Quick Answer
Okay, so here's the quick version. Nine times out of ten, your dryer is taking forever because it can't breathe. It's almost always a clogged vent. First, clean your lint screen—every single time. Then, check the vent hose behind the dryer for kinks. If that's not it, you've got a bigger clog in the vent line going outside. Cleaning that out will fix the problem for most people. If it's still not getting hot at all, you might have a bad heating element or fuse, which is a bit more involved.
Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
Clean the lint filter thoroughly. Wash it with soap and water if it has residue from dryer sheets.
Step 2
Pull the dryer out and inspect the flexible vent hose for any kinks or crushing that restrict airflow.
Step 3
Disconnect the vent hose from the back of the dryer and run a small, timed load. If drying improves, the clog is in the wall vent.
Step 4
Clean the entire vent system from the laundry room to the outside exit using a dryer vent cleaning kit.
Step 5
If there's still no heat, unplug the dryer and use a multimeter to test the thermal fuse and heating element for continuity.

When to Call a Professional Appliance
- If you've thoroughly cleaned the entire vent system and the dryer is still not drying properly.
- If the dryer produces no heat at all, indicating a definite part failure like a fuse or heating element.
- If you have a gas dryer and you suspect an issue with the gas line, igniter, or flame.
- If you smell a strong burning odor, which is an immediate fire hazard.
- If you're not comfortable taking the appliance apart or working with electrical components.
Prevention Tips
- Clean the lint trap after every single load, without exception.
- Have the entire dryer vent ductwork professionally cleaned at least once a year, or do it yourself with a kit.
- Replace flimsy foil or plastic vent hoses with rigid or semi-rigid metal ducting.
- Regularly check the outdoor vent hood to ensure the flap opens freely and isn't blocked by nests, leaves, or snow.
- Avoid overloading the dryer to ensure proper airflow around the clothes.
