A/C Fan

I have always had a problem with the fan in the rear A/C seizing. I can get it going by playing with it from the inside of the coach. This is a pain in the neck. (Literally) Can I not get to it by just removing the cover on the top? Is there any trick to that or is it just straight forward?

I think that you should be able to get to the fan from the top, but don't remember. Removing the covers is just 4 screws.

Ted - You can get to it from the top but there are a bunch of screws you need to remove from shrouds around the fan and compressor. Once the shrouds are removed you can get to the fan and motor to determind what is causing it to bind. This is assuming your newer AC is similar to mine.

You can get access to the fan/motor from under the top cover but am not sure what you will be able to figure out. The fan/motor assemble consists of a single motor with two cage fans mounted on either end of the motor shaft. If the motor is freezing, its probably an internal motor issue or a capacitor/controller issue on the mother board.

I find that either of my ac fanss will sieze after a prolonged period (>month) of non-use. I try to remember to run both ac's when I exercise my generator; which should be monthly. The same is true for the fantastic fans that I converted to remote control. They tend to bind when opening if not exercised at least once a month. I hope that is all you need. Good luck.
