Mr Glenn Turley, I purchased one of your stoves from Lowe’s. It was shipped. By the time I got it installed, it was over the 30 day return policy. I called tech support. I explained to them that during the burn phase and when the fan kicked, it made a rattling noise. Tech support sent out a new motor and said the fan may have been damaged during shipping. Being a new stove , I wanted a certified Comfort Built technician to replace the fan and motor. I went round and round with Jonathan and Todd via phone calls and texts. No good. Got to the point where they didn’t even return my texts. I work for NYSDOCCS and don’t get a lot of time. So, I took the day off eventually, fixed it myself. There is a design flaw that causes your noise…not a replacement part. Thanks John and Todd for nothing.! Clowns. I fixed the stove with a modification. I will not be buying another Comfort Built Stove and will spread the advice to every CO I know. Quality service starts with customer service. You just don’t blow off customers and tell them to do it themselves and they’ll extend parts warranty for a year.
