Beam Vacuum Unit Services Q&A

Most electric hoses will have a bleeder valve located near the hose handle. If you have this feature, by opening the valve you will be able to decrease suction to your carpet. Another option is to replace your electric carpet brush with the newly redisgned Response II CT23 Brush with Wand #489T, which allows easy cleaning for high density pile carpets, such as nylon and other plush carpets.

We do not have specific motor replacement instructions for Beam Serenity Plus system. However, please review the following general guidelines on how to replace central vacuum motors:

How to Replace Most Central Vacuum Motors
(Professionals are recommended to perform this procedure.)
SELECT THIS TEXT. COPY & PRINT IT FOR REFERENCE.
NOTE: Lamb Ametek Vacuum Motors are in nearly all central vacuum brands. The motors sold here are new, genuine Lamb Ametek replacement motors.

1. Unplug the vacuum unit from the wall. If it is hard wired turn off the circuit breaker.
2. If the motors are on the bottom of the unit take the unit down, remove debris bag, and turn the unit over. Disconnect the low voltage wires, if needed. They are small wires that follow the PVC pipe to the unit.
3. Gain access to the motor compartment. (If motors are on the bottom, there is usually one screw on the bottom and/or one to three screws on the side.) Usually the motor shell will not come completely off but can be moved enough to easily access the motor(s).
4. Notice the two or three wires coming from each motor. Disconnect each of the motor wires, or cut them in the middle where you'll later splice the new wire using a wire nut.
5. There are usually two or three bolts, screws, or springs holding the motor down. Remove.
6. Lift the motor out. There may be a gasket so lift with some force. If the motor has an exhaust port, slide it off or unscrew the bolt. Save it or buy another Motor Exhaust Coupling #507EX .
7. If needed, clean off the old gasket from the motor compartment and place the new gasket on the motor with the sticky side on the motor. PLEASE NOTE: if your original gasket is not a thin foam pad they REUSE your original gasket no matter what.
8. (Before anything is done with the motor check to see if it compressed in shipment. Reach a finger in and spin the fan. Listen for any scraping. To correct, use a screw driver to push the seam of the motor shell down a hair.) Place the new motor where the old one was taken out.
9. Screw, bolt, or reattach the mounting.
   ***Do not use excessive force or the motor fan housing will move causing the fans to hit the housing when spinning. The seam on the side can be tapped down with hammer and screw driver if needed.***
10. Connect the motor wires. There will be two blacks or a black and a white. The motor will run the same no matter if colors match or not. So don't worry if there is not a white wire to match a white (or black for black), just connect them. Splice the new wires to the old with wire nuts, or use connectors to plug the wire directly on. The green wire is a ground and if your new motor has one you need to connect it to a bolt somewhere on the unit.
11. Plug the vacuum in and turn on the manual switch (or use the hose in the home after connecting the low voltage wire to the unit). The motor(s) should start up right away. Unplug it again.
12. Close the motor compartment and put the vacuum back on the wall (if taken off). Connect the low voltage wire back if removed.
13. Plug it in. Test it again.
14. If you have any problems or questions don't hesitate to call our customer service toll-free at 1-800-997-2278 Mon-Thurs PST.

That is a bad motor. The reason it ran for 40 minutes is because the motor was jarred so much in travel. The motor brushes repositioned themselves. When you get it home it will run for less and less time. Replace the motor and you will be fine.

To first isolate the true issue with your system - which is not the filter - please follow the steps on our Troubleshooting Flowchart. In regards to replacing your filter it should be cloth with a compression ring with weighted center. Pull the edge inward or lift with tool to flex the ring and the filter will fall out.

The symptoms you described is generally an indication of a faulty relay which is generally located on a circuit board. We recommend replacing the board with our Beam Single Motor Circuit Board #235SB.

Most installations can have the exhaust vented. That is too bad. Independent dealers for Beam are not associated with our MD brand and they all of their opinions. The noise should be cut down using a muffler. We have these Muffler Options for Beam Central Vacuum. Please look them over and call us if you have questions.

1. If the inlets are Supervalves (110v valves), plug the power brush directly into the valve. If the power brush works, the problem is in the high voltage lines in the hose - likely a blown fuse in the hose, but also look at #14.
2. Check brush for bad neck tilt, switch, or reset button.
3. Put power directly to brush motor to see if the motor is bad.
4. Check cord connections from hose to brush.
5. Check to see that Supervalves/Electravalves have 110 volts.
