Roberta R Santa Fe , NM October 20, 2018 Dryer did not heat up The repairman explained that I needed to clean the dryer filter with white vinegar once a month. He then reset the shut off control at the back or the dryer and all was fixed. Josh, the repairman was efficient and knowledgeable. I finished scrubbing the lint filter and was back doing my laundry. I ordered an extra filter. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
