GE microwave over the range, model #jvm1740sm1ss has no power.it's only two year old.what could be the cause?


Hello,

the problem of this unit is power related.

First, remove the unit's power cord from the wall, wait for about 30mins, then plug it back in. It may cool by then and might power on. If it doesn't power on, plug it into another outlet, to make sure there electricity entering into the unit.

If plugging into another power outlet doesn't power it on then the unit is most likely having a power problem.

When electric current comes from the power outlet into the cooker, it goes straight into the power supply board which then circulates the current into the unit. So if the cooker doesn't power on, the first thing is to make sure there is power entering into the machine.

So check the power cord, if it is a 3-pin plug, it must have a fuse in it. check the fuse if it is not blown. if fuse is intact, then power supply board should be checked.

If any machine or electronics device doesn't power on, it means its having a power problem. it might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby not making it to power on.

This unit must have a power supply board in it where power enters from the mains. A capacitor, fuse, diode, etc may have been defective on the power board and maybe that's why its not making the unit turn on. There might also be some disconnection or something, inside the unit which is not making it to power on.

To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter and continuity tester in order to read the components on the power board, once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect the problem.

Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.

I wish you the best of luck.

Regards.

Hello,

First, check the power cord. Most times, a bad power cord causes this kind of problem. But if the power cord is not the cause of the problem, then problem must be from the power cord inside the printer.

What kind of power cord does the hp scanjet 3970 need?\r\nalso the cord to conect to the computer. I have set it up on my HP laptop and it will not scan . I keep getting the message that I need to check if...


Let's compare bananas with bananas and apples with apples... if you have the unit ON with some lights and some activity going on, than the POWER CORD is just fine... you seam to refer of a communication problem (not a power problem) from the unit to the computer... normally for HP multi-function devices you have to install a USB cable and the software FIRST than connect the unit when the installer ask you to do so, FIRST UN-INSTALL all drivers & software you installed previously, reboot the computer with the unit OFF, connect the USB cable, than pop in the installation CD, go through the setup (accordingly) than when the installer ask you to connect the unit, turn it ON, than let the installer finish the configuration...

Hope this helped!

I have a F-01 fault code on my Kenmore HE2plus front load washer. model # 11047512601. Sears talked me thru the software resets and still had the F-01 error. do I need to replace the Main Control Unit?


Hi,


The F01 fault code is indicating an EEPROM error or a PUMP DRIVER error. A communication error between the Central Control Unit (CCU) and the EEPROM on board the CCU occurred.

Possible causes of an EEPROM error:
A power glitch may have caused this error. Unplug the power cord for 3 minutes then reconnect power.

Possible causes of PUMP DRIVER error:
The pump driver fails to activate. Replace the the CCU board.
Most likely the CCU board will need to be replaced.

Thank you !!

TV randomly turns itself off and on


This issue is related to the TV's main board not seeing constant A/C power to unit so the board is turning off the TV.

When the TV's main board see A/C power back to the unit, the TV will try to turn back on.

This issue could be a loose power connection for the TV or a failing part inside the TV. Do other electrical devices work when plugged into the same wall outlet?

Try the following:
1. Remove the cord from the back of the TV and reinstall it (perhaps it's loose going into the TV and was not installed correctly).
2. Try putting the cord into a different wall outlet (perhaps it's not a good outlet).
3. Try using a new power cord for the TV. (Any matching cord will work for testing)


If the above did not resolve the issue, then it could be the switch mode power supply and or the main board inside the TV. Both items are easy to change out.

I can look up the LG part number for you.

Mp530 printer, no power , no lights or beeps


This just happened to our Canon MP530, which was about 10 months old. I called Canon support and they said they'd send a new power cord to us. Then, if that didn't work, they said they'd replace the unit. Well, turns out we found a replacement power cord ourselves and tried it - amazingly, the printer now works. So if this happens to your unit, try replacing the power cord. It may just fix the problem.

Need set up cords (pictures of)


you can get the driver here

I would have to see the back of the printer for the cord types
but if it's an old printer you will probably need a parallel printer cable and the power. you can always take it to a place like radio shack and they will be able to tell you what to get. or you can post a photo

thanks for rating

Restarting while in use


Mine just started doing the same thing. I took apart the speaker power cord, but don't see anything wrong with it. I thought I saw the unit turn off/on one time when I moved the cigarette plug back and forth, but as I said the wires are fine. I have the power cord apart right now and have 12 volts hooked up to the wires directly and the unit has been sitting here for 30 minutes without resetting.
