⚠️ Professional Repair Required
This repair involves lethal hazards and should only be performed by a trained professional.
The information below explains what is likely wrong with your dryer so you can make an informed decision when speaking with a repair technician.
Disconnect power at the breaker, not just the plug. Dryers operate on 240V.
Clean the lint trap and exhaust vent completely before doing anything else. A clogged vent is the most common cause of dryer heating problems and is a fire hazard.
Common causes: clogged vent, blown thermal fuse, failed heating element, or faulty cycling thermostat.
Testing internal components requires opening the dryer cabinet and working near 240V wiring. If you are not comfortable with electrical testing, hire an appliance repair technician.
Order the part your technician will need
Knowing the likely failed part before you call saves time and money. Order it now so it is ready when your technician arrives.
Don't put this off.
A Dryer that's failing can cause water damage, electrical issues, or food spoilage — each costing 10x what the replacement part costs. The fix is straightforward. The part is cheap. The risk of waiting isn't.
🔍 Why This Happens
Root cause analysis for your dryer's not heating
The thermal fuse in your dryer degrades through repeated high-temperature cycles that stress the material. Each heating cycle causes thermal expansion and contraction — over time, the element fatigues and develops micro-fractures or the thermal safety device trips permanently. This is one of the most common failure modes for this appliance type, especially in units over 5 years old.

🛡️ Prevention Tips
How to prevent your dryer's not heating from happening again after this repair.
Clean the lint screen before every single load. A clogged lint screen reduces airflow, makes the dryer work harder, and is a fire hazard.
Have the dryer vent duct cleaned or inspected annually. Lint accumulates inside the duct over time, restricting airflow and overheating components.
Don't overload the dryer. Heavy loads strain the drive belt, drum rollers, and motor — leading to premature mechanical failure.
Avoid running the dryer on the hottest setting unless necessary. High heat accelerates thermal fuse degradation and stresses the heating element.
If you're replacing a thermal component, consider replacing related safety devices at the same time. The thermal fuse likely stressed surrounding parts.
