Hi and welcome to FixYa. I am Kelly.

First off... some thing has cause the vibration to damage the spider brackets to begin with. Could have been an imbalance of dirt build up on the squirrel cage blower, corrosion.. or a bad bearing.

There are few ways to fix this but all require the unit blower assembly to be removed and your still going to have to balance the fan before re-installing the blower.

Here is the parts list:

Ths spider is not listed as a replaceable part.
You can have the brackets repaired at a weld shop however... welds have a tendancy to make the parent metal hard and if there is any hint of a vibration post repair the problem will only repeat.

I have never had much luck with a unit that got out of balance and caused support bracket failure.
They always result in call backs. The best remedy is to replace the blower. Good luck finding one as most parts for this unit have been discontinued. I am sure there are heating and airconditioning places that have a viable replacement blower that will most likely be a used one.

The blower wheel is roughly $93.00.

I am just passing on my 40 years experience dealing with swamp cooler issues. Having it welded may get you 2 or 3 more seasons at best but you must deal with the balance problem.

Thanks for choosing FixYa,

    Glad to hear a successful result. Most vibration issues are caused by dirt build up on the blower wheel. Your cleaning it up certainly makes a huge difference. Good job on the repair and good end result.

I have a trailer with a duo therm ac..the outside fan is coming on but nothing is blowing thru the registars

Not sure where your located, so check that unit didn't freeze up on you. Make sure evaporator and condenser coils/fins are clean and run on fan only to aid in thawing them out. Once you see condensation running off roof good, try using cool again and see what happens. When they freeze up, airflow gets restricted through unit. The outside fan and blower wheel for forced air inside are attached to same motor, so if fan is working, blower wheel should be turning as well unless it is broken, or allen key has come loose on clamp around center of blower wheel. Other possibility is that the blower wheel is turning but forced air ducts have blockage at inlet, which will require letting ceiling assembly down to inspect, or removing cover on roof and screws at front evaporator and opening it up. Make sure power is off during inspection.

We think there could be a bearing going it is very noisy and the drum seems lose.

It is more likely the bracket that holds the drum to the spindle - oftewn called a 'spider'. This has three or four 'legs' - if you look at the back of the drum you will see the indentations in a star pattern. One or more 'legs' has probably broken and so the drum is no longer able to spin centrally. The spider can be replaced by a washing machine repair engineer. Do not continue to use the machine unitl it is repaired because a loose drum will cause additional damage (mine wore through the heating element).

Flap on ice lever in refridger door is loose and stops delivery of ice out the spout

Remove the dispenser cover by gently prying starting at the bottom going round and round a little at a time to prevent from breaking it. When it's off the screws will be exposed to access the other components.

The hinge on the door could be broken or the bracket it goes in could be broken. You'll have to look to see what's wrong.

* Recover AC gas or empty it in open space
* Drain radiator coolant only
* Remove instrument panel for access
* From under the hood disconnect AC pipes at the evaporator , by removing bolts , discarding O-Rings and make sure to install blanking plugs so that no dirt goes in.
* Disconnect heater hoses from heater matrix pipes , by releasing the spring band clips and make sure to blank the pipes
* From inside the car , remove driver footwell duct , by removing the screw and then removing the duct
* Remove upper steering column lower fixing , nuts and bolts
* Remove upper steering column upper fixings (Bolts) , and allow column to rest down o the floor
* Cut cable tie which secures console harness to LH blower duct
* Remove LH fan motor duct (screws)
* Remove passenger side footwell vent (nut)
* Cut cable tie securing console harness to RH blower duct.
* Remove RH fan motor duct (screws)
* Disconnect Heater/Cooler Connector

* Remove Heater/Cooler assembly fixing , by removing lower nut and upper nut
* Remove tape securing RH rear footwell intermediate duct joint. Remove duct to clear access

2- Remove AC control module 3- Remove evaporator pipe seal plate 4- Disconnect heater tempreture sensor 5- Remove footwell servo motor from heater/cooler unit * Disconnect connector

You are done , make sure to replace all seals that you see to make sure that every thing is ok and you do not have any leaks after installation.

Do not know how to work/maintain swamp cooler

Make sure you have water to the unit, the water pump is on and the fan is working. No water=no cooling.
