I have an electrolux guardian vacuum model #c154b . I have taken it apart to change the fuse and know the bag light stays on. Not sure if I have the hoses for the switch right. Heres what I have.... red hose was never disconnected from switch and I have run it to top of bagcan. there is 1 long clear hose coming from front of bag door and I ran it to other port on switch. there is 1 extra piece of hose and I ran it from top port of bagcan and can not find anyother connections. Is it just a vent or do I have hoses wrong. should also note that circuit board inside of handle is bad. Wife plugged vacuum with hairspray lid and blew the fuse, not sure when the board went.

Possibly the bag sensor is bad.

SOURCE: vacuum shuts off

if you want to fix this problem gently pry up the air flow control knob and look down at the plastic hose connected below the control valve. insert a small screwdriver and push off the hose from the valve. this disconnects the bag full indicator but will let the vacuum operate normally at full vacuum. you will change the bag when suction gets low. this will save you at least $100 repair bill.

The problem was a sticking switch that was not being reset. The vacuum on/off switch mechanism is comprised of two switches. One is the main switch that turns the vacuum on and off. The second is a shut off switch that gets tripped when the full bag sensor is engaged. This second switch is supposed to get reset when you push the on/off switch on the outside of the machine. The full bag shutoff switch was stiff and it, therefore, was taking a couple of presses of the on/off switch to move the shutoff switch back into the running position.

Turn the knob on the top of the vacuum all the way to the right.I had the same problem and that fixed it.

Did you get new wands with the power nozzel? The wires that power the nozzel run through the wands from the hose to the nozzel.The connectors at the end of the wires are fomous for getting too big and making a bad connection. This causes the on/off problem. This will only get worse if you continued use. The wires in the hose handle, the hose and the power nozzel elbow can all be changed out. You will not have to replace the hose handle or the wands unless the plactic has been burned. (A loose electrical connection causes heat). Take your hose,wands and nozzel to the shop for repair. Don't let the sales/service manager tell you that you need new parts until you can see the parts are bad. I think they saw you comming when they sold you the new nozzel.(just my opinion)
