My Beam central vac has started turning off after about 10 minutes of use. I thought it was the hose, but the hose in the garage does the same thing, and I've also tried the other outlets, and the same. The canister was just emptied about two weeks ago. I have also reset the breaker, and unplugged and replugged in the system. Could this be a bad motor?

Re: problems with Beam central vac
First your moms vac. If it has worn brushes only, these are generally easy to replace. However if the wear surface is worn like an apple core, concave, the new brushes will not seat or fix the problem, so remove the motor and inspect before wasting money on brushes. On low RPM heavy duty motors the brushes generally are easier to replace, but a GOOD repair tech will run them in at half power allowing them to seat. One trick is to gently file the upper and lower edge of a new brush, very slightly at about 45 degrees.
Your vac. You have two low voltage INLETS which have either dirty or worn contacts inside. These are spring loaded brass contacts. They can become dirty, stuck or the tension springs can be lost if removed for painting or renos. Replace and test one at a time, should cost no more than $20 fro 2. Wiring is low voltage. Be sure not to fully remove the conatct screw on the new valve when attaching the wire. Wrap the wire neatly clockwise around the screw and trim any excess. Reinstall with the inlet door closing DOWN,where possible. You will have two screws, a long and a short.The short screw goes to the side of the valve where the pipe lays. IE in in the basement the pipe generally travels up, so the sort screw sits on that side so as not to pierce he pie.

You will need a new motor, not brushes, as the worn motor will tear through new brushes. Search online for the M&S motor replacement and you will see helpful sites that will provide the replacement motor. Replacing the motor is not difficult. Consider replacing both motors as the second motor will go out in the near future.
You appear to be describing a case of motor brushes worn out. They may be replaced on some motors, but if there is damage to the motor armature (the rotating part the brushes contact) rhe brushes mayu not last long.
My guess would be that the motor is done. Impossible to diagnose for sure without seeing it of course. If you were happy with the unit before the trouble, a replacement motor will probably run $250-$300. If you are interested in a new unit, shop around. There are definitely better designed and more powerful units out there, although some of them can cost quite a bit more than $300. Good Luck!!

Every time I try and restart it, it immediately pops again. What's the problem? Circuit board? Motor? Overheating? Hello, I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. Chances are it is the relay switch on the inside of the Beam Central Vac, if it was a motor, it would not turn on @ all. If it was a circuit board, it may or may not be turned on, but if it will turn on and then pop your circuit breaker than it probably is the relay switch. Please, check with your local Beam vacuum cleaner dealer in your area or contact the Beam website or cust serv @ the phone number listed below. So if you need further assistance, please feel free to contact your local vacuum cleaner dealer in your area or in the yellow pages, or contact the factory phone number or website to further assist you with your questions. http://www.beamvac.com/usa/Owner Support Customer Service 1-800-369-2326 Phone # Email: firstname.lastname@example.org Technical Support:email@example.com Thanks, Don the Vac Man Go Ahead.

It is possible that the low voltage wiring that controls your central vacuum has been damaged during the cable work. You can check to see if the low voltage relay is working by shorting the two terminals together at the unit. Just disconnect the two small (18-22 gauge) wires from the unit and short across the terminals where the wires connect. If the unit comes on, the vacuum is fine, and it is most likely the low voltage control wires that have been damaged. It should be a pretty easy fix, if you can get to where the wires are located. They are probably just pulled apart at a joint. Good Luck!!

It has supervalves. The handle (connected to the hose stopped turning on the unit. The handle still powers the brush but no longer turns on the suction? Hello, I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure. The Beam Central Vac may have more than a one year factory warranty and it sounds to me that you may have a bad relay switch the Central Vac, if you do it should be covered under the factory warranty. Otherwise, you may have a bad supervalves or a wire came loose, if the hose switch turns on the power nozzle then it may be a bad supervalve or a bad relay and to contact the installer or the manufacturer of Beam.

I work on many types of units. If you electric floor brush runs but you have no suction then there is possibly a problem with the relay board that allows you to turn on the suction from the hose handle. This is a low voltage (24 V) switching loop circuit that will cause the 120 V motor in the unit to run.
Inside the wall valve are two brass pins. NOTE: there are 120V valves installed on some systems known as a Super Valve. A shock hazared exists if you work on that type of valve. That being said. In the round portion of the valve you can use a garage hose that has a 360 deg. chrome ring to test the valve. The ring completes the circuit causing the unit to power up and suction at the end of the hose. If the suction is weak, there is a colg in the pipe. If you hear no airflow, the relay inside the unit did not energize or the motor is bad.
To test: go to the unit and turn the switch on the side to "manual" if the unit turns on the motor should be ok. DO NOT RUN THE UNIT without and open valve. In some brands dammage to your motor will occure.
If the unit did not run, look for a small button near the switch. This is a circuit breaker for the motor. If it is poped out and you hear a "click" when you press it in there is most likely motor problems and someone should be contacted for repair.
