Question about LG DLE7177 Dryer

1 Answer

Using side exhaust

The manual is somewhat unclear about this - I want to exhaust the duct to the side of the dryer, but is there another (shorter) duct I need to purchase to connect back to the blower? I can't see how the existing duct can be used at all.

What are the maximum number of joints a recommended in the dryer vent pipe for these electric Ge profile dryers.


Codes typically require that the dryer duct be no more than 25 feet long. It should be 2.5 feet shorter than 25 feet for every 45-degree bend and 5 feet shorter for every 90-degree bend. If the duct is more than 25 feet in length, the system requires a booster fan or a high-output dryer. Ducts should be smooth metal with a minimum diameter of 4". Flexible ducts shouldn't be used, since they collect more lint and can easily be crushed, impeding airflow and potentially starting lint fires. The ducts shouldn't have screws or connectors, which could collect lint, blocking the flow of combustion gases. Backdrafting can occur if the ducts are blocked, sending harmful carbon monoxide back into the home.

Tip

Dryer Takes Too Long to Dry


This advice is for problems with a dryer that runs and heats, but takes entirely too long to dry.

MOST dryer heat related problems are due to poor ventilation. As your clothes dry, warm moist air is exhausted out the dryer exhaust vent ducting. If you have any kinks, excessive bends, sags, or excessively long ducting runs, this can create choke points for lint to accumulate. Once the lint accumulates, it begins to collect moisture. As it collects moisture, it will act as a sponge and collect more lint until the dryer becomes completely clogged. Left in a clogged state, the dryer begins to overheat and dries less efficiently. You may notice longer dry times or an excessively hot dryer. Eventually the dryer heating circuits will fail which will require the replacement of failed components ($). This can also become a fire hazard if the lint becomes so backed up that it begins to collect on, or near, the heating element.

If you have not checked the dryer ventilation any time recently, now may be a good time to do so. I recommend checking it about once per season to ensure it is not obstructed. Make sure you are also using the SEMI-RIGID METAL type ducting. It resists crushing, kinking, resists heat better, and resists rodent infestation.

NOTE: If you are using plactic ducting, get rid of it. It collapses easy, rips and mice will chew right through it. Mice are notorious for building nests inside dryers. Give them a warm place with bedding material and they will make it a home.

Make sure the exhaust vent is at least 12 inches off the ground. This will deter mice and others pests (like snakes or birds) from entering the dryer exhaust from the outside. If you place a cover on the vent, make sure it is of the louvered variety. Do not use screens. They will collect lint and clog easily. Keep in mind, along with cleaning your lint trap after each load, you need to check the outside vent periodically to ensure it is not obstructed.

An easy test to determine if you have an exhaust problem is to remove the dryer vent hose from the back of the dryer. Turn the dryer on and attempt to dry a load of clothes as you normally would. The air leaving the back of the dryer should be forceful and warm (about 140 degrees). If the air flow is weak, you need to check the dryer interior. In particular, the blower fan housing. If the air flow is normal, and your clothes dry as they should, reattach the hose and run the dryer again. This time, check the exhaust vent where it exits your home. Again, the air flow should be forceful and warm. If not, you have a clog somewhere in the ventilation ducting which will require cleaning.

Check the ENTIRE run of the exhaust ducting. Make sure it is not kinked or crushed anywhere which can cut off air flow. Exhaust vent ducting that runs through attics and under crawl spaces are the worst. In an attic, air flow is forced in an upward direction in which gravity will always win. Lint will accumulate in the tubing and cause the dryer to work less effficiently. You will need to remove the dryer and clean the ducting periodically. Crawl spaces have similiar problems. If installed properly, the ducting should be suspended from the joists and not lying on the ground. However, over time lint can accumulate and cause sags. These areas will accumulate lint and eventually choke off the airflow. Again, it is recommended that you clean the ducting thoroughly each season. Leaving the ducting on the ground isn't the answer either as this gives ready access for rodents to chew through it.

In addition, many home owners unknowingly will push the dryer against the wall and crush the hose behind it. This will also clog the vent and make the dryer inefficient. Leave about a 1 foot space behind the dryer for proper ventilation and ensure the vent hose does not get crushed. Semi-rigid hose will prevent this from happening.

The general rule of thumb when it comes to dryer exhaust ventilation is the SHORTER and STRAIGHTER the run, the better. The longer the distance and the addition of more bends creates resistance and makes a dryer less efficient.

IMPORTANT: Exhausting a dryer freely into your home WITHOUT ducting (i.e., into an attic, crawl spce, or in a laundry room) is NOT recommended either. Dryer vent exhaust contains moisture. This added moisture, coupled with the warm air from the heating circuits will add humidity to your home and creates a breeding ground for mold and mildew. DO NOT run an unvented dryer in your home like this. It can become a health concern.

If you have any questions, please let me know. I have seen these problems many times. I hope this information is helpful.

My dryer is not heating much and there is a smell of electrical burning. This is the first time I have used the dryer since having the dryer exhaust duct cleaned. Could the cleaning guy have somehow...


Hi,

It sounds like the exhaust duct may have kinked when he slid the dryer back in place...that would make it run hot and it would not dry...
Pull out the dryeer from the wall and then try it...if it work then slide it back acrefully making sure that the exhaust duct stays open...

Dryer takes too long to dry. Clock sometimes will jump from shorter drying time to longer drying time. It is about 7 yrs old. Exhaust is clean to the outside of the house.


Hi, Frequently there's an obstruction in the vent duct from the dryer to the outside of the house. For the dryer to heat properly, the duct must be clean and clear of lint or any other substance. Although this isn't a common problem, one of the thermostats that controls the temperature in your dryer may break and cause the dryer to heat poorly. If so, you need to replace it. The thermostat is usually a small, round, black device mounted to an oblong steel plate. The plate is mounted to the internal ductwork with two screws.

DOES NOT DRY CLOTHES ON ONE CYCLE STILL HAS HEAT MODEL DWSR483EBOWW


The most common cause of extra long dry cycles that I have found is RESTRICTED DRYER VENT DUCTING!!!!!!!!!
Make sure you thoroughly clean or replace the ducting connected to the dryer exhaust tube, if at all possible, DO NOT USE FLEXIBLE DRYER DUCTING, ESPECIALLY NOT WHITE VINYL FLEX DUCTING!!!!!!!
If you have to use flex, make sure it is as short of a run as possible, and no sagging, no crushed or restricted areas, and pull taught once you have made your run, to limit the ridges, thus reducing restrictions.
THE BEST DUCTING IS SOLID TUBING!!!!!!!!!!
Refer to your installation manual for manufactures recommendations.
Have a great day !

My dryer wont come on, it is only 2 years old, no sound no nothing, I tried putting on a new plug this didnt help. Any ideas?


First,use a volt meter to make sure you have 220 volts coming to the dryer.
Second,if voltage is ok,remove the back panel from the dryer and check continuity on the thermal overload fuse attached to the exhaust duct. The exhaust duct is part of the dryer. The fuse is about 1 and 1/2 inches long by 1/2 in wide and white in color. It is on the left side of the exhaust outlet.

Before assuming you may have a component failure, do a little routine inspection of the dryer and exhaust vent ducting.

If your dryer performance has been failing (i.e., clothes taking longer to dry), it may be because the exhaust ventilation ducting is clogged. If you can't remember the last time the exhaust vent was cleaned, or if it has never been done, this can contribute to dryer performance problems. All dryers need proper air flow in order to dry properly. If the ducting becomes clogged, the heating circuits will actually overheat, causing poor drying results and eventual failure. This usually results in the Thermal Cut-Out (TCO) blowing or the Heating Element failing or BOTH. When these components fail, they must be replaced.

There is no lint screen that catches ALL the dryer lint. Some lint will always get exhausted with the moisture from your clothing. If the exhaust vent is kinked or has excessive bends that create choke points, lint will accumulate in these points. Once the lint starts to accumulate, the moisture from your clothes starts to collect in it, and more lint get trapped. This eventually creates a clog. The Rule of Thumb: The SHORTER and STRAIGHTER the exhaust ventilation ducting, the BETTER.

A simple test to determine if you have a clog somewhere is to remove the dryer hose from the back of the dryer and attempt to dry a load of clothes as you normally would. The air escaping the back of the dryer should be forceful and warm (about 140 degrees). If the air flow is normal and the clothes dry as they should, then you need to inspect the ducting thoroughly from where it leaves the dryer to where it exits your home. It should be clear with no kinks or clogs.

If your vent line runs under a crawl space make sure it is suspended above the ground and has no sags where lint could collect.

If your exhaust vent runs to an attic, this is a poor design that gravity will always win because of the resistance the blower fan meets trying to push the exhaust up the wall. The lint will eventually collect in the ducting going up the wall and have to cleaned out from time to time.

Also, make sure you don't crush the dryer hose behind the dryer when you push it up against the wall. You should always leave plenty of space behind a dryer to prevent this from happening.

Rodents and birds are anotehr cause of dryer problems. If they have access to the outside exhaust vents, birds will build nests in them and mice love a warm place with plenty of bedding material (lint makes a nice nest). Make sure the exhaust vent is at least a foot from the ground and use a louver type cover to keep pests outside. Do not use a screen. It can resist air flow and clog.

In addition, you should be using semi-rigid metal type ducting that resists kinking, crushing and rodent infestation.

If the air flow is weak, then you need to inspect the dryer INTERIOR to see if the air blower is working properly and is not clogged. It is important to keep a dryer checked routinely. Failue to do so can lead to component failures and is a potential fire hazard.

If you have questions, please let me know. I hope this helps you.

Dryer is not drying. Lint is not collecting on


There is no lint screen that catches ALL the dryer lint. Some lint will always get exhausted through the dryer vent exhaust ducting along with the moisture from your clothing as it dries. If the exhaust vent remains unobstructed, all the air and lint will be blown out the end of the dryer vent exhaust.

However, if the air meets any resistance from kinks, excessive bends, or sags, moisture will build up inside the dryer vent exhaust causing the lint to stick to the interior walls of the vent hose. Over time this lint builds up and forms a clog. With a clog comes condensation and longer dry times. The dryer will continue to run inefficiently and cause the heating circuits to work harder and overheat. This will eventually lead to a failure of the heating circuits. If you are seeing condensation inside the dryer, it is strongly recommended the you inspect and clean the dryer exhaust vent hose. You should repeat this a couple of times a year to ensure it remains obstruction free.

The most frequent causes of dryer vent clogs comes from the following:

1. Ducting that runs in an upward direction in homes that have an attic exhaust. This is a stupid design that gravity will always win. When the dryer shuts offf, anything left in the vent will fall down the ducting to the base of the wall and accumulate. Over time, this forms a clog.

2. Ducting that runs under the home in a crawl space. If not correctly hung from the rafters, the ducting will develop sags causing choke points where lint can accumulate. Leaving it on the ground is not the answer, either. This gives opportunity for rodents to possibly chew through it. This will cause leaks which exhausts warm moist air under your home resulting in mold and mildew.

3. Using plastic dryer vent hose. This type of hose is not recommended because it kinks easily and can get crushed, causing an obstruction where lint can clog. Rodents can also chew through it easily. Pushing the dryer up against the wall and crushing the hose is a common cause. Use the semi-rigid metal type ducting that resists crushing, kinks and rodent infestation.

4. Rodents. Mice love lint. If given the access to it, they will build inside the dryer vent hose which provides a nice warm place to live with lots of bedding material. Make sure you exhaust vent on the exterior of your home is about 12 inches from the ground.

5. Exhaust vent screens. I know there are many types of exhaust vents on the market that you can purchase that have screens on them to prevent birds and rodents from entering them. The screen can actually become and obstruction, though. The smaller the opening, the more resistance the blower fan meets and lint will clog at the end of the exhaust. If you chose to use a protected exhaust vent, the ones with louvers work better. You will still need to periodically check the ensure it does not become clogged.

6. Excessively long vent hose. The rule of thumb when it comes to dryer vent ducting is: The SHORTER and STRAIGHTER the run, the BETTER. Excessively long dryer vent hoses will clog due to the fact that the blower fan is not able to push all the air and lint all the way to the exhaust.

7. Kinked, Excessively Bent, or Crushed vent hoses. If the vent has any choke points due to kinks, bends, or gets crushed behind the dryer, you will develop ponts where the exhaust vent will clog.

I know it may seem that I'm beating this point to death, but it is important to provide good air flow for your dryer. The number one cause of dryer failures and house fires comes from poorly maintained and poorly installed ventilation ducting.

Dryer stops after short time


I believe your exhaust duct with five 90 degree turns has weakened the limit switch in the exhaust pipe where the hot air leaves the dryer. Let me know if taking the hose loose will increase the dryers time. If not then we will need to replace the limit switch. Let me know as i will be able to help you further.
