Question:

When to replace Rainbow PN-2 power nozzle motor?

We have had a rainbow vacuum SE for several years now and the power nozzle recently started not working as well as it should. We have replaced the belt and cleaned the brush, but nothing has seemed to help any. Is it time to replace the motor in the power nozzle?

Answer:

.Well maybe the configurations of motor is not the same, meaning it is wired differently. I personally would be taking it to Electrician as last thing is having a dangerously wired cleaner... Earth missing on motor is a worry as I said take it to a professional keep away from DIY in this case..?
Hi there, Your post doesn't say exactly how your current power nozzle is working at the moment. But i'll give you a general answer anyway. I am a technician for vacuum cleaners (and an authorised agent for rainbow). Basically there are two possibilities for the problem. The first is the bearings for the brush roller. over time the bearings can wear and stop allowing the brush to spin properly, this puts strain on the motor and can cause damage to the brush and roller. It is simple to diagnose though. Turn on your power head as per normal but with the base plate removed so you can listen more clearly. Then take the brush out so the motor is just turning with no load. If it sounds smooth with the brush out then it is more likely that it is the bearings for your brush rather than the motor that needs replacing. As a side point even if it is the motor that is noticeably faulty, it is worth replacing the brush bearings anyway so you get the best possible improvement from your work. The bearings aren't dear to buy anyway. If you need a place to buy the parts for your rainbow vacuum cleaner you can visit the sites below.
