Air Conditioner Vibrations

[raebaker06]

I turned on the air conditoner and it vibrated severlly. On taking off the shroud the shroud began to brake apart DARN PLASTIC... I ordered a new one from Coleman and they shipped it immediately.
On examining the unit I discovered that mud dabber wasps had build their homes on the fan blades. this caused the unbalance and the vibrations in the fan.
The fan is made of Plastic (Blessing upon Coleman) and they cracked. I ordered new fans and with much distain I installed the new ones. I replaced both sets of blades because of the plastic . I would suggest that anyone who has one install a screen over the fan compartment to keep the critters out.

Rae,

Let me be the first to thank you for posting your AC situation. Mud daubers are the bain of anything that sits outside, and your specific course of action to your situation is much appreciated.

Mud daubers have built in the heater intake/exhaust and yellow jackets nest above the belly wrap. This is a new one. Thank you for expanding our horizon, Rae.

On a different note -- if you read the least bit in these forums you will take the following with a grain of salt, a bitumen of bile, and a whoosh of whimsy: I know you are parked and unhitched when the AC is going, but is there any way that this could be residuals from vibration caused by unbalanced running gear, wheels, axles contributing to the proverbial rear-end separation? (not that being an early-ish baby boomer has anything to do with the latter....)

Moral: Don't just take off and run with your babies. Observe! Mud daubers - it's their season. Yeah! Watch out for 'em!!

Not sure of what you speak. The vibrations I talked about was in the squirrel cage fans inside the airconditioner. Also there could be a case when the clamps that hold the fans to the motor shaft loosens. You would have to open the entire unit and tighten the screw that hold each fan. If you choose to run with the vibration you can damage the cage, and possibly the motor.
Remember that on Airstream products a $10.00 fan costs $ 100.00.
Anything that vibrates needs to be attended to right away.
