Question about Electrolux EL7020A Oxygen 3 Ultra Canister Vacuum Cleaner Bagged Vacuum

2 Answers

I have a Z5930 vacuum and i want to trace an electrical fault. I need to disassemble it to get to the electrical connections and it is quite a tricky one to get in side. The machine will run and then cut out after a short time. It will then re-start in about 2-3 minutes and run normally again and so on. I was not able to give you the exact model but it is Ultra Filtration Oxygen line

Could be a dodgy switch, mains cord or connection but description sounds most like the motor is running hot and the thermal breaker is shutting it down for safety. Assuming the motor isn't faulty it probably hasn't enough cooling air flowing through it. Some cleaners have a separate cooling airflow for the motor but most domestic models use the main airflow which can be restricted by a blocked hose or clogged filters.

I can't tell you how to take it apart but I can advise you from experience there are often screws hidden in the most devious of ways and even after all the fastenings have been removed the casing often has to be wrestled apart so in order not to damage the plastic (much) it is a good idea to keep the assembly in a warm room for a few hours before disassembly.

This sounds like an overheating issue. The motor is most likely protected from heating, some use the airflow through it for ventilation and cooling the motor. Then there is a thermal circuit breaker.

You will need to replace the hose, which has the on off switch built into it, and this will solve your problem

Check all the wiring connections to make sure they're tight.
1/2. Wiring to power nozzle motor or reset switch is loose.
1. Cord from power nozzle to upper wand. If the plastic portion of the wand is cracked near the cord connection, or the connections are blackened, they need replaced.
2. Wiring connection from hose handle to upper wand. Check for cracks and discoloration as in 1 above. Replace if necessary.
3. Hose connection to vacuum. Not likely, but possible.
4. There could very well be a break in the hose wiring.
You may need to take your vacuum, with hose and power nozzle, to an authorized Aerus Electrux service shop. They can try a new hoze to see if that's the problem. If there is a break in the wiring, the hose is probably worn in other areas as well, and should be replaced.

Kenmore Progressive Vacuum electrical issue. My


It could be the wires or switch in the hose and/or the connection between the hose and the vacuum. It could be the power cord or a loose or bad wire inside the canister. It could be the carbon brushes in the motor are worn out. To find a short or electrical problem you need to know how to trace the power flow from the plug and cord all the way to the motor. You can test the wiring in the hose with an electrical tester to see if there is a problem with it before you purchase a new one.

Broken trigger on dc31


I had the same problem where the trigger doesn't always work (it works if I turn the unit upside down). I've since worked out it's the battery contacts which just needs a bit of a clean. It works now no matter which way I'm holding it.

No electrical continuity within the hose of my Hoover S3670 Vacuum Cleaner. How do I disassemble bothe wnds that house the actual connections?


Those hoses are pretty close to being a sealed unit, and was meant to be replaced and not repaired. That being said, some people do fix the problem IF they can locate the problem close to either end. Most people won't mess with an open in the middle of the hose.

Unfortunately, since they are designed to be a replaced item and not a repairable item, there is no written instruction on disassembly. So it is one of those to times when you study your hose and figure out when the break is and then decide on if it is worth attempting a repair.

Has power but won't turn on


sounds like either a bad switch,bad wire or a bad motor -- use a volt meter to trace power out to find what is at fault.
if it turns out to be a bad motor or switch -- you can get the replacement parts at your local vacuum repair shop.

How do I change the electrical cord? It has broken off right at the unit.


If you can disassemble the vacuum and get to where the wire goes into the machine, you can probably repair this.
Once you locate the wire inside the machine, you either have to disconnect the wires from the switch at the terminals or if there is a place where there is room you may be able to use wire nuts to splice the wires together.
Strip the cord coming into the machine, remove about 1/2 inch of insulation from all wires and connect matching colors.
Use normal electrical cautions.
Let me know how you do or if you have more questions?

My filter queen majestic quit working. I opened up the unit to see what was wrong and I did not immediately notice anything wrong. Upon furter examination I noticed one of the traces on the printed circuit...


I recommend replacing the card. Soldering involves the risk of further damaging the card, so it would be useless anyway. Why waste valuable time?
There is a possibility of the motor overheating, generally due to a blockage in the airflow system somewhere. Check all filters, hose, wands, and power nozzle for dirt and/or clogs.
Check wiring connections, including hose to wands to power nozzle. Check all switches.
It sounds like you know how to do this, but if you have any questions, repost.

Quit running I checked all electric and it has electric running to it reset button won't reset it it just doesn't run


a newer model unit (withing 5-7 years) has a deadman switch inside. This means that if the filter is out of the machine or not in properly it will not start the motor until the filter is back in its proper place.

If it is an older model, what you can test is the low voltage lines coming into the unit. Where they go into the unit (usually red or black circular with the two "phone wires"), take a screwdriver and touch the two wires with the screwdriver. What you are looking for at this moment is either a "click" or the motor will start.

If the motor starts, great, now you have to trace the wiring and see where it went bad.
If the unit clicks, its possible it is your motor.

Either way, good luck.

I was using kirby g5 and I think I stepped on cord and lost power on vacuum. Now it won't start. Could this be a damaged cord..or what?


either that, or it was pulled so hard, it came disconnected from the vac switch. stepping on a cord rarely affects power. so, check vac switch and outlet to make sure the outlet has power.

(if you know an electrician or if you feel comfortable disassembling the vac i would look at the point that the cord enters the vac and trace it to the switch looking for obvious breaks)

I have a red c velvet. My vacuum keeps shutting


Could be you have a filter issue and it is overheating and shutting itself off. Make sure you have not put on the wrong filter type for the machine. Some of the pieces that come in the FJM boxes are not actually filters and people make the mistake of putting them on as filters. The other major problem that could be happening is that there is some problem with the hose itself. On my vacuum it will shut itself off after 2-5 minutes, but the power light remains on. I have to press the up button to get more suction, but that only lasts until it shuts itself off again. If I unplug the hose from the cannister... the power comes on fully and the vac never shuts itself off.
A tech told me that the likelihood is that there is some component or connection in the hose control that is causing faulty shutdown. He told me I would need a new hose costing $175. After a year of trying different things, I am convinced he is right and we need to bite it and just buy a new hose.
