Hey guys I'm needing to replace the fan motor in my duotherm and having a hard time finding a replacement. Seems they don't make that part number anymore and I really hate to get rid of the whole unit over just a blower motor. <br/>The unit is a: 600315.321<br/>part number is 991720671<br/>The motor is a:k55hxcrc-6598 <br/>part number is 3105417.004<br/>Any help would be greatly appreciated....
