broken dryer moisture sensor?
 
I have another thread below where I asked about making a good connection between the dryer and the vent pipe. It isn't pretty, but it works. Used a lot of metal foil tape.

My problem is that a lot of moisture builds up on the inside of the dryer.
It takes 2 hours to dry a medium load of towels.

This dryer was bought brand new 18 months ago. It gets 2 loads of laundry a week.

A month ago I paid someone to "clean the dryer vent" thinking that it was the problem for the long dry time, but his camera showed that the vent pipe was clean.
The dryer vents straight up through the attic.

So, my question is, what now?

It is a broken moisture sensor?
Or something else?
The back of the dryer feels hot when it is on.

If I call a repair place they are going to automatically think clogged vent, but I don't think that is the problem.

sure sounds like a restricted vent to me. How long is the vent and what kind of termination is on the end. Hiring some one to run a camera through it to check it makes no sense at all, I think you need a repair man that is willing to take the vent apart and look .

I don't know exactly how long is the run.

I do know that it is vented vertically through the attic to the roof.
Whether there are bends while it goes through the attic I don't know. The dryer is on the 2nd floor.

Is a dryer repair person going to be able to go up on the roof to check the vent up there? Are they insured to do so?

The vent cleaning guy did not go up on the roof. He did put some vent cleaning brush on the end of his power drill and put it up the vent pipe.

Get up in your attic and untape one of the seams in the drier vent. turn on the drier and see if it blows into the attic. If it doesn't then you've isolated your clog. If it does, look up the other pipe and see if you can are day light. If you can't then your clog is probably at the roof. Either way you've isolated the location of your clog or eliminated a clog add a plausible option.

I was about to suggest the same thing.

One question....if you start the dryer and then open the door 10 min later, are the clothes hot?

I unhooked the dryer from the vent and turned it on briefly.
No clothes inside.
The exhaust out the back was forceful, and the air was hot.
When I quickly open the door, I can briefly see the drum spinning to a stop.
So, it is mostly a clog in the exhaust pipe which is what I was afraid of.
I will have to check that on Friday when I have the day off.

My builder told me to not go up in the attic, but I guess I will have to.
At the very least I can push up the cover and take a look to see what is going on with the exhaust pipe.

A co-worker suggested sticking the Shop-Vac hose up the exhaust pipe and see if I can get the clog, but my Shop-Vac is only 2 HP. Not sure it is strong enough.

What a pain. I hate dealing with issues that are hard to get to.

Along the lines of the shop vac, you can put a leaf blower into the duct where your dryer connects but the BEST thing will be to take the duct apart in the attic.

I know.

But got to try the easier approach first. :)

Do what?

Makes me wonder what he does not want you to see.....might want to take a camera with you.

It was the builder's supervisor's assistant who is Russian so his English wasn't too good. I think he was trying to say that it was not like the inside of the house. Not finished. "Rough".

This morning I finally took a look in the attic.

The dryer vent pipe goes straight up to the floor of the attic where there is an elbow which then allows the vent pipe to make about a 30 degree run to the side of the roof.

The attic run of the vent pipe is easily 25' given the elbow.
In addition, there are are the two bends in the flexible duct hose connecting the dryer to the vent pipe in the wall.
The vertical run of the vent pipe behind the dryer is approximately 7'.

Sheesh.

If I have a clog, I am thinking it is in that elbow in the attic. But it is all wrapped up in insulation and hard to get to.

It seems that a dryer booster fan would be good to have.

jfrotten 11-16-2012 08:59 AM

If you have a clog it is more than likely at the roof. There is usually a screen or a flap at the roof that can easily become clogged. The screen should have been removed on the build and the flap sometimes gets clogged with lint or a bees nest. Either way, the only way to check it and solve your problem is to separate a piece of the duct and look. Without doing that all you're doing is guessing.

Seems to me a dryer would have a hard time dealing with exhausting uphill then around a few L's. Did this just start since it has turned cold?

I am not sure what they are, but there are rules for how many bends in how many feet are allowable for dryer vents.

hOPE i REMEMBER TO CHECK BACK TO AAARRGG! I hate where the caps lock is on this thing!

I hope I remembe to check back and that you post what the problem is.

If I rememebr correctly, in the past, I would not get notices of responses from this forum. Maybe I need to check my settings. Iwould think I had done that, but.... maybe not.
