Ivan serviced my Whirlpool dryer and asked me to leave a review. He said he replaced all four rollers to fix a high‑pitch noise, but the noise returned and required a second visit. The issue still wasn’t resolved, so I had an independent technician inspect it. They found the rollers hadn’t been fully addressed and needed proper replacement and cleaning. After that, the dryer ran smoothly with no noise.Nothing personal — just consider who you call for service, and always get a second opinion before agreeing to any repair.
