Dryers are supposed to make life easier, not longer. When we notice that one cycle no longer gets the job done, it’s easy to blame a heavy load or mixed fabrics. However, that’s rarely the full story. A dryer taking two full cycles to dry each load means something is off. Most of the time, the machine is trying to tell us it needs help. Understanding the cause now helps avoid bigger problems later. Let’s walk through the most common reasons and what we can do to fix them before calling for help.
Lint Buildup Slows Down Drying
Over time, lint can do more than fill the filter. It gathers inside vents, clogs airways, and stops the dryer from releasing hot, moist air. This warm air stays trapped inside, so clothes dry slowly. Therefore, every extra cycle is just the dryer trying to push through all that trapped heat.
Cleaning the lint trap after every cycle helps, but we also need to check the full vent line. That includes the pipe running behind the dryer and the vent flap outside the house. If we notice lint stuck to the wall or on the floor, there’s a good chance it’s backing up inside too. For safety and efficiency, it’s smart to clean out the full vent system once or twice a year. If the vent feels loose or crushed, that’s another reason airflow stops. For more details about safe maintenance, our dryer repair in Okotoks page offers a breakdown of the warning signs and fixes.
Heating Element Isn’t Working Properly
A dryer needs heat to do its job. When the heating element is weak or partially burnt out, the machine still runs, but it doesn’t get hot enough. Clothes spin and tumble, but they stay damp. In many cases, the dryer will feel warm to the touch but still not produce strong, steady heat.
To test this, we can run the dryer empty for a few minutes, then open it and feel inside. If the air is lukewarm or cold, it’s time to look deeper. A faulty thermostat, damaged heating coil, or worn thermal fuse might be the issue. It’s not easy to find or fix these parts without tools, but we can often catch the problem early by listening. If we hear clicking or smell something slightly burnt, that’s a red flag. When in doubt, getting support from a trusted appliance repair in Okotoks provider avoids bigger trouble down the road.
Sensor or Moisture Settings Are Off
Modern dryers use sensors to decide when to stop. These sensors measure humidity in the drum. If they get dirty or fail, they either end the cycle too soon or keep running forever. Both cases are frustrating. Either way, we end up running a second cycle to finish the job.
Sensor bars are usually metal strips inside the drum. Wiping them down with a cloth and vinegar helps keep them responsive. That said, if cleaning doesn’t work, the sensor might be faulty. In those cases, using a timed dry setting instead of auto dry is a good short-term fix. It helps us avoid wasting time wondering why the dryer stopped early. For long-term use though, we may need a technician to replace the sensor or recalibrate the machine.
The Load Is Too Large or Mixed Improperly
Every dryer has a weight and fabric limit. When we overfill it or mix too many different types of clothes, airflow struggles to reach every piece. Towels, for example, soak up heat while light shirts dry much faster. So even when half the load is dry, the other half stays damp and needs a second run.
The best approach is to sort by fabric weight. Drying jeans, towels, and sweaters in one batch, and shirts or undergarments in another, cuts down on drying time. Also, it’s better to fill the drum about two-thirds of the way. This gives clothes room to tumble and lets heat circulate evenly. If this doesn’t help, then the issue could be airflow, not load size. One of our technicians can review the situation during a dryer repair service visit and give specific advice.
Vent Ducts Are Damaged or Disconnected
The duct that carries hot air out of the dryer might be crushed behind the unit, disconnected at a joint, or damaged by heat. In each case, the hot air stays inside or leaks into the laundry room instead of venting outdoors. This not only slows drying but adds moisture back into the room.
Checking behind the dryer is a good place to start. If the hose looks pinched or loose, fixing it could solve the issue right away. In other cases, ducts inside the wall may have holes or sharp bends causing problems we can’t see. When that happens, we usually smell hot dust or notice condensation on nearby walls. It’s best not to ignore these signs. A full duct inspection ensures the entire system is safe, sealed, and doing its job.
Outdoor Vent Cap Is Blocked or Frozen
Even if the vent inside looks fine, the exterior cap may be stuck. Dirt, leaves, snow, or even a small nest can keep the flap from opening. If warm air can’t leave the system, it builds up and stops the dryer from finishing the cycle.
To check this, we can step outside and look at the vent cap while the dryer runs. The flap should open easily and let out a steady stream of air. If not, we might find lint packed behind it or ice sealing it shut. Clearing the cap only takes a few minutes, but it makes a big difference in airflow. During colder months, keeping the area around the vent clear helps prevent this issue from coming back.
Power Supply Is Fluctuating
Dryers need stable power to heat properly. When the voltage dips or wiring isn’t strong enough, the dryer might work, but not well. It spins, it lights up, but it doesn’t stay hot long enough to dry a full load. This happens more in older homes or when outlets are shared with other high-draw appliances.
Signs of electrical trouble include lights dimming when the dryer starts or a breaker that trips now and then. If we suspect a weak power supply, we should avoid running other large machines at the same time. Still, that’s only a workaround. A licensed electrician or experienced technician can test the power load and let us know if upgrades are needed.
The Dryer Needs a Deep Internal Cleaning
Even if the vent and lint trap look clean, there’s still a hidden side to every dryer. Inside the drum cavity and motor area, dust builds up over the years. This dust acts like insulation and holds heat in the wrong places, causing sensors to misread or heaters to shut off early.
A burning smell or strange noises during use can signal this kind of buildup. Over time, heat sensors might trigger safety shutdowns, which force us to start the dryer over. To fix this, some units need to be opened up completely. Our team at Freedom Appliances performs these types of deep cleanings as part of regular maintenance.

FAQs
Why does my dryer run but not heat up?
That usually points to a faulty heating element or thermal fuse. It may also be a power issue if the dryer is getting low voltage.
How often should I clean my dryer vent?
Once or twice a year works for most households. If you do many loads each week, clean it more often to avoid clogs.
Is it bad to run two drying cycles every time?
Yes. It wears out the dryer faster, increases energy bills, and may signal a larger problem with airflow or heat.
Can too many clothes stop a dryer from drying?
Absolutely. An overloaded drum limits air movement, so some clothes never get enough heat to dry completely.
Should I switch to timed drying instead of auto?
If the auto dry function isn’t working right, using a timed cycle helps maintain control until sensors can be cleaned or fixed.
