Hi,

Their would only be a limited number of components capable of blowing the fuse. They would be:

  • bridge diode;
  • filter capacitor;
  • regulator IC;
  • mains B+ capacitor; and/or
  • overvoltage protection (SCR type).
all in the power supply circuitry.

Depending on the PSU design, other load side components can and may cause the fuse to blow likewise. They may include (but not be limited to):
  • horizontal output transistor;
  • flyback transformer; and/or
  • yoke.
Repairs/diagnosis of course would require a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings. Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.
Hope this be of initial help/idea.

Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Voltage change 220v 240v


These number have no bearing with amp issue. It only means if you're in North America or International with 220 volts. However, your problem is power transistors
that are shorted which is the cause of fuse blowout.

Fuse F1 is blown


You don't give any information about the make & model of the machine, but if the fuse keeps blowing, it's probably due to a short circuit somewhere in the machine. It could be as simple as a cut in part of the wiring, allowing the copper cable to touch another metal part, or it could be the compressor or pump wiring shorted out. If you don't have the experience or equipment to isolate the short, your best bet is to call a service engineer.

My sansui 1000 receiver keeps blowing fuses


Fuses blow when there's an overload. This is often caused by the main power amp devices located on the heat sink. If they are transistors you can test them with an ohm meter. It will be just like you have put the two test probes together on the separate pins of the device.

Does not heat


There is a slo-blow 20 amp fuse inside of the ac power panel. You will have to remove the front and locate the fuse inside. This fuse suplies the power to the Traveling Wave Tube that spplies the microwave energy.

Lightning strike Vcr keeps blowing fuses


Fuses blow when there is an overload. Overloads in turn are caused by a semi-condutor device that is acting like it was just a piece of wire. In this case look around the power supply and look out for burnt or damaged parts.

Keeps on blowing fuse


Hello
If fuse blows off repetedly, it shows that there is a direct short inside the power supply section. You just check the mains rectifier diodes for short. iIf a rectifier stack is used desolder it out and check for short. In some sansui sets, ther is a metal oxide variste connected across the supply line inside directly. It is for line spike suppression and an overvoltage protection. If any of the above appears on the power line, the varistor will get shorted, and the fuse will go out, to prevent further damage to the circuits. Check that varistor for short. Check the resistance across main filter capacitor for any direct short. If it seems shorted, check the switching transistor for collectror to emitter leak, Resolder it out and check. These are the main reasons for blowing fuse. If the switching transistor has got leaked, you must check the entire SMPS control section, especially in case of used zener diodes, before replaceing a new transistor. OK.
If you wants anu further assistance, inform me through Fixya. Ok.

Blows fuse when turned on


this is a normal behavior if one of the power supply transistors have blown. take the unit to an enlectronics repair. they can either change the transistors affected (usually more than one) or replace the power supply board.
