When I picked up my new Momentum 23G last month from the dealership, during PDI the motor on the fantastic fan in the living area would just spin and the lift mechanism would just ratchet like it was slipping when it was trying to lift the vent cover. That was written up as a warranty fix and dealer was going to order a new one and have me bring the trailer back to fix it when the part came in. Well I live 90 miles away from the dealer and I really didn't want to take the trailer there just for that (two 180 mile round trips and time off from work), so I watched some videos online and I figured out what the problem was...at least the part that broke at first and not the real cause.
I unscrewed the fan cover and dropped the electric motor to get to the lift arm and pull it out. Sure enough the casing had split (see attached picture) so the gear pushing up the arm would just pop out of gear and not lift the vent. After pulling out the broken lift arm I tried pushing up on the vent cover and it didn't want to move, so I went up on the roof and found the real problem. Whoever put on the self-leveling sealant around the vent got a little carried away and got it all over the hinge for the cover, which is why the vent cover wouldn’t open which caused the lift arm to split open because of that resistance. So I removed/cleaned off all the self-leveling sealant off the hinge and got the vent cover to open freely. I then ordered a new fantastic fan lift arm (part # K0811-5).
Fast forward to today and the lift arm came in and I installed it without much issue; however, when I went to turn the fan on the controls really didn’t want to work right. After a whole bunch of head scratching and research online I wasn’t getting anywhere so I took off the new lift arm and compared it with the broken one. They are the exact same except for one very important difference, the new one raises the arm/vent cover when the motor turns counterclockwise and lowers it turning clockwise. The stock broken one works the exact opposite (clockwise raises the arm/vent cover and counterclockwise lowers the arm/vent cover). So I can get the fan to work, but I have to press down when I want the lid to go up and then up when I want it to go down…very frustrating.
The help I’m looking or here is I cannot find the model number of the fan to figure out what the correct lift arm to order would be so the fan functions correctly. Attached are some pictures of the fantastic fan and the wall controller. Sorry for the long-winded post, but there was a lot to explanation needed to set up this question.
