There is usually a 125V, 20 AMP line fuse inside the microwave, mounted at the point where the power cord enters the back of the unit. Or, on a line filter control power. Unfortunately, you will need to uninstall the oven (if this is an over the range model), UNPLUG it and remove the exterior case to access. The case comes off in various ways depending on manufacture and model. Since you provided no model number, I can only give this basic advice.

If the line fuse is blown, you can usually purchase a box of fuses at a hardware store for just a little more than what the manufacturer charges for a single fuse. 125V, 20AMP Ceramic Slow Blow fuses are recommended.

If you have any questions, or need additional assistance troubleshooting, please post back with your MODEL NUMBER and let me know. I hope you find this information helpful.

NOTE: Make sure you take any resistance readings with the microwave UNPLUGGED and the component under test isolated (removed) from the circuit. These ovens can blow a fuse by simply sitting idle. This can occur from any power fluctuations, brown outs, voltage spikes, etc. Or, it could be the symptom of a component that may have failed. If you find the internal fuse blown and replace it, only to have it blow again, you have a more significant problem than a simple blown fuse.

Check the main fuse and see if it is blown. It should be a 4 or 5 amp 125v fuse. Thanks for using fixya.

You will need to remove the back of the TV. Don't worry, it's not that bad.

There are 4 screws across the top, one on each side, one right next to where the power cord goes into the back of the case, and the two more by all of the video connections **These are the most important to remove because they attach the main board to the back of the case.

Once you have remove the screws then the entire back of the set will slide off. If you look where the power cord attaches to the board you will see a small fuse. This is a 6.3 Amp 125 volt fuse. You can replace it with a 6.3 Amp 250 volt fuse from your local Radio Shack. A four pack costs between $3 and $5.

Make sure that you check that it works before putting it all back together. Check for any loose connection cables while you're back there. I found a few when I did this.

Good luck!

if you plugged a 125 volt tv in to a 220 volt outlet you more than likely fried alof of the componets in the tv. Putting a bigger fuse in there is only going to increase the risk of it catching on fire so i would not recomend that. you might replace the power supply and cross your fingers and hope that nothing else cooked when the 220 volts hit it

This condition, may be produced by defective components (Q506, Q507). you can remove those transistor, replace the fuses, power-on and wait for relays click. if the fuses not blown again, them replace both transistor.

Look at the fuse you pulled out. The rating is embossed on the side or end.

Hello sjday62

It sounds as if you have a component that has changed value enough in value to cause a high current draw, but has not completely shorted out. this phrase from you "so I did a stupid thing and bypassed the internal fuse and it turned on and worked" Not as stupid as you would think because it confirms what I said above, the 6.3 amp fuse tells me that the current draw normally is about 3 amperes since the normal rule of thumb is to double the value of the current to select the type of fuse. a five amp fuse should as well as a 4 amp fuse (it's best and recommended to use the exact fuse type). Now back to your issue. I would suspect that a transformer in the power chain has developed a shorted winding, or a capacitor begun to develop a short or excessive absorption.

I would suggest that you have the set looked at by a qualified TV technician.

I hope this helps,

Thank you,

Hi, If the fuse physically fits into your unit then it will work. However- - - WARNING! Although 6.3 amps on a 250v fuse will allow the current to flow it will not afford you the circuit protection you require for a 125v circuit. If the circuit develops a fault then there is a danger that you burn out the circuit before the fuse. As you have already blown one fuse I would suggest tracking down the fault before you do any thing else.

It will work, the amp rating is most important, 125v / 250v does
not matter.......note: if you blow the fuse again, the TV will
need service.................T.
