MaxxAir ceiling vent repair

The gear housing on one of our ceiling vents cracked. We had a mobile RV repair person evaluate it during an on-site repair and have ordered the part. It looks to be a simple replacement. However, I noticed some oil around the corner of the vent trim inside the camper as well as some on the floor. Has anyone done this repair? Do I need to add some oil back in somewhere or is it contained in the gear housing part I purchased?

  • Could it be discolored water you are seeing  rather than oil? If the gears are damaged, the lid might not be sealing completely, allowing water to enter and causing discoloration of the water from corrosion or dirt. 

  • there should be no oil in a max air fan.  did you recently buy this?  did some one try put oil onto a fan motor to quiet it down when it was on its way out the door to sell the rv?
