Dryer Not Heating or Taking Too Long? Vent Checks That Save Money

If a dryer needs two or three cycles to dry a load, resist the urge to replace it. In most cases it is a blocked vent, a full lint trap or a worn part that costs little to fix.

Step 1: the lint filter

Clean it after every load. Wash it with warm water and a soft brush once in a while to remove the invisible film left by fabric softener sheets, which blocks the mesh.

Step 2: the vent hose and outside vent

1. Pull the dryer out and disconnect the vent hose from the back.
2. Check it for kinks, crushed sections or heavy lint.
3. Clear it with a vent brush kit, and check that the outside flap opens freely when the dryer runs.

Step 3: heat or no heat?

• Runs but is cold: on electric dryers, a blown thermal fuse or failed heating element is possible. On gas dryers, an igniter or gas supply issue is likely.
• Gets very hot then shuts off: usually restricted airflow tripping the thermostat.

Fuses and elements can be replaced cheaply by a confident DIYer with the power switched off at the breaker, but gas dryers should always be left to a professional.

Step 4: the load and the settings

Overloaded drums, wet-heavy items like jeans and towels together, or a wrong sensor setting add time. Try smaller loads and the right program for the fabric.

Yes. They are a common cause of dryer fires, so clean them regularly and use metal ducting.

My dryer runs but is cold. What now?

On an electric dryer a blown thermal fuse or failed element is possible. Gas dryers should be checked by a professional.
