Basement Air Conditioner Problem

Recommended Posts

sasmit8   

We have a Coleman basement air conditioner in our 2002 Winnebago.

Over the years we have had a lot of problems with this unit, and have spent over $4000.00 in repairs.

The latest problem we have not been able to get fixed. The problem is a LOUD NOISE vibration coming from the squirrel cage blower,if you bang on the bottom of the blower.

the noise will stop until the unit stops and recycles. On a trip to ME we had it looked at and they said it was the blower motor. We had the motor replaced at a cost of $750..OO.

That fixed the problem for about 5 hours. Then on a trip to GA we had it looked at again. This time we were told it was the blower motor again caused by not replacing the pillow block bearing when they replaced the motor the first time as the bearing was seizing. They then replaced the motor and bearing for $850.00. This lasted for 3 hrs  use.

We now have the problem back Not sure what to do next.

PS

Our camping neighbors hope we fix this soon.

This information might be of help. At least you can look it over or a member might have some good feedback. Lemp offered a good possibility. I have run into a number of units that squeal.  That noise comes from the oil-lite bearings in the blower motor. They can be lubricated using Silicon based oil or grease. No all the tricky, but takes some time to work it into the oil-lite bushings. 

There are some pictures in the information an if the motor was changed with a new one the noise should have not come back in a short amount of time?

Could you post the kind of noise you are hearing, a Squealing sound, rattling sound or more of a buzz ?

        Reading up on the basement AC units and found out that parts for the older models where discontinued in 2010 - when R-410 replaced  R-22.  You mentioned that the service center replaced the motor for $750.00 -wounding where they got it from? The blower motors should be the same, but the compressor unit would have been changed to work on the R-410 Freon.  Although you did not mention any problems with it cooling. Just the noise. And if it is not a squalling - then it becomes a mounting, balance issue with the blower fan or possible loose motor mount.  Loose,missing screw(s) or damaged squirrel cage fan.  

R-22 is a single-component refrigerant, whereas R-410A is a 50/50 blend consisting of R-32 and R-125. Higher pressure requirements.

I wouldn't spend too much money trying to build a 02 unit!  Colman-Mach now has a new replacement for the OEM unit, ($2655.00 free shipping from Amazon)  available elsewhere at varying prices. Colman-Mach part # 46515-811, Winnebago part# 700050-01-000.  The new unit has the improved R410 refrigerant and is designed to work on 50/50amp service.

Consult Winnebago prior to install as there are some technical changes that may be required for the electrical control monitoring panel.

The Coach is a 2002 Winnebago, but not sure it is wired for 50 amp or 30 amp. shore power. OP did not include the Model.
