Electrolux central vac problems
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.
Hope this helps!!
