Dryer Repair Takeaway

Here lists the entire procedure of the dryer repair. The main issue is that my electric dryer started to vibrate and make loud noises when tumbling.

The repairer came and fixed the issue fairly quickly. But the overall experience was not good as the repairer was obviously not proficient and was not even concentrating on the job. I even needed to remind the repairer to reconnect all the wires and to screw back all the nails. Facepalm!

So, all the tools needed for the repair are:
An electric screwdriver - for screwing and unscrewing
A headlamp - for overall checking inside the dryer
A wood block - for raising the bottom of the dryer
A blanket - for protecting the disassembled components

Here are the steps:
0. Turn off the circuit breaker

  1. Unscrew two screws at the back
  2. Take off the top cover
  3. Unscrew two screws at the top
  4. Use the wood block to raise the front of the bottom
  5. Unscrew two screws at the bottom of the dryer
  6. Unscrew two screws aside from the round door
  7. Loosen the front board
  8. Disconnect all wires to the front board
  9. Take off the front board
  10. Disconnect other wires from the metal cover
  11. Take off two on the left, two on the right, two on the up right corner, and one on the bottom right corner - in total seven screws
  12. Take off the metal cover
  13. Check the blower
  14. Unscrew four screws around the blower
  15. Take off the blower cover
  16. Clean up the blower
  17. [optional] mark the top of the tumbler
  18. [optional] loosen the belt
  19. [optional] take off the tumbler

These are the steps to address my dryer’s issue. The root cause is the lint built up inside the blower. It is straightforward to open up the dryer and clean it out. The design of the dryer, or specifically, the shape of the blower was not ideal. It causes the lint not to be blown out of the machine, but stuck in between the blades of the blower.

With the above procedure written down, hopefully, I will be able to address this issue by myself next time and save the recurrent $300+ in the future.

Today I did a very successful dryer maintenance following the above procedures. Next time, I could create a follow-up post with some pictures.
