The Most Common Causes
These are the failure modes our technicians see most often on this symptom — listed in rough order of frequency. We don't publish step-by-step repair instructions for liability reasons, but the diagnostic process below identifies which one applies to your machine before any parts get swapped.
Clogged vent line
The single biggest cause of long dry times. Lint accumulates over years. Heat can't escape, moisture can't leave, and your clothes sit in a warm humid drum forever.
Crushed or kinked transition hose
The flex hose between the dryer and the wall vent gets crushed when the dryer is pushed back. Half the airflow is gone before the run even starts.
Weak heating element on its way out
An element with a partial break still glows but produces less heat than spec. Times go up gradually until it fails completely.
Failing thermostat or cycling thermostat
If the dryer thinks it's hotter than it is, it'll cycle the heat off too early. The drum is warm but never really hot enough to evaporate moisture quickly.
Overloaded drum
Worth mentioning. Stuffing the drum past capacity cuts air circulation in half. The fix is free — but if loads have been normal and times have grown, the parts side is what we're looking at.
Before You Call — What's Safe to Try
Some of this you can absolutely handle, and we'll tell you straight which parts. Other fixes are doable but carry real risk, and a few you should never touch. This is general guidance, not professional advice — always unplug the appliance (or shut off the gas/water) before you check anything, and if it feels beyond you, that's exactly what the $50 Quick Check is for.
✅ Safe to try yourself
- Clean the lint screen every load. A film of fabric softener can choke airflow even when the screen looks clean — wash it with soap and water.
- Clear the full vent run. Lint packed in the duct or a flap that will not open outside is the most common reason for long dry times.
- Do not overload. A packed drum cannot tumble air through the clothes. Smaller loads dry faster.
⚠️ Doable — but know the risk
- Partial heat failure. A weak element or a failing thermostat can heat just enough to seem "on" but dry slowly. Testing means opening the cabinet with the power off.
🛑 Call a pro — don't touch this
- Gas burner / igniter issues
- 240V wiring
- Control board
The Honest Answer
Almost always — and often the fix is mostly a vent cleaning, not a parts swap. Vent service plus a thermostat is typical $150–$250. Heating element replacement runs $200–$300. The honest answer: don't replace the dryer until someone has confirmed the venting is clear. We've seen brand-new dryers fail because the old vent was never inspected. Parts availability and labor complexity matter more than the age of the machine. A well-built ten-year-old appliance with an available part is often worth fixing twice. A newer unit with a discontinued board is the harder call. Our techs lay both options out side-by-side — repair cost vs. replacement cost — and let you decide. Try the replacement calculator for a quick framing, but every situation is different.
