has been replaced, check the machine by running it again. If the fuse burns out again, provide a dedicated 120 volt plug for the unit. If the air conditioner draws power from a circuit shared by other appliances, it can’t draw required power supply and will blow the fuse repeatedly. By providing its own high-voltage plug, it can run smoothly with fewer interruptions. NOTE: Because of the power demands of an air conditioning unit, it may trip the safety buttons on certain outlets and the plugs will need to be reset to eventually restore power. Always check this as well. A similar protocol should be followed if you have a circuit breaker. If your AC won't turn on, check to see if the breaker has been tripped.

If so, reset the circuit breaker and start the machine again. If it goes off again, you may need to rewire in order to provide a 120 volt circuit that operates only the AC unit. Check the temperature of the thermostat on your unit. If it the unit is set to "heat," it won't turn on. If it is set properly, try lowering the thermostat slightly to see if it makes a difference. Sometimes the thermostat gets stuck, but you don't know because it appears to be set properly. This is why it is important to make adjustments as you troubleshoot. If adjusting the thermostat doesn't make a difference, you more than likely have an air filter issue. When the filter becomes dry due to dirt accumulation, the thermostat can get stuck and the unit will stall. You can fix the problem by cleaning or replacing the filter. At times, the filter can even get stuck from accumulated debris, and if this happens, the window air machine can’t operate as the evaporator coil freezes. That is why checking the thermostat is such an important troubleshooting step.
