Hello I have has a bis nova since the beginning of fall and am experiencing blower issues that I cant seem to figure out. If I replace the motor can I get a uzy5 instead of the uzy6 as originally came with. If so can i fit two blowers under there? Idk if anyone here has done thos with the nova but after surfing the net I figured this is the best place to ask. Motor problem consists of cage stopping and motor humming. I took it apart cleaned it and it ran fine a could days then today it stopped until I turned it off waited 5 seconds themed it back on and its been running fine for about 5 hrs now. Looking for more permanent fI'd thougb since its a pain to actually get to the motor. Thanks for any help
