Hello all My Breckwell 2700 convection blower is squealing a bit for the first 10 minutes or so after the fan turns on during the startup process. After about 10 minutes, it hums along just fine. Since my stove is installed in a corner, and getting behind it is impossible without disconnecting the pipe, I was wondering if it's possible to remove that blower from the side panel? Maybe greasing the bearings will stop this initial squeal? Thanks in advance for your help!
