Question about Air Tools & Compressors

Open Question

I have a DeVilbiss Air Compresses Model 350E20AD. The squirrel cage broke apart and tore yp the air filter in the process. After removing the cover and cleaning out the pieces the compressor will no longer build pressure. Air comes out of something called a Plow Value. That valve looks like it is designed to let out air but I fail to see how the compressor can build air with air coming out of that valve. I plugged the hole but to no avail. any suggestions before I purchase another air compressor?

SOURCE: Pressure won't build up in tank

Your compressor is the oilless type that incorporates a vinyl/teflon piston ring and a cylinder that is open from the bottom. Remove the cover and push the piston to upmost position. Look for scratches along the upper portion of cylinder. If scratched, compression is leaking thru ring and will not fill tank. Replace with Sears part #k0650 cylinder /piston ring kit to restore full power. While the compressor is apart examing the valve plate and reed valves for wear. If worn replace with part #z-ac-0032. Reed valves tend to crack or loose their shape reducing efficiency. If cylinder and ring are in fair condition, then most likely reed/valve plate is the problem. Good luck and email if you have more questions.

SOURCE: coleman compressor no build up of pressure

Parts for coleman are available at www.mastertoolrepair.com your compressor is listed as L0502710. If however you like to tinker, you can make a pretty good reed valve out of aluminum can material or other (any ideas?). It is fairly easy to cut, does not last as long as factory stainless steel, but for short term, why not? Good Luck

SOURCE: Drain valve in Porter Cable air compressor

this valve works backwards, you screw it out to stop airflow. If that doesn't work, replace the valve.

SOURCE: Was working normal suddenly will not build pressure

Maurader1 an apprentice has this problem solved and is spot on. All these gurus and wiz need to stick to the basic and common sense. The first place your pump will give out after use or abuse is the gasket. All this garbage about defective reeds and defective pressure switch is a lot of nonesense if you first don't rule out the most common problem the head gasket. I'm cheap and this thing has paid for itself 10 time over. You can get a gasket kit for $7, but I fabricated a gasket out of the back of my notebook and sprayed some gasket spray and been working like a charm ever since.

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.

How to replace blower wheel on Friedrich SL28M30 AC unit


follow this steps and fix it. God bless you








    • 1



      Turn the electricity to the air conditioning unit off at the
      service disconnect box. Follow the wires from the AC unit to the
      disconnect box, usually located next to the unit. Open the disconnect
      box and, depending on the type, either pull the buss-bar or flip the
      disconnect switch.





    • 2



      Open the air handler\'s access panels with the correct size of nut driver, usually 5/16- or 1/4-inch. Save the screws.









    • Remove the control panel\'s cover, if equipped, with a nut
      driver. Some models have a flat metal cover over the electronic
      controls, and some control panels butt up to the unit\'s access cover.
      Save the screws and access cover.





    • 4



      Follow the wires from the blower motor. Two wires will go to
      a capacitor located on the blower\'s housing. The rest of the wires will
      go to the control panel.





    • 5



      Cut the wires leading into the control panel with wire cutters. Leave the cut wires connected inside of the control panel.





    • 6



      Remove the retaining bolts with either a nut driver, usually
      3/8-inch, or an adjustable wrench. The retaining bolts, found on the
      mounting brackets that the blower\'s housing slides on, keep the blower\'s
      housing locked into position. Save the bolts.





    • 7



      Slide the blower motor\'s housing out of the AC unit. The housing will slide straight out along the mounting brackets.





    • 8



      Disconnect the two wires going to the capacitor. They will pull straight off the capacitor\'s terminals.





    • 9



      Unscrew the squirrel cage\'s locking-screw with an adjustable
      wrench. The squirrel cage, the bladed wheel, connects to the blower
      motor\'s shaft inside of the housing. The locking screw holds the
      squirrel cage to the shaft.





    • 10



      Unscrew the blower motor\'s mounting screws with either a nut
      driver, usually 3/8-inch, or an adjustable wrench. These screws hold
      the motor to the housing and are found on the opposite side of the
      squirrel cage, the same side that the wires leave the motor.





    • 11



      Pull the motor from the housing. A drop of oil on the shaft
      will aid in removal. If the squirrel cage sticks to the shaft, then hold
      the shaft still with an adjustable wrench while spinning the squirrel
      cage on the shaft.





    • 12



      Slide the new blower motor into the housing. The blower motor\'s shaft will slide into the squirrel cage\'s hole.





    • 13



      Tighten the blower motor\'s mounting screws.





    • 14



      Spin the blower motor\'s shaft until the flat part of the
      shaft lines up with the squirrel cage\'s locking screw. Move the squirrel
      cage in or out until it does not touch the housing or the blower motor.
      Tighten the locking screw.





    • 15



      Connect the blower motor\'s capacitor wires, usually brown or
      brown with white stripes, to the capacitor. Direct replacement motors
      use the same color-coded wires as the original.





    • 16



      Slide the blower motor\'s housing into the AC unit along the mounting brackets. Install the mounting bracket\'s retaining bolts.





    • 17



      Connect the new blower motor\'s wires in the control panel
      one at a time. Disconnect one old wire in the control panel. Determine
      its color and connect the new wire, of the same color, to its place. Do
      this for all wires.





    • 18



      Replace the control panel\'s cover, if equipped, and the
      unit\'s access cover. Turn on the power to the unit at the disconnect box
      and test the blower motor.

I have a New air 1400H and the blower fan has broke, can you tell me where to find replacement parts for this unit? I understand it has been discontinued for almost 5 years. Thanks for your help.Cont


You may have to remove the complete blower assembly, remove any dead squirrels, and take it around to various appliance parts suppliers to obtain a suitable replacement. You may need only a replacement motor if the squirrel cage is intact

Why does my ac freeze up


Hello, air conditioners will freeze either due to low airflow.....such as dirty filter, dirty evaporator coil, weak or not running blower motor. Also, a low refrigerant charge can cause the unit to freeze up.

Coleman RV Rooftop Air Conditioner - cage fan making a noise like it is hitting on something as it goes around. The motor works as it should, low and high fan and cool, the air is cold. The only thing...


Hi,
Those squirrel cage fans have a habit of coming apart, or getting dirt in them and going out of balance...then they wobble and hit the sides of the fan housing...
Make sure the fan is clean and also move it around a bit to make sure it is not coming apart....
Often the only way to fix them is too replace the sqirrel cage part...

Take a long time for blower motor to get up to speed


The first thing I would do is to clean motor and squirrel cage. It would be best if you would remove it and take it somewhere that you had a air compressor to blow out motor ports and fins on squirrel cage. Most of the time you can remove by disconnecting modular plugs and removing two or more screws on rail that squirrel cage slids on.
If you can get it out you can use a fine wire brush to loosen dirt and dust from fins on cage then use air to blow out as much as you can.
Your motor may be getting worn so check the bearing by grasping cage and see how much it will slide side to side and if it moves more then about1/8 inch then you are going to need to replace it before much longer. Also make sure that the rim of squirrel cage is not rubbing on blower housing and if it is then loosen motor mounting screws and adjust ,then retighten screws.
I hope this helps you. Thanks

Goodman ac heat air handler starts noisily for about 30 seconds then stops. Condenser fan is okay. Inside fan works but seems weak. I can't find the model number, so I just picked the first one.


inside the air handle there is a motor and a cage(squirrel). I am assuming this is the problem. The side that has the pilot light, take this cove off first, then the back cover. There is a switch so when you take the back cover off it opens the circuit. You will see a main board and to the left and behind is the motor and squirrel cage. I would kill power and then remove the bolts making sure I make the wires and where they go. Then just take the motor and cage out. You will need a allen wrench to remove cage, then replace motor. Hope this helps Tim
