Troubleshooting Answers

  1. The vacuum power unit does not turn on.

    Check to make sure that the power unit electrical cord is plugged in and that there is electric current going to the electrical inlet by plugging in a small appliance such as a hair dryer.  Check your circuit-breaker box to see if a fuse has been blown. If you pass these checks and still have a problem with no power, try turning the unit on with the manual on/off switch located on the power unit. If the unit does not power on, there may be a problem in the power unit itself; schedule a service call. 

    If the unit does turn on, there may be a problem with one or more of your wall inlets or your hose end fitting securely in the wall inlet. Call us!

  3. I'm not getting enough/any suction power.

    Check the inlet located on the power unit to see if you have suction at the unit--place your hand over the opening and gauge the pressure created by the suction. If there is no suction at the unit at all, call us. 

    If you do have suction at the unit, check the suction at each of your wall inlets, with no hose inserted. Each inlet should have the same amount of suction as at the unit itself. If one or more inlets have less suction than at the inlet, it is likely that you have a clogged pipe; schedule a service call. 

    If the inlets have good suction, check your hose for clogs by dropping a marble or other object smaller than the hose diameter through the hose. If the hose is your problem, you can bring it into the shop or ship it to us for repair or replacement. If you need further assistance, call us!

  5. My power unit will not shut off.

    If you have a skilled DIY-expert in the household (e.g, you have installed the system yourself), there are three potential sources for this problem that can be checked: a faulty wall valve, a faulty relay in the power unit, or a shorted wire.

    Normally, we recommend a service call to diagnose and fix the cause of this problem.

  7. My doorbell stopped working.

    The source of this problem may be in the door speaker unit (which includes the doorbell). The DIY-expert in your household can easily remove the unit to check it; two screws hold it in place. Once the unit has been removed, inspect it visually for signs of wear or deterioration; if it looks rusty or weathered, that is the source of your problem. Bring the unit into our shop for replacement.

    If the unit itself looks to be in good condition, the problem could be caused by a faulty chime module or an open wire. Please call our office and schedule a service call; this repair can normally be done on-site.

  9. I get a great deal of static when I use the radio on my built-in system.

    This usually occurs as a result of a poor ground or dirty switch contacts. A service call is needed to diagnose the cause and provide a solution.

  11. The revolving brush stopped moving on my upright vacuum.

    Check to make sure that the belt that holds your brush roll has not broken or slipped off. Also check to see if you can clear any debris from around the brush roll that make be causing it to bind up and stick. 

    Belts do wear out; if it gets stretched, the brush roll will not turn properly. Stop in our shop to purchase belts or we can mail them to you.

  13. I don't seem to be getting any suction.

    If your portable vacuum has a bag, check to make sure that it is not full. Bags should be replaced at least monthly in most households. 

    If your vacuum has a hose, check to make sure that nothing has been caught in it that may be creating an obstruction; drop a marble or similar item, smaller than the hose diameter, through to check. 

    If your vacuum gives off a "motor" smell as it runs or seems to run louder, it may need servicing. We recommend an annual servicing for most portables to keep them in top running condition.
