2017 Tiffin Allegro Bus - well this will be a lengthy post. Squirrel cage issues started in July. To date I have replaced ten squirrel cages and three blower motors on our three Colman MACH 8 series air conditioners. Documented each damaged squirrel cage by picture, date and time and it seems to never end. I have also checked every nut and bolt, nothing loose but continueing to see cracked squirrel cages. The word "frustration" is an understatement as it is clear the entire design of the squirrel cage is substandard. I have called AIRXCELL multiple times without a single response but I continue to work with Tiffin on the issue. I also had a lengthy discussion with Grainger on an aluminum squirrel cage and the closest one they make does not fit. I am considering having a one piece squirrel cage designed and made from aluminum to hopefully solve the entire issue. Also, considering an alternate air conditioner for my bus but that is a work in progress. I continue to see post after post on the same issue and seems like the dog is continuing to chase its tail and everything is a band-aid fix. To make matters worse, we have to turn the air conditioners off any time we leave the bus to ensure no additional catastrophic failure. Curious to know if anyone has been successful in ending the dreaded squirrel cage issue on their motorhome.
