What's actually causing this
Dryers stop heating when the thermal fuse blows (a safety device triggered by overheating), the heating element fails, the gas supply is interrupted, or a clogged vent causes the unit to overheat and shut off.

Step-by-step fix
-
1
Clean the lint trap and vent hose
Remove and clean the lint screen. Then disconnect the vent hose from the back and run a vent cleaning brush through the full length of the duct to the exterior. A clogged vent is the most common cause of dryer overheating and thermal fuse failure.

2
Check the circuit breaker (electric dryers)
Electric dryers run on a 240V circuit with two breaker switches. If one trips, the drum tumbles but there's no heat. Reset both breakers — flip them fully off then back on.
-
3
Test the thermal fuse
Unplug the dryer. Access the back panel and locate the thermal fuse on the exhaust duct. Test with a multimeter set to continuity — no continuity means it's blown and needs replacing.
-
4
Replace the thermal fuse
The fuse is held by two screws and two wires. Take a photo before disconnecting. Replace with a matching fuse (check your model number). Don't bypass the fuse — it's a safety device.

5
Test the heating element (if fuse was fine)
The heating element is a coiled wire inside the back panel. Test each terminal with a multimeter for continuity. A break anywhere in the coil means it needs replacing.
Appliance technicians in Seattle typically charge $70–130/hr for service calls and repairs. Major appliance replacement costs $500–2,000+ per unit.
Standard U.S. sizes. Gas and electric heat common. Washer/dryer hookups standard. Venting is straightforward.
High humidity can promote mold growth in washing machines and dishwashers. Leave doors ajar between cycles and run cleaning cycles monthly.
DIY in Seattle: Seattle's moderate licensing and environmental focus create a fairly DIY-friendly environment for homeowners. Many people handle minor plumbing and electrical work. Moisture management, mold prevention, and basement waterproofing are common DIY focuses.
- You've replaced the thermal fuse twice in a short period — the root cause isn't fixed.
- The dryer makes a loud squealing or grinding noise.
- It's a gas dryer and you smell gas.
- The drum doesn't turn at all — likely a broken belt or motor.
