Steps

1
Disconnect the dryer from the electrical outlet and move it away from the wall to access the rear and side panels.
Tip: Clear the area around the dryer to ensure you have plenty of room to work.
2
Remove the back panel screws using the Phillips #2 screwdriver to expose the heating assembly.
Tip: Keep screws organized in a small bowl to avoid losing them.
3
Locate the thermal fuse and test it for continuity using the multimeter.
Tip: If the multimeter shows no continuity (infinite resistance), the fuse is blown and must be replaced.
4
Inspect the heating element coils for any visible breaks or burnt-out sections.
Tip: Even a small break in the coil will prevent the dryer from producing heat.
5
Use the multimeter to test the heating element for electrical continuity.
Tip: A lack of continuity indicates a broken internal wire or burnt-out element.
6
Check for loose screws or broken wires connecting the heating element to the power source.
Tip: Tighten any loose terminal screws to ensure a secure electrical connection.
7
Replace the defective thermal fuse or heating element with new, compatible parts.
Tip: Ensure the new part matches the manufacturer's specifications exactly.
8
Reassemble the back panel and secure it with the original screws.
Tip: Do not overtighten the screws to avoid stripping the threads.
9
Plug the dryer back into the power outlet and run a short test cycle on high heat.
Tip: Stay with the machine for the first few minutes to ensure it is heating normally.

Pro Tips

  • Always verify that a broken wire or loose screw is not the cause before replacing expensive components.
  • Clean your dryer vent while the machine is disassembled to prevent future overheating and fuse failure.
