I have a whirlpool electric compact dryer model LDR3822PQ1. Lint is getting past the lint screen into the the exhaust vent behind the screen. I can see the lint building up but I cant get to it with my vacume hose due to the metal grate (looks like chicken wire) right behind the lint trap. How can I stop lint from escaping around the lint screen and into the vent?

Their is a connection that might be off and the only way to see it is to tilt it over

If your Whirlpool dryer has mysteriously stopped producing heat, a blown thermal fuse may be the cause of your problem. In Whirlpool dryers, thermal fuses are safety switches that are designed to disrupt the flow of electricity to your dryer's heating mechanisms once the dryer reaches a predetermined maximum temperature, usually somewhere around 180 degrees F. Thankfully, troubleshooting the thermal fuse in a Whirlpool dryer is easier than it sounds. Instructions:

Clean out the lint screen in your Whirlpool clothes dryer. Lint buildup can cause your dryer to overheat, triggering the thermal fuse to disrupt power to your dryer's heating mechanisms. Take the lint screen out of your Whirlpool dryer and wash it in warm water. Dry the screen thoroughly before replacing it.

Look behind the dryer to check its flexible exhaust hose for kinks or obstructions. Disconnect the exhaust hose from the back of your dryer and clean out any lint that has built up.

Go outside and check your Whirlpool dryer's exhaust vent for obstructions. Lint buildup, bird nests or other obstructions in the outside exhaust vent can trigger your dryer's thermal fuse.

Disconnect your dryer from its power source before attempting to access its thermal fuse.

Access the thermal fuse in your Whirlpool dryer by removing the back panel. Remove the screws that hold the back panel in place and it should easily come free.

Look between the dryer's blower housing and exhaust to locate its thermal fuse. The thermal fuse in a Whirlpool dryer looks like a white plastic strip that has two wires connected to it.

Bypass the thermal fuse in your Whirlpool dryer while you perform a quick diagnostic test. Use electrical tape to tape together the two wires connected to the thermal fuse. Reassemble your dryer and plug it back in. Set the dryer to a timed heated drying cycle and press "Start." If the dryer produces heat with its thermal fuse bypassed, it means the thermal fuse needs to be replaced.

Replace a blown thermal fuse in your Whirlpool dryer. Disconnect the power and remove the back panel. Remove the electrical tape that you used to perform the diagnostic test and disconnect the wires from the thermal fuse. Remove the screws that secure the thermal fuse to the dryer and discard the blown fuse. Attach the replacement thermal fuse by replacing and tightening the screws. Attach the wires to the new thermal fuse.

Check and make sure that your exhaust tube and outside vent are not clogged. If they are clean them out and you may have to buy and new lint screen that come with a seal whcih will solve your problem. Go to http://fisherpaykelparts.net/techhelp/fisher-paykel-top-load-dryers-us-models/ . This forum will further help you through your problem.

Check air flow out of unit and ensure you do have some foreign object stuck in the blower wheel. UNPLUG unit, and clear out exhaust tube from dryer. Have a professional clean house vent if you cannot see where the vent exits the house. It is common on Whirlpool, top of cabinet vent opening to have objects fall into the lint screen opening and restrict airflow.

there is a vent cleaning kit that can be baught at lowes or home depot and comes with attachments to get down inside the lint trap to be vaccumed out.
you can also lift the lid and remove the front panel and get to the trap area

squished vent hose behind dryer, then clogged vent, then dirty lint filter, then lint built up inside dryer because of vent issue, after fixing vent issue, remove lint from inside blower area filter area etc.

To dispell a common myth. 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. It is strongly recommended to have the exhaust vent hose checked and/or cleaned 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 becoe 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.

If you have any questions, pleae let me know. I hope you find this information helpful.

Here are a list of causes that may contribute to this lack of sufficient drying.


CAUSE
• Lint screen is clogged with lint.
• Restricted air movement.
Exhaust vent or outside
exhaust hood is clogged with
lint.
• Exhaust vent is crushed or
kinked.
• One fuse is blown or circuit
breaker is tripped. The dryer
will appear to operate, but you
will not get any heat.
• Cycle Control knob or temperature
selector is set on air dry.
• Load not contacting the sensor
strips and automatic cycle
ending early.
• Fabric softener sheets blocking
exhaust grill.
• Dryer located in room with
temperature below 45ºF (7ºC).
• Large amount of moisture in
the load.
• Cold rinse water used.
• Load too large and bulky to
dry quickly.


Here are the solutions to combat the issues.


SOLUTION
• Clean lint screen.
• Run dryer for 5-10 minutes. Hold hand under
outside exhaust hood to check air movement. If you
do not feel air moving, clean exhaust system of lint
or replace exhaust vent with heavy metal or flexible
metal vent.
• Replace with heavy metal or flexible metal vent

• Replace fuse or reset breaker.
• Select the right cycle and temperature for the types
of garments being dried.
• Level dryer.
• Use only one softener sheet per load and only use
it once.
• Move dryer to a location with temperatures above
45ºF (7ºC).
• Expect longer dry times with items that hold more
moisture (cottons).
• Expect longer dry times.
• Separate load to tumble freely.

This will help you fix this problem. i suspect an exhaust obstruction.

Friend,
huuum At your service!

Sometimes this can happen when the vent line is clogged.


1. Check if the lint filter is full and needs to be cleaned.
Try this first.If the vent line is kinked or blocked
2. Then check if the outside screen covering the exhaust vent if this is even half blocked
with lint there will be no heat! This screen is to keep small animals out!
Try checking this and if it is clogged or the spring loaded door is stuck closed.
Try to clean the lint out of the corners of the flap door,
and or remove the screen permanently!
NO ANIMALS LIKE TO GET BURNT,IT'S HOT IN THAT TUBE!
Take the vent line off the rear of the dryer and try if it works. If it does you know it's the vent line and not the dryer that's the problem the dryer.





You will be fine
Bless You huuum

Hello,
Here is a link to an exploded view and parts list for your dryer. http://www.pcappliancerepair.com/model-display.php
If you are certain that the filter is not compromised or damaged and is properly seated into the housing , you may have a problem with the housing itself whereby lint is getting into the blower thru a break in that housing.. I would examine that area for damage.. and make sure when you reinsert the filter, it is seated all the way down.. Hope this helps you... BTW: over time, it is not unusual for lint to build up in the duct since some of that lint is smaller than the filter media and will work its way thru.. If you are getting that degree of lint build up very quickly then you may have a problem as mentioned above..
Regards,
Rick
