I have a 6550 that just stopped working. I had the on/off switch tested to find out that it was dead. I replaced it and still the machine does not work. Could the wiring in the handle be bad? How do you test if the motor is still good?

SOURCE: power head

If you have checked the power delivery down to the powerhead and you have current running to the powerhead, then you likely have a burned fuse. There is a fuse built into the powerhead motor and is usually located on the field winding. This is not easy for a novice to replace and even most professional repair shops will replace the motor. It is possible to replace the fuse if you know what you're doing, but if the fuse blew, there may be a more serious problem, after all, the fuse is there if the motor starts to experience distress and the fuse will blow to avoid any electrical issues. The fuse can blow if something is jammed into the roller and causes the motor to labor heavily. If this is the case, then the fuse can be replaced safely. If the motor is burning out, then a new fuse will just blow immediately after replacement. What I do is take the fuse out and run the motor without it to see if the motor is still viable and replace the fuse if the motor proves to be o.k.

I would take it into a local vacuum shop but DONT take it to a kirby shop because they will charge way more

Hi,

Check for either voltage to switch or if your not happy or compettant working on live mains.
Switch meter to ohms ensure vacuum is unpluged from mains follow live wire (brown) from plug to exit point on the back of cable rewinder check for continuity shold be dead short if it is check switch if this is ok move to neutral (blue) wire again check from plug to rear of cable winder.
The neutral then goes off to moter again check for dead short,
I think from experience that you will have A break in either live or neutral in the mains lead going to cable winder.
If it is its realy easy to replace winder they come with lead all ready fitted.
If you need one contact me.

SOURCE: The handle for my Eureka 5993 AVZ was getting very

Had exactly the same problem with my upright Eureka Model 5893 bagless. It almost melted the handle! Ordered a switch after talking to several repair men. Talked to Eureka, too, and they were absolutely no help. Cheap wiring and switch made in China. Good luck trying to find a switch. vacuum-depot.com has switches, so you might try there.

Check the battery contacts... a common problem on this model. they are easily bent and prone to corrosion.
