Dryer Taking Forever to Dry Clothes? Here Is Why

If a normal load now needs two or three cycles, your dryer is telling you something. In most homes we visit, the dryer is still producing heat. The real problem is that the moist air has nowhere to go.

A dryer taking too long to dry is one of the most common calls we get in Guelph, Kitchener and the surrounding area. Here is what we usually find.

Before checking anything, unplug the dryer. For a gas dryer, also turn off the gas supply valve before moving it. If you ever smell gas, leave the house and call your gas utility right away.

1. A Dirty Lint Screen

It sounds too simple, but a lint screen that is not cleared every load cuts airflow noticeably. Pull it out after every cycle.

Once a month, wash it with warm soapy water and a soft brush. Dryer sheets and fabric softener leave a film that blocks air even when the screen looks clean.

2. A Clogged or Crushed Dryer Vent

This is the big one. The dryer vent carries hot, wet air outside. When it fills with lint or gets squashed behind the machine, moisture stays in the drum and drying times climb.

Go outside while the dryer is running and hold your hand near the vent hood. You should feel a strong, warm flow of air. A weak puff means a blockage somewhere along the line.

Next, pull the dryer out and look at the duct behind it. Flimsy foil or plastic ducts kink and sag easily. A rigid or semi rigid metal duct with as few bends as possible is the better choice.

Check the exterior flap as well. Birds build nests in them over an Ontario summer, and in winter snow and ice can hold the flap shut. A clogged vent is also a fire risk, so clean the full run at least once a year.

3. Overloading the Drum

Clothes need room to tumble. A packed drum dries slowly and leaves wet pockets in the middle of the load. Aim to fill the drum about halfway to two thirds.

4. Clothes Coming Out of the Washer Too Wet

Sometimes the dryer is not the problem at all. If the washer is not spinning properly, clothes arrive soaking wet and take far longer to dry.

Wring out a towel after the final spin. If water streams out, the washer's spin cycle or drain needs attention.

5. A Dirty Moisture Sensor

Most newer dryers use two metal sensor bars inside the drum, usually near the lint screen, to decide when clothes are dry. Softener residue coats those bars, and the dryer can end the cycle while clothes are still damp.

Wipe the bars with a soft cloth and a little rubbing alcohol every month or two. If auto dry keeps leaving clothes damp but timed dry works well, the sensor is the likely culprit.

6. Worn Drum Seals

Felt seals at the front and back of the drum keep air moving through the lint path. When they wear out, the dryer pulls in room air instead and drying slows down.

Replacing seals means taking the cabinet apart, so it is a technician job.

7. A Heating Problem

If the dryer tumbles but the air inside feels cool, you are dealing with a heat issue rather than airflow. We cover that in our post on a dryer not heating.

Keep in mind the two are often linked. A blocked vent can overheat the dryer and blow its thermal fuse, which shuts the heat off completely. The vent has to be cleared before a new fuse goes in, or the new one will fail too.
