How to Identify and Fix Common Vacuum Problems ?

This means the fuse can be used in a circuit he voltage maximum operating at this voltage . For example; if your fuse was rated at 250VAC, it could be used in a 250VAC circuit or in a or less lower voltage circuit such as 12VAC, but it must not be used in a circuit operating above 250VAC ie.
The smallest blade fuse currently available is the Micro Blade Fuse. They are available with either 2 or 3 metal terminals (prongs). The two-prong Micro Blade Fuse is known as a Micro 2 fuse has a current rating range of 5 to 30 Amperes and is 9.1mm wide, 15.3mm tall and 3.8mm thick.
The most common cause of a blown fuse we see as experienced Electricians in Sheffield is when something draws too much power from the circuit. This is most often caused by either too many lights or from using too many plug-in appliances at once.
Plugs for appliances rated up to about 700 watts should have a 3-amp fuse (coloured red).

.A clog in the hose, UR or canister. Detach hose. Drop small coin in one end and lift hose causing it to roll out the other. If it does, no clog in hose. Drop same coin into hose opening on power head. If it rolls out, no clog in PN.
.Broken fan blades, UR. Needs to be taken to shop for repair/replacement.
.A reset button is for use if the motor isn’t running, so won’t have anything to do with the suction.
I am looking for a wiring diagram to install a touch/dimmer switch by “Comfort” mdl # RH-934B – Darjung Ind Ltd.
It has a standard lampcord (two wires) coming from it as well as one white, one black and one yellow wire.
The original touch/dimmer switch (no identification on it) had one white, one black, one red and one yellow – no lampcord.
Thank you very much for your help!
The machine probably requires about 2 amps or less under normal operation.
Being a 3.0 amp slow blow fuse, it will withstand short bursts of extra current when your machine gets temporarily overloaded.
Just make sure the machine is properly lubricated and runs freely. The fuse will definitely blow if your machine should get jammed or something like that.
I think I know where I can score some. Cost of postage only. 🙂

Subject: T3.5/250v glass fuse
Just six months after the warranty expired, I was vacuuming when it suddenly stopped. There was no blockage in the tube and it wasn’t working hard or long . . . it just stopped.
I looked around the Internet and it appeared that many similar Electrolux units have a fuse. I hoped my problem might just be a blown fuse, so I took the machine apart.
There are two small printed circuit boards, but no fuse. There is an in-line
.I don’t think you need a new motor, but please stop testing the machine with live power. It’s dangerous and unnecessary. Your tests indicate to me that the motor is fine and your thermal-fuse – I think this is what you referred to as “thermatrol” is blown. I assume you used an ohm-meter to test the continuity across the brushes? If so, and the reading was 0 ohms accross the brushes, then your motor is fine. Also, the 120v reading at the motor terminals with the power on shows that you are getting power to the motor. The reason there is no continuity at the motor terminals is because this circuit is routed through the “thermatrol”. If the thermatrol is open-circuit, i.e. blown there will be no continuity here.
.If you need parts, I can probably help you find a supplier, but let’s establish which parts need replacing first! Please confirm the resistance readings from the brushes and we’ll go from there, but no more live testing please, particularly the 120v A/C direct to the motor from the wall socket!
