Why Does My Dryer Stop Before the Cycle is Done?
A dryer that starts then stops partway through a cycle is one of the most frustrating appliance problems — especially when you pull out damp clothes thinking they're done. Here are the seven most common causes:
1. Clogged Lint Filter or Vent (Most Common)
This is the #1 cause of dryers cutting out mid-cycle. When the lint filter is full or the exhaust vent is blocked, hot air can't escape and the dryer overheats. The thermal fuse or thermostat then cuts power to protect the machine.
Fix: Clean the lint filter before every single load. Then inspect the full exhaust vent run from the dryer to the exterior — remove any blockages, kinks, or crushed ductwork. A clogged vent is also a serious fire hazard.
2. Overheating — Thermal Fuse Has Blown
Most dryers have a one-use thermal fuse that permanently blows if the dryer overheats. Once blown, the dryer either won't start or will start briefly then stop. Unlike a thermostat, a thermal fuse doesn't reset — it must be replaced.
Fix: A technician can test the thermal fuse with a multimeter and replace it. But crucially — fix the underlying overheating cause (usually a blocked vent) or the new fuse will blow again.
3. Faulty Door Switch
The door switch signals to the dryer that the door is closed and it's safe to run. If the door switch is faulty, the dryer may start then intermittently cut out as if the door has been opened.
Test: Press and release the door switch button manually (with the door open) — you should hear or feel a click. If it feels sticky, loose, or makes no click, it likely needs replacing.
4. Moisture Sensor Issues
Auto-dry cycles use moisture sensors (two metal bars inside the drum) to detect when clothes are dry and stop the cycle. If these sensors are coated with dryer sheet residue or fabric softener buildup, they can misread moisture levels and stop the cycle early.
Fix: Clean the moisture sensor bars with a cotton pad and rubbing alcohol. They're usually located just inside the drum near the lint filter.
5. Overloaded Drum
Overloading the dryer restricts airflow and causes the motor to work too hard, triggering thermal cutouts. Clothes also take much longer to dry and may come out damp.
Fix: Split large loads into two smaller ones. The drum should be no more than 3/4 full for efficient drying.
6. Drive Belt Broken or Slipping
The drive belt spins the drum. A worn or broken belt may cause the drum to start, then stop rotating mid-cycle while the motor continues running. Many dryers have a belt switch that shuts the machine off if the belt breaks.
Symptom: Motor runs but drum isn't turning, or dryer stops shortly after starting with a humming sound.
7. Control Board or Timer Fault
On older dryers, a faulty mechanical timer can cause erratic cycle behaviour. On newer electronic models, a failing control board can interrupt cycles unpredictably.
When to Call a Technician
If cleaning the lint filter and vent doesn't solve the stopping problem, the issue is likely a blown thermal fuse, faulty door switch, or belt/motor problem — all of which require a technician. AWS Domestic Appliance Repairs diagnoses and fixes dryer problems same-day across Atlanta.
