SOURCE: water on the squiral cage side I don't know where its coming from

Water on Squirl Cage could mean clogged spider or media pad not in quite right. Either way the water is splashing of the top of the media and out onto the cage.

SOURCE: Dometic air conditioner blowing cool air

When the cooling slows down, but water is still running off, usually something is icing up. You can turn the unit off, and let it thaw, and try again. Sometimes, if the humidity is high, this is more pronounced. It sounds like you are low on refrigerant. That implies that you have a slight leak. You should have the unit serviced, and the leak repaired.
Best regards, --W/D--

SOURCE: I changed my fan motor and squirl cage blower

If you have changed the motor, I assume that the RPM is the same as the motor you have removed.?
Check the rotation of the new motor, if you have it turning in the wrong direction, it does not matter how fast it turns, it will not send enough air across the evaporator and condenser coils.
Also, if you have changed the motor, you should also change the run capacitor for the power motor.
Hope this info has helped you.

SOURCE: I have a Dometic 579 Series Brisk Air AC.

My sheet shows part # 3100248.420 as fan run capacitor.You may have an updated number. Check voltage outputs labeled on it are same as on old one, and double check wiring is correct, to and from capacitor. Be careful not to mistake compressor start capacitor as well. By sounds of number, it's probably the right one.

Testimonial: "Thanks, your number is correct."

How do I separate the blower wheel housing to replace the blower wheel on a Commercial Cool Portable AC?
Squirrel cage blower, centrifugal, the housing should have removable parts.
The complete side of the housing held on by screws. A round removable flange on the side of the housing held on by screws. A removable flat flange on the output of the housing, held on by screws. The fan motor comes off with the blower wheel. These are different scenarios.
Sometimes the wheel must be removed from the motor shaft before the wheel can be removed from the housing inlet or outlet after removing any flange on the way of the wheel. Handle the blower wheel with care, it is balanced.

How do i remove the squirrel cage type blower fan.
Most fans of this type have a cover between the motor and the actual fan. The cover is usually metal, sometimes plastic and usually has 4 or more screws holding it down. Remove the screws and the fan and cover will come out as one assembly (Sometimes there's a rubber seal between the cover and the housing that may be sticky you may have to gently pry up around the cover to free it from the base its screwed down to). To remove the motor you need to remove the squirrel cage from the shaft, then the cover can be removed and the motor replaced.

Amcor model PLM14000 E INTAKE BLOWER WHEEL NEEDED
All I could find was a Owners manual for this unit. If you have the pieces take them to a air conditioner contractor and ask them to find you a generic replacement blower cage.
You can expect to pay for their time.
Warning...Some contractors will not provide parts to a customer without charging a service call.

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.

Dometic ac model # 57915.741 Ac is vibrating bad when on.
Hopefully there is just something in the blower wheel. Unless you can get to it from the ceiling of the RV you will have to take the cover off the unit to get to the blower assembly. The blower is the front fan that blows the air in to the trailer. If you can get the grilles off of the ceiling, turn the unit off and use a flash light to see if there is something stuff up in the actual blower or the assembly.

Hws18vh6 model # when in heat squirl cage rubs and is very noisy
It sounds to me like you need new bearing on your blower. Also before I did that I would check to make sure that a set screw didn't come loose allowing squirrel cage to slip to one side and rub. Hope this helps. Thank you

The air conditioner has a roar so loud I can barely here my TV.
This roar sounds like the bearings going bad on the electric blower motor.. Does the unit cool just fine ? If so then the blower wheel that moves the air is rubbing against the cage and needs to be adjusted. Turn power off to the unit and remove the front cover where the motor is.. Spin the fan wheel by hand and see if it is hitting the sides.. If it is the cage with motor is being held in usually by one or two screws at the front on the top where the cage is suspending from. With theose removed the cage will slide out and usually wiring can stay connected. There will be a square head bolt that is keeping the blower wheel in place. Spray some penetrent on the threads and let sit for a few minutes. Then use a box end wrench or crescent wrench that is the correct size and loosen bolt by turning counter-clockwise.. WHen wheel will spin on shaft see if you can tap the blower wheel in the correct direction to loosen from hitting the cage. Connect everything back in the opposite manner of course.

I changed my fan motor and squirl cage blower hooked all wires back like they were fan is not turning fast so the compresser is heating up. the old motor the motor mounts went out that why i changed it
Did you replace the capacitor, if not, is it the same mfd and volts for the new motor?
Anytime you replace a motor you should replace the capacitor they don't last as long as they used to and they are inexpensive, a couple of bucks.
If the capacitor is good then most new motors now have the wiring connectiions on the motor, you might check to see if the new motor wires the same as the old motor.

Whwn i turn the heat all the way up loud clicking noise if turned lower noise stops what could this be notfan
I think your talking about the heater fan? If you hear more noise as you increase the blower speed, there is something in the squirl cage or a problem with the blower motor itself. Leaves, paper or something lite on the pass side floor, it will get sucked into the recirculation duct,causing a noise.Remove the blower motor and clean out any debris, and inspect the squirl cage and turn the motor by hand to see if you hear any noise

Noice level high. Vibrating noice
Hi there. Clean both fans if dirty. (inside and outside) Check for foreign objects like insulation caught in the squirl cage blower. Make sure unit is level. Check for vibrating tubes.
Thanks
