I am a highly skilled and experienced home service professional. I recently completed a job replacing the idler pulley on a Kenmore dryer. The dryer was making a loud squealing noise, and I suspected that the idler pulley was worn out. To replace the idler pulley, I first removed the back panel of the dryer. Then, I accessed the idler pulley and removed the old pulley and bearing. I installed the new idler pulley and bearing, and then reinstalled the back panel of the dryer. After completing the job, the dryer was running smoothly and the squealing noise was gone. The customer was very happy with the results, and I was proud of my work. This job required a lot of skill and attention to detail, and I was able to complete it successfully. I am always happy to take on challenging jobs and provide my customers with the best possible service.
