I have searched through past posts and I too have an issue with the convection blower motor of my 5660 pellet stove. I bought a 3000 rpm universal motor using the original fan assembly. Since then I upgraded to the 250 degree high limit switch. I cannot run the heat setting above 4 without it tripping off the high limit. From the research on here others had upgraded to a snorkel and higher cfm blower fan. Can anyone help provide part numbers on where I can upgrade my pellet stove or suggestions? Thank you
