Omniflow reflow blowers going bad ?

Omniflow reflow blowers going bad ? | 11 September, 2007

We seem to have a lot of blowers going bad on our Omni 10 lately. We run PB free and/or elevated sn/pb profiles on a regular basis.

I am starting to suspect that the elevated zone temps are causing the blowers to fail.

Has anyone else had this problem ?

We have an Omni 7. We were having problems where blowers wouldn't start. Turned out to be the start capacitors and not the blowers. I replaced all of the caps and haven't had any issues since.

These blowers squeel then quit.

Usually the bearings lock up. I keep one spare blower on hand and change it out when I have one go bad, then take the bad one apart and change the bearings. The bearings are about $4.00 per set and are pretty common. Not too hard to find. I am using NTN bearings. Part#608ZZC3. It will save you a lot of money. Hope this helps.
