Kirby does not start. Electric cord seams fine. Does a Kerby have a fuse?

this video will help you

If you are unsure on how to splice the cord back together it may be best to just purchase a new cord. You can find a new G6 cord and it is easily installed into the switch at the base of the Kirby.

cord is probably faulty

take off the cover over the plug and plug in an IEC plug ( used on computers) and see if it works

I had to replace mine fan yesterday. I broke away some of the outer pieces and grabbed the fan around the center with some vise grips and put another vise grip on the shaft. ( You can also put a hard steel tool of some kind through the hole in the shaft) when facing the front from the attachment side the shaft unscrews when turning it clockwise.It comes apart right in front of the fan where the washer is.

1. Did I get a good price? - YES
2. What would be considered "regular" maintenance on these units?
Replace belts every 1-1.5 years (they stretch over time), make sure brush roll bristles are not worn and stick out of the nozzle by about 1/8 of the inch (more info here). If bags starts stinking - wash it (more info HERE). Keep it clean and store unit with the nozzle raised off the floor (so bristles would not bend)
Other than that - nothing else is really important.

3. Are there any "Normal Problems" that I should be aware of?
If it makes strange crackling sound when you push it while it is OFF and in NEUTRAL - it may need new bracket cam (instructions HERE). Be careful - do not DROP it on the floor. Original G4 nozzle hooks (that hold nozzle to the unit) are britle and may break. STOP using it if it starts to work LOUD ( fan probably is broken)

4. Any advice for a new used Kerby G4 owner?
Go through the manual - ESPECIALLY section where brush roll installation is explained. We have some good pictures that you may find a bit better than in the OEM manual HERE.

Enjoy,
Rocky

that is not so easy....is it motor bearings or is it the bearings on the rollerbrush...???
