I've tried to be thorough and make sure this isn't a duplicate, but I've exhausted all suggestions I've found in other posts...

The drier started turning on the "Check Vent" light a week or two ago, on every run. Using the manual time cycle does not do this, and I've learned elsewhere this is because the manual cycles do not check the sensors.

Here's what I've done so far...

1. Checked hose from dryer to wall. It's only 9 months old, and was clean as a whistle.
2. Used a brush head, drill, and rods to clean the full vent from inside to out. Not much came out, seemed to be pretty clean.
3. Replaced the exterior hood.
4. Disassembled dryer and cleaned (shop vacc-ed) the general areas, lint filter area, duct from filter to blower, lower blower area (lots of crap here), exterior of heating element, motor.
5. Completely removed blower and verified free movement, and no buildup internally.
6. Verified drum, motor, and blower spin freely.

Air flow seems normal.

I don't have detailed info on which sensors matter to the check vent light, so I haven't checked any of them yet. I also forgot to inspect the door seal, so not 100% sure there, but I think it is fine.

I'm going to continue to use the dryer for now, regardless, but any other ideas?

FIXED - WED95HEDW0 Whirlpool Duet Dryer Check Vent Light

I have a Whirlpool Duet washer and dryer I purchased in March of 2015. The dryer (WED95HEDW0) check vent light illuminated recently after a few minutes of starting a drying cycle. I disconnected the vent line and ran several drying cycles venting into the house with no check vent light...

You still either have a blockage Look at post #13

I found an actual blockage in the vent. Go figure. I shoved a leaf blower in the vent and let her rip for about 60 seconds. Somehow the snake I used earlier must have just moved the blockage.

Check Vent Light Fixed

Hi Jake,

Thanks to you (and Pete for the original post) the check vent light no longer goes on. For the past few weeks, I had tried cleaning the vents, disassembled the dryer to clean out the vent, scrubbed the lint screen, etc., but that light kept coming on. I just saw your advice to clean those sensors with rubbing alcohol, and, voila! No more light. Thank you Jake!!

Look at my post #7--->I always advise my customers to try to clean the moisture sensor bars with rubbing alcohol and see if that makes a difference.

I forgot to include in my steps taken that I cleaned the moisture sensor bars. I didn’t have any alcohol handy, so I used nail polish remover.
I love tools, perhaps I should buy a scope. Business expense since it’s for my rental!

Also, you can pull the dryer out from the wall, then remove the vent exhaust hose from the back of the dryer, and run a dry cycle with no vent hose attached to the dryer and see if you still get that "Check Vent" light to come on.
