Question about Dryers

Whirlpool duet dryer

Should we insulate our hot, moist vent duct in cold attic? straight up through the cold attic was our only venting solution, but we keep having problems with lint buildup, as the hot moist air condenses and the lint starts to "glob up". I think fiberglass insulation would help, but want to test my thinking against more experienced and knowledgeable minds!

-There is no way that it will not build up. No matter what material you use for. It will build up over time.
-Best thing to do I'll clean once every two year.

Good luck

    I have a computer reminder to clean the vent every other year! Lint build up is a leading cause of fires. I am wondering if I will have LESS lint build up if I insulate the vent in the attic space?

SOURCE: dryer whining noise, duct was part blocked, whining better, why whining?

Cleaning the lint trap often isn't enough to maintain proper dryer ventilation. No lint screen is perfect and some lint always gets past the intial screen. As you have discovered, rodents love lint as nesting material. It is common to find mice nests in places such as the blower fan assembly and along the dryer vent hose. I would recommend you inspect the vent about once per season. That is, four times per year. Most manufacturers recommend twice, per year, but I have found it better to check a little more frequently. The following link provides you with some good advice on proper dryer maintenance:

Pay particular attention to the section that discusses dryer ventilation. Something as simple as a clogged vent can cause serious problems with the heating circuits. Not to mention, it can create potential fire hazards. I would recommend you try running the dryer for one load with the vent hose removed. If the load takes less time to dry, I would inspect your dryer ventilation thoroughly from the point it exits the dryer, to the point where it exits your home. If you are not using the semi-rigid metal type ducting, or if the vent line has not been replaced in a while, I would recommend you do so. The ducting is sold in 10 foot segments, is fairly inexpensive and easy to install. The air at the back of the dryer should be forceful and warm (about 140 degrees F). If the air flow is weak, and not very warm, you still may have problem internal to the dryer. Here's another link you can view that discusses proper ventilation installation:

The rule of thumb when it comes to dryer ventilation is the SHORTER and STRAIGHTER the ventilation, the better. Every bend, sag, or rise creates resistance for the blower motor and can create potential choke points for lint to clog. Vent lines that run through an attic or crawl space are generally the worst for clogs. Also, make sure the exhaust outside is at least 12 inches off the ground to prevent rodents from entering.

To answer your question, if the dryer seems to be performing well and drying as it should, you probably have no problems at this point. I would recommend, however, that you inspect the dyer interior to make sure you don't have lint build up inside. Since you said you had cleared a clog recently, I suspect you may have some lint build up in the cabinet. This can cause a potential fire hazard. I would also recommend you lubricate the dryer drum supports (rollers) at the point where the roller meets the axle with a light weight machine oil. DO NOT get oil on the rubber rollers. These rollers can also cause noise if not lubricated periodically. I hope you find this information helpful. Let me know if you require additional assistance.

NOTE: Make sure you UNPLUG the dryer before servicing the interior cabinet. There are still live voltages present even with the dryer turned off.

SOURCE: Bosch condensation dryer model WTL5400vc. lint filter alarm

there is a reservoir in the base of the dryer which holds some condensing water prior to the pump pumping it to the holding tank at the top this has a float swith to tell the pump to come on and drain water to top tank this is probably stuck in the on position so the machine thinks it is always full of water and its waiting for you to empty it,you need to remove side panel and remove flost switch to clean, remove condenser and put youre hand in back of unit if its still very wet in there thats the problem should be bone dry at end of cycle.

hope this helps

SOURCE: Whirlpool Duet dryer not drying like it used to

If your duet isn't heating properly and you have taken care of the lint problem then you could have one of two problems. Either you have a bad heating element or you have a bad fuse or temperature sensor.
If your dryer is not heating at all then it is most likely the fuse or temp sensor. If it is heating and just not enough it is probably a bad heating element.
Both problems would require a repairman to come and fix normally, however if you believe it is the heating element that can usually be replaced by the homeowner without too much trouble. Just make sure to ask where it is located from whatever place you but the new element from.

The half of my house where the furnace is is hot. So there is hot air coming from the vents. (some of them). Half of the kitchen living room bathroom and 3 bedrooms and the hallway are blowing cold air.

where is the duct work located? In an attic, crawlspace? It sounds as if part of the system is disconnected. Are the outlets at the floor or in the ceiling? Is the duct work insulated? Can you take actual air temperatures at the outlets?

I am looking for a umbrella cap to cover my 15 inch attic exhaust fan

Many people just use large black trash bags secured with duct tape or bungi cords. Black bags won't deteriorate as fast as the white ones with the UV rays of the sun and should last one full winter.

If you're concerned about the neighbors complaining about the lack of asthetics....I can't help you.

I never cover attic vents nor recommend them to be covered, because a properly vented attic all year long ensures moisture removal from the attic area and from the insulation. Also if you have shingled roofing, each nail point extending through the sheeting will condense moisture and drip into the insulation in a non vented attic space. This happens many times each winter when the air temp and the moisture content collide on the dew point scale. It does NOT happen daily.

The nails conduct the warmth to the outside, cool down and attract the moisture from the non vented air on their exposed length and slide down to the tip dripping into the insulation. Moisture detracts from the insulations ability to do its job, and that's to insulate the living space from abnormally cold or hot temperatures.

How hot is the Vent temp of my new Duet?

It's not the temperature of the air that is the problem. The air is seldom over 160 Deg F. If you have a vent fire the piping needs to last long enough without melting to starve the fire of oxygen in the hopes of extinguishing. Rigid aluminum piping is best suited for this, Rigid flexible is next. The tin foil and white plastic offer little resistance to melting if a fire should begin. The melting would allow the fire to replenish oxygen and support the burning process. The main caution here is to keep your dryer and vent least annually.

If the duct inside your wall is rigid metal all the way from the dryer to the house exit you need to do nothing to it . Replace the vent between the dryer and the wall with rigid metal 4" piping or hard flexible aluminum piping. If the duct inside your wall is either of the least effective types you need a new run of vent for the dryer to avoid a fire.

You can't use white plastic or flimsy flexible aluminum that feels like aluminum foil when you touch it.

My whirlpool duet dryer is only 4 years old and it does not dry the clothes completely, even when it is on Heavy Duty. Only way it dries the clothes is if I run it through 2 cycles.

Check to see that the lint filter and exhaust duct are clear all the way to the outlet. If the moist hot air is not being exhausted the clothes will not dry. If the vent path is clear and you are using auto-dry the sensor may be at fault.

Why does my apartment fill up with moist air and fumes whenever I use the electric dryer on my GE SpaceSaver stacked washer/dryer combination?

You have a 4 inch duct hooked to the back of the dryer. The hot air, moist air etc. go through it to wherever it is vented to. Outside, attic or inside your apt. if it has come loose.

Dryer venting

Yes you can but make sure it is secured well. Remember, the vent will be putting moist hot air in the attic if it is not secured.
