Having a dryer at home is very convenient. Typically, it only takes me anywhere from 30 to 45 minutes to dry a regular load of clothes, but if I don’t clean the unit regularly, it might take longer than that.
This decline in efficiency could be accompanied by a check vent error, which can pose safety hazards if left unchecked. Although it sounds quite intimidating, it’s really easy to resolve.
We’ll show you how to fix a dryer check vent error like a pro. With a few tools and our easy-to-follow instructions, you can get your dryer back up and running in no time.
What is a dryer check vent error?
A check vent error appears when a dryer detects restricted airflow in the system, which reduces its efficiency. An obstructed lint screen, a bent vent hose, or a clogged exhaust vent are likely causes.
Luckily, a dryer check vent error is something you can resolve without professional services. Here are a few ways to troubleshoot the problem.
- Reset the dryer.
Power interruptions may cause your system to malfunction temporarily, prompting all sorts of errors. Just disconnect your dryer from its power source for a few minutes to clear any possible glitches.
- Confirm that the lint screen is installed properly.
A loose or missing lint screen may cause the dryer to overheat, so make sure to install it properly after cleaning. Just pull the screen out of the dryer and reinstall it to resolve the error.
- Inspect the lint screen for damage, and replace it if needed.
Check if the lint screen is torn. If there is damage to the lint screen, it can no longer effectively trap lint from your clothes and may cause a blockage in your exhaust vent system.
Get a replacement for your lint screen. Don’t run a load until you’ve replaced the broken part.
If the error still recurs, keep reading our guide. We’ll delve into other potential causes and help you determine what you might be dealing with.
Causes and Solutions
Let’s take a closer look at a few potential causes of a check vent error on a dryer. We provide step-by-step instructions to help you resolve each one like a pro.

Clogged Lint Screen
The lint screen is a mesh-like filter that traps any loose fibers and lint during the drying process. It collects all the gunk that can clog the vent system and restrict airflow.
You must clean the filter after every load to prevent potential problems. If there’s too much lint build-up on the screen, your clothes will take a longer time to dry and you’ll likely see the check vent error appear.
It’s important to clean the screen as the lint build-up is flammable, which can potentially cause a house fire due to the heat from the dryer.
What you’ll need:
- Hot water
- Liquid detergent
- Nylon brush (or an old toothbrush)
- Small container
- Long-handled wire vent brush
- Clean towels
- Vacuum

Quick Note:
Never run a dryer if your lint screen is damaged or missing. It can overheat, which can ruin your clothes and your machine.
Kinked or Crushed Dryer Vent Hose

One of the most common causes of a check vent error is a kinked or crushed dryer vent hose. Connecting the dryer to the outside vent, the hose helps expel hot air, lint, and moisture during the drying cycle.
Rigid metal ducts are more durable than plastic and foil tubing. They won’t easily get crushed or kinked when your dryer is pushed back onto the wall, which can cause venting issues and prompt a check vent error.
More importantly, metal vent kits are the safest option as plastic and foil tubing can easily catch fire from the hot lint that accumulates in the dryer.
What you’ll need:
- Scissors
- Pliers
- PVC pipe
- Rigid/flexible venting material
Solution: To straighten out kinks in your dryer vent hose, follow these steps:
- Step 1: Disconnect your dryer from its power source.
- Step 2: Pull the dryer about a foot away from the wall.
- Step 3: Remove the tape or clamps on the vent hose that connects the dryer to the vent system.
- Step 4: Set your vent hose on a flat surface. Get a PVC pipe and slip it about 2 inches into the hose.
- Step 5: Gently roll the vent hose with the PVC pipe inside to smoothen out the edges.
- Step 6: Cut three slots on the tubing to widen the opening.
- Step 7: Use pliers to make hook-like protrusions on the dryer vent.
- Step 8: Install the hose over the vent. Then, press down around the opening area to keep it in place.
- Step 9: Tighten the clamp to secure the hose.
- Step 10: Reconnect the dryer to its power source to verify that the check vent error has cleared.
Quick Note:
Never use plastic or foil vent kits for your dryer because they can be fire hazards. Instead, invest in rigid metal ducts made of galvanized steel or semi-rigid alternatives.
Clogged Dryer Vent
After cleaning the lint filter and the dryer vent hose, you can look for possible obstructions in your dryer’s vent area. This is where you connect the hose to the dryer.
Lint can build up here as well, restricting airflow and forcing your dryer to use more energy to push the air out of the system. You should inspect and clean this area once or twice every 6 months, depending on your usage.
What you’ll need:
- Vacuum
- Long-handled brush
Solution: To clean the dryer vent, follow these steps:
- Step 1: Disconnect the dryer from its power source.
- Step 2: Pull the dryer about a foot away from the wall.

Blocked Outdoor Exhaust Hood
If you’re done removing obstructions in the dryer and straightening any kinks on the hose, and you’re still seeing the check vent error, it’s time to clean the outdoor dryer vent.
Located in your home’s exterior wall, this exhaust hood is where hot air, lint, and moisture are expelled from the dryer. Like the dryer vent, you must inspect and clean this at least once or twice every six months to remove dirt build-up.
Depending on the type of exhaust hood you’ve installed, birds and other critters can crawl inside and build a nest. This can create further venting issues, reduced efficiency, increased energy usage, and potential fire hazards.
What you’ll need:
- Hot water
- Clean cloth
- Electrical tape
- Dishwashing liquid
- Dryer vent cleaning rods
- Long-handled wire brush
Solution: First, inspect the vent system’s airflow for possible blockages. If it’s obstructed, proceed to clean it.
- Step 1: Turn on the dryer. Set it on Air Dry for 5 to 10 minutes.
- Step 2: Press Start.
- Step 3: Place your hand on the exhaust hood to check the airflow.
If the air feels similar to a hair dryer on high speed, your vent system has no obstructions. However, if it isn’t as strong, dirt is most likely building up inside and restricting airflow.
To remove the obstructions, follow these steps:
- Step 1: Disconnect your dryer from its power source.
- Step 2: Remove any visible lint on the outside exhaust hood using your hands or a long-handled brush.
- Step 3: Remove the louvers of the exhaust hood. If you have an angled or a boxed type hood, skip this step.
- Step 4: Mix hot water and dishwashing liquid in a small container. Dip a clean cloth in this cleaning solution.
- Step 5: Wipe the exhaust hood clean using the cloth.
- Step 6: Assemble your long-handled wire vent brush by attaching the adapter to the drill and tightening it. Add the flexible rods, one at a time, until you reach your preferred length.
- Step 7: Tape the rods at the seams.
- Step 8: Carefully slide the brush into the ductwork.
- Step 9: Press the drill to rotate. Then, pull out the brush and remove all the lint.
- Step 10: Slip the brush into the ductwork again and repeat until it comes out clean.
- Step 11: Reinstall the louvers.
- Step 12: Turn on your dryer and confirm if the check vent error has cleared.
