Just so you know, The Return duct ( the large vent toward the middle of the home, and sometimes there is more than one
), is where all the dust travels to.
The filter at this point needs to be changed monthly based on it ability to grab particles from that air coming into it. A very tight weave filter will trap more dust but it will also choke off the air to the system too. Usually once a month replace the filter, some go a little longer. Dont get the electrostatic type, waste of money.
One main thing that hampers a HVAC system is not enough air flow. If all of your interior doors are closed air does not return to the inlet very well starveing the sytem for air. If the filter is clogged not enough air flow. This duct area is where it could be cleaned if it really needs it. They make long poles or a flexible shaft with a stiff bristle on the end that will sweep the dust but then you would need to vacume that dust. Tough to do yourself, expensive to have others do it and Again it really doesnt need to be cleaned. Good Luck

The complete duct system is actually a bunch of hoses behind those circular vents. Cleaning the vents is the easy part. Just unscrew them and wash them in the sink. The hoses back to the air source is a more difficult matter. It is also rather messy! It can be done with steam or compressed air but unless you are prepared for a difficult and messy job, I do not recommend you do it yourself. However, you could use a ladder and long handled bristle brush to, at least get some of the hose. Keep a vacuum cleaner handy, preferably a commercial type vac.

Samsung DV448ae electric dryer. Sensor mode not working replaced the moisture sensor with not change. What could it be? Dryer is heating.

I may be misinterpreting your complaint, but I think your stating that the dryer doesn't dry properly. If so, the first thing I would check is to see if the exhaust duct is clogged with lint (they need to be cleaned out once a year or the ability of the dryer to dry clothes properly diminishes to zero).

What I do is, I disconnect the duct at the back of the dryer and connect a shop vac to the duct. (The kit comes with a shop vac hose-to-duct adaptor). Then I go outside, and using an cordless drill, attach a special duct cleaning brush to the drill (the kit comes with several extension wands to increase its length) and run the brush through the outside cover and down into the duct. The drill spins the brush, completely cleaning the interior of the duct. You can buy the brush at any home center, I bought mine at Menards.

Example: Amazon com Deflecto Dryer Duct Cleaning Kit Extends Up To 12 Home...

After I'm done, I'll also use the extension pipe on the shop vac and push it up into the dryer itself to clean out that part of the exhaust.

If you neglect to clean the duct, the dryer will eventually take forever to dry clothes and they will still come out damp.

Clean your air ducts and filter yourself

Cleaning your air ducts and replacing the filters can be small step that you can take to ensure that the air you are breathing is clean and to cut down on the electricity costs. While cleaning them yourself will not in any way come close to as thorough a clean as a professional cleaning. Taking an afternoon to clean your air ducts will make at least a small impact.

You will need a few tools to clean the air ducts that you probably have around the house, and if the filter is really dirty you will want to go to a home store and pick up a new one. You are going to need a vacuum, screwdriver, paper towels and a brush with stiff bristles.

Going room by room open the registers and and other air duct covers. With them open you should be able to reach a few feet into the ducts. Using the vacuum, vacuum up the dust and gunk in the ducts and if there is stuff that needs help getting out you can use the brush to loosen the stuck stuff. When the duct that you are working on is finished, close it up and move on to the next one.

You can continue this procedure for every register in the house and when you are finished it is time to get to the filter. Turn off the air conditioner locate the register in your house that covers the filter and get yourself a damp paper towel. Using the damp paper towel wipe the register clean if its dusty, and slowly open the register. If its on the ceiling you want to be careful that the filter doesn't fall on you. When its open remove the filter check the size and direction that the filter is sitting at (you need this for replacing it). Taking the new filter hold it with the air flow arrow facing the same direction as the old one. Close up the register and you should be good to go.

This method should help to reduce the dust particles in the air and will make your air conditioner a little more effecient. You should get a professional cleaning at least once a year to keep your air clean.

Duct Cleaning Can Be a Messy Job Or it Can Be Made Very Simple

There are many companies that advertise <b>air duct cleaning</b> as a way to make the air in your home cleaner and healthier. While that is a good thing, there is a better way to improve the air quality of your home. With the installation of a <b>UV light based air cleaner</b> your can keep the ducts of your home clean and free of the many bad things that like to grow in your<b> air ducts.</b><br /> Many people today are becoming concerned about the air ducts in their home. These are the passages that the air flows through to heat or cool their homes. They can become a breeding ground for numerous <b>molds, bacteria, and virus.</b> With the addition of a very simple appliance you can eliminate much of the danger that could come from your ductwork.<br /> <b>Ultraviolet Light</b> has been used for years to help to kill bad bacteria and <b>sanitize equipment</b>. <b>Water treatment facilities</b> use UV to treat the water before it is released into streams. In homes with wells that are contaminated, water can be treated by passing by a UV light. This type of light is very effective at killing micro-organisms quickly and efficiently. Some of these systems are even effective at getting rid of hard to kill things such as <b>SARS </b>and the <b>Swine Flu virus</b>.<br /> Now it is very easy to install an <b>Ultraviolet Light in your air ducts</b> to kill the many bad bugs that like to live in there. It is a simple as cutting a hole in your ductwork, mounting the unit to the side of the duct and plugging it in to an ordinary outlet.<br /> While a <b>physical cleaning or your air ducts may be a good idea</b> it can be very expensive, dirty, and time consuming. Also to do this means that the ducts must be cut into in many places and sealing them up again permanently is a problem. With this type of unit your ducts will self clean over time. I have seen many ducts that slowly clean them selves after the installation of a UV unit. It will not dissolve big hard items in your duct but it does tend to dissolve small dust particles and make your duct look cleaner.<br /> The main result of installing a UV unit in your <b>HVAC system</b> is that you will be breathing air that is free of the bad stuff that can cause health problems. Even if you choose to have your duct vacuumed and cleaned also consider the installation of a UV system to keep your ducts clean and sanitized.<br /> <b>Clean sanitary ductwork will give you and your family the healthiest, freshest air to breath possible</b>.

Frigidaire electric Dryer 1317150009709 malfunction

I would first clean out the lint trap. Then pull the unit out and clean out the duct work venting to the outside of your home. If there are kinks in this duct work, or too many curves, bends, turns, etc, then the unit is working way too hard to dry. This can cause the unit to overheat and burn out.

Sounds like you need to have the duct work cleaned by a professional.

Is your duct work in the concrete floor? If so check for water in the duct work. You can go to one of your supply grilles in the floor, take the grille up and look into the ductwork. If you have water, you need to find out if you have a plumbing leak or if it is just runoff from a hard rain. Nevertheless, it needs to be fixed.

Is your duct work in the ceiling? If so, and you still have mold, just have a professional duct cleaning company clean your duct work and it should solve your problem.

One other thing, make sure the condensate drain from your heater is not stopped up and dripping water into the duct work if the duct work is in the floor.

When to Buy a New Dryer or Fix Old One?

If your old clothes dryer is not working well, how do you tell if it's time to replace it?Here are some things to check before you set it on the curb with a"FREE" sign.
If it still turns on, runs a proper cycle, doesn't make a lot of squeaks and groans, and your clothes are at least attempting to dry, then check the following before you decide to replace.

1. Check and empty your lint trap before each load. If airflow is restricted, your dryer will need longer to get the job done. A clean lint trapwill allow for maximum intake air to the dryer blower.
2. Check the exhaust duct work for lint buildup. If the 4" duct work that carries your warm, moist, lint-laden air to the exterior of your home is blocked with years of lint and moisture, chances are pretty good your dryer is taking longer than it should to get your clothes dry.

  • Disconnect the dryer power cord (and gas line if a gas unit), slide the dryer forward far enough to access the 4" duct work clamp at the back of the dryer. Disconnect the duct work at the dryer and separate to inspect both in the dryer exhaust duct and the duct work as well.
  • Remove all built up lint. You may need to access under the floor, or in the crawlspace, or basement to get at all the areas that lint may be built up. Remember that when there's an elbow chances are pretty good there's lint in there, so take the time to separate the duct work where needed to give it a thorough clean out.
  • Long straight sections of duct work can be easily cleaned by using a Webster-style pole brush.
  • Clean the exhaust duct of the dryer but be careful not to damage anything inside your dryer
  • Reconnect and turn the dryer on air fluff to blow the rest out.
3. Remove lint build up from inside the machine
  • Turn power off again
  • Remove the front cover of your dryer
  • Remove the front drum support/air duct from the front of the dryer
  • Carefully vacuum the lint out of the dryer with soft brush attachment on your vac. Be careful not to damage any igniter or electrical items.
  • Clean the inside of the lint trap duct of sediment/ buildup
4. While you've got it open replace the drive belt and check the pulleys.

If this improves your dryer, hang onto it for a while longer! Most times dryers just need a good cleaning and the exhaust duct cleaned. If you're not satisfied with the results, take it to the curb and recycle it to another family.

The dryer heats up but does not dry the clothes completely.

Hi and welcome to FixYa, I am Kelly.
If your dryer cabinet is feeling very wam to the touch and your clothes are not drying properly it is always caused by poor air flow problems.
Here are steps you should to attempt to get it working normally again:
1. Pull out the lint filter
a. Inspect the cavity where the lint filter was (use a flashlight). Make sure there is not lint build-up under the lint filter. Use a folded wire coat hanger and a vacuum with a crevice tool to remove any lin in this area.
b. Wash the lint filter with vinegar and water then soap and water. Fabric sheet particulate builds up on the lint filter. It will appear clean but can still be almost completely blocked.
2. Remove / dis-connect the vent duct from the back of the dryer.
a. Turn on the dryer briefly and check air-flow. The air-flow should push a relaxed hand gently away from the immediate area of the vent duct connection. If you do not have good air-flow here you must inspect the internal ducting of the dryer for restrictions. Use the folded wire hanger and a vacuum to remove any debris from the internal duct vent ducting.
3. Inspect the ducting from the rear of the dryer all the way through and OUTSIDE the home. The vent flapper outside the home is most often one of the primary reasons for poor airflow. Clear the lint from both sides of the metal flapper outside the home.
4. Lastly if after doing all of the above you still have poor air-flow the most likely failure is the blower wheel attached to the motor shaft. Either there is a problem with the fan blades or the center hub has failed allowing the blower wheel to spin on the end of the motor shaft.

A final comment... when you think you have the internal dryer ducting clean.. start over cleaning again for a 2nd cleaning. I cannot tell you how many times I have performed in-home service and the customer said they had done all of the above yet when I clean the same ducting I can fill a 5 gal SHOP-VAC 50% full with the lint they did not remove.

Thanks for choosing FixYa,

It may be as simple as dryer duct needs cleaning. I provide that service to several of my commercial customers in group homes. When the duct work is partially closed from build up it reduces dryer efficentcy. Also if you have flex vinyl duct work replece it, its a fire waiting to happen.

Don't blow enough air

Here are a few things that would cause low amount of air to come out of the registers in home:
1. Something is blocking return air, like couch in from of return air register.
2. Dirty air filter. Clean or Replace!
3. Icing. Check large pipe on outside unit. If it has ice on it shut off sustem and call a qualified technician.
4. Fan speed may be wrong on blower. Put on HIGH.
5. Duct work may be apart. Check duct work and correct if needed. Note: If you have asbestos duct work do not repair. Call a qualified repair company.
I hope I have helped.
