Air conditioning window unit not working.

Window ac not cooling 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. No matter which type of air conditioner you have a clogged filter restricts airflow decreasing efficiency and reducing the ability to effectively cool the air. If the fuse burns out again provide a dedicated 120 volt plug for the unit. Check the air conditioner power supply cord for any signs of fraying or damage.

Window air conditioners by room size knowing the size of the room you need to cool will help you determine how many btus you need. If it s leaking in other circumstances try cleaning or replacing your air filters. For wall and window air conditioners check the angle at which the unit is installed. The major difference is that you can install them inside a wall as a way to free up your window.

If that is the case fix it by replacing the fuse wire. This video shows the steps for partial or complete disassembly. Also this same information applies to through the wall air conditioners which are basically the same thing as window ac units. Check the receptacle with a tester or plug in a known working appliance such as a lamp or a fan to verify that the circuit is live.

The unit must tilt toward the outside from at least 1 4 to 1 2 inch in order to properly drain condensation from the base pan to the outside. If your air conditioner isn t turning on first check your unit outside to determine if the condenser is running. Too few btus means your unit has to work harder. Once the fuse has been replaced check the machine by running it again.

Too many btus means you could be using more energy than you actually need. The first step in cleaning or repairs will be to at least partially disassemble the air conditioner. If your window air conditioner won t turn on it may be that it is not getting any power. Make sure that the unit is plugged in and your thermostat is set properly.

A window air conditioning unit that is constantly cycling on or off can usually be traced back to a thermostat or temperature sensor that is on the fritz and no longer working the way that it should.
