How Do You Unclog A Window Air Conditioner Drain?

Remove the unit from your window and its outer casing. Cover the fan motor and switches with a thick cloth to prevent water from getting in and causing damage. Using a hose, spray the drain hole. For thorough cleaning, use a low-pressure stream and direct the flow.

If the water is clean, you may remove the hose. Otherwise, rinse with a solution of vinegar and water mixture. Another option is to use a drain cleaner meant for clogged window air conditioner drains.

Mix it in a bucket using cold water, and use a small garden sprayer or beverage dispenser to apply it to the system. You can use this for large units as well as smaller units that don’t require an extensive cleaning process.

Plug the unit back in and turn it on. If you still see dirty water flowing from the drain hole then you need to repeat the steps above until no more dirty water comes out of the drain hole when you run your unit.

You may have heard of a flood in relation to cooling units. There is a small possibility that you could flood your unit when you have waterlogged the evaporator coil or if you are not carefully cleaning it. When the temperature of the water exceeds 100 degrees F, the chance of your cooling unit flooding is greater as well.

If things go horribly wrong and you flood your window air conditioner, do not apply heat or try to power it back up immediately. The best thing to do is shut it down safely and let the manufacturer take care of finding out what is wrong with your device and fixing it for you (I am speaking from personal experience).

Should I Remove The Drain Plug From My Window Air Conditioner LG?

This drain plug should not be removed under normal circumstances. If the air conditioner is being stored for the season or if a technician needs to remove the water, the drain plug allows water to be removed.

Repairing a window air conditioner is not very difficult. If you have some technical skills, it may only take as much time as it would in your home. One way to see if your unit is fixable is by turning it on and checking for a hum. It should run quietly for about 5 minutes before shutting off with an audible click of the breaker.

One of the most common problems, either from improper installation or overuse, is the drain plug assuming that there isn’t one present on the inside of the drainage valve body. If the drain does not work, you must locate the water in a way that allows you to drain it.

If your unit is on a window sill and there is no drain plug on the outside of your unit, then it’s likely that there is one inside. If so, remove the casing or cover and look for a large plastic or metal gasket where the water comes out.

Open up this gasket, reach your hand in and find the plug that drains out of this opening. Be sure to note where this plug goes again. You will need it when you reassemble your unit.

Another common problem threatening window air conditioners is those with digital controls. These are known as touchscreen units. These units have a unique feature called a resin heat sensor.

This sensor is used to tell the air conditioner what temperature it should cool to and the actual temperature of the room, thereby allowing for an accurate and consistent mode of cooling.
