remoandiris Posted February 25, 2020 Report Share Posted February 25, 2020 Does the squirrel cage get replaced from the bottom or the top? Searched Youtube for vids but didn't find any. Neither of my manuals show any repair processes. Coleman/Airxcel sites didn't help, either. Quote Link to comment Share on other sites More sharing options...
GlennWest Posted February 26, 2020 Report Share Posted February 26, 2020 Fan should be up top. Too much noise on bottom. Before I junked mine I put several fans in mine.

Before I junked mine I put several fans in mine. The squirrel cage is easily visible from the bottom. Just to clarify, this is the squirrel cage that blows the cold air thru the ducting into the coach. It is NOT the fan that blows the hot air out of the shroud on the top of the RV.

Al F Posted February 26, 2020 Report Share Posted February 26, 2020 I would pull the shroud off of the top of the AC and look. Should be some sheet metal to be removed to access the squirrel cage. I can't see how you could access the set screw attaching the fan to the motor shaft from the bottom.

GlennWest Posted February 26, 2020 Report Share Posted February 26, 2020 On domestics it is the same fan. Coleman I would think same.

jpatrickc Posted February 26, 2020 Report Share Posted February 26, 2020 If It is the same model Mach as I have the squirrel cage is replaced from the top. The insulation in the chamber with the squirrel cage had come loose and was hitting the blower and causing a scraping noise. It is a pain to get the housing apart and I had to move the finned coil to get the motor and blowers out of the housing. I didn't need to remove the cage fron the motor shaft but If it is like the home furnace squirrel cage blower I replaced you need to be sure how far it slides on the motor shaft. I forgot to check before I losened it so I had to move it a few times until I got it that it didn't scrape the housing when running when I did mt home furnace. It is probably less than an hours work. There was some of the aluminum foil duct tape on the housing that I had to remove so you might need some of that to seal things up during reassemble.

The exhaust fans on these have their own historical issues. Quote Link to comment Share on other sites More sharing options...

I have to give it a few days for weather to settle. At least it is not hot. Quote Link to comment Share on other sites More sharing options...

I mentioned in my initial post, I searched youtube and came up with nothing on replacing the squirrel cage on a Mach 1. Sure, there are vids for other rooftop systems, but it didn't give me anything for the various search parameters I used. Well, I did a couple more searches and I guess I hit the right keywords. Found a vid that had most of what I need. Should be able to do the job once the weather breaks. THANKS!!

Al F Posted February 28, 2020 Report Share Posted February 28, 2020 About 1 fan or two fans, or two different fans. Most likely, one motor with the shaft coming out both sides of the motor. One side goes to the fan for the condenser unit and the other side goes to a squirrel cage fan to circulate the air inside the RV.

remoandiris Posted March 3, 2020 Author Report Share Posted March 3, 2020 Replaced the squirrel cage this morning. Took under an hour, including the time to get my tools. 4 phillips head screws holding the exterior A/C shroud, 4 10mm nuts holding the metal cover under the shroud (protects the cooling fins, squirrel cage, and cage motor, etc), and 1 star head screw holding the squirrel cage onto the shaft. Shaft has a washer and a clip holding the washer in place. No way to push the squirrel cage too far onto the motor shaft. Squirrel cage mounting hole is designed to make sure the cage goes on one way. One end is round and the other is oblong to fit the tip of the shaft. Hardest part was getting the star head screw back into place just by feel. Couldn't see it with the cage blades in the way. At least I didn't drop anything down into the unit or off the roof.
