Hello!!
Well, the pics are blurry, but you get the idea. I have an about 15 year old portable evaporative cooler that has been doing it's job (with like every six month cleaning) great!! But now, because I think the blower motor is dirty. The system cooler fan speeds will now vary as it seems to sense the blower is slowing down, speeds it self up, then it's going to fast so it slows down, then repeats. When I rotate the assembly by hand, it seems resistant and 'bogged down'. Motors need lubrication, even those that are 'sealed' or something to protect moving parts, on SOME BLOWERS.
Well I disassembled the unit as far as the pics. I vacuumed everywhere out then wiped down with a damp rag, just cause. I spun the blower while I vacuumed, but it didn't seem to help; blower is still noticeably resistant. I don't want to disassemble it any more without asking some people that may have experience with this, THANKS!!!!!
