Dryer takes two cycles to dry? It's the vent or the element. Here's how to tell.
A dryer that still runs but takes two cycles to dry a normal load has one of two problems, and they cost very different amounts to fix. One of them you can check yourself in ten minutes.
The ten-minute vent check
Run the dryer on high heat with a load in it and go outside to the vent flap. You should feel a strong, warm stream of air pushing the flap fully open. If the flap barely moves, the air is weak, or the air is warm but damp, the vent is restricted. That is the most common cause of long dry times in the Upstate, and it is also the most common cause of dryer fires.
Lint builds up in three places:
- The lint screen housing. Pull the screen, then shine a light down the slot. A vacuum crevice tool pulls out what the screen missed.
- The flex hose behind the dryer. Foil or plastic flex hose crushes, kinks, and traps lint. If yours is plastic, replace it; code in most places calls for rigid or semi-rigid metal.
- The run through the wall or crawlspace. Long runs with elbows collect lint you cannot see. Vent cleaning is a service most appliance techs and some HVAC companies offer, and it is cheaper than a repair.
If the vent is clear and the dryer dries normally after cleaning, you are done. No parts, no service call.
When it’s the heating element
If the vent test shows strong airflow but the air is only lukewarm, or the dryer runs with no heat at all, the problem is inside the machine:
- Electric dryers: a heating element that has partially failed, a cycling thermostat, or a high-limit thermostat that is tripping. A fully open element means no heat at all; a partially shorted one means weak heat.
- Gas dryers: a weak igniter, a failing flame sensor, or gas valve coils that open at first and then quit after the dryer warms up. The classic symptom is heat for the first few minutes, then cold.
These are a service call. A technician tests the element and thermostats with a meter, which takes minutes, and most carry the common parts on the truck. The parts themselves are inexpensive. What you are paying for is the diagnosis and the labor.
One more cause people miss
A blown thermal fuse shuts off heat entirely on most electric dryers. It blows for a reason, almost always a restricted vent that let the dryer overheat. Replacing the fuse without clearing the vent just blows the next one. Any tech worth hiring will check airflow before replacing it.
Repair or replace?
A vent cleaning is always worth it. An element or thermostat repair is worth it on any dryer under about ten years old. If the dryer is older than that and the drum bearings or motor are also noisy, get the repair estimate and the price of a new unit side by side before deciding.
If you are in Anderson, Pendleton, Clemson, or anywhere in the Upstate, call and we will connect you with a local technician who can check the vent and the element on one visit.
