Emerson microwave 1100 watt microwave keeps running even when timer stops bought about 7 months ago


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.

Whole unit will not show power... OUtlet shows power so unit has power... Are there any fuses in the unit? Would they power down the whole unit if they were blown?


Ok....first you don't have a model or make, but yes there should be use, sometimes replacable, inside, if it blows because purhaps the unit was ran empty, it would power off the whole unit, i had a unit that would shut itself off during cooking, and never come back on for days, this was a problem witht the power supply of the circuit board, if you have no worries, purhaps bang on the side, with out denting it, and see if it comes back on, if it does don t use it.

No power to unit


What has most likely happened is that somone slowly opened the door when the unit was operating without pusing the stop/pause button first. Doin this will cause the door interlock to blow the internal fuse as it is a design safety interlock to prevent the unit from operation with the door open.

Power plug unplugged

There is a 15A fuse inside the cabinet that must be replaced. Remove the cabinet screws 4 on the side and 6 on the back then slide the cover to the rear about 1/2 inch. Lift the rear of the cover up about 15 to 20 degrees and continue to pull the cover off.

Follow the power cord from where it enters the rear of the unit. The black power wire will terminate at the fuse block. Removed the fuse and replace it with an EXACT type replacement fuse. (buy 2)

If the fuse blows again there is another problem in the unit. If it works normally there is probably nothing to be concerned about. Just make sure that before opening the door you push stop before opening the door.

To re-install the cabinet cover graso the cover from the rear... holding the back of the cover up about 15 - 20 degrees and slide it back into place. Make sure to engage the side locking tabs with the front part of the chassis before installing the mounting screws.

Thanks for using FixYa.

While in use my microwave shut off and stopped working. Could it be a fuse? If it is a fuse where would it be located.


mwaves shut off when they overheat and take a time to recover. This is a failsafe to prevent fire.make sure the unit has plenty of airflow around it and the vents are not blocked off ( hutches are notorious for overheating Mwaves) Sometimes the steam from a potato or a cup of water will overheat the sensor and cause it to shut down.

If it is a fuse the whole outer case hasd to be removed and it's usua;;y top left or right on the inner pod.

Ge model jvm 140 complete loss of power. all lights are out. there is power to receptale


Not an easy situation when it's mounted above the range,it will have to be taken down,remove the outer case and look for any and all fuses, it sounds like you have a blown fuse or if they all look good you may have a bad power supply or bad control board.
If it isn't the fuse I am not sure if it would be worth the investment to get it repaired, you may be better off to replace the whole unit?
Good Luck !

Dead microwave


There are replacable fuses inside. Taking the microwave apart requires removal of a lot of screws and the cover that can be rather bulky. make sure it's unplugged and safe before you begin. you can get replacement fuses at radio shack, ect. be sure to buy the same type and amperage. if the blow a second time there may be other issues.

You may have a blown internal fuse. While I would recommend that you take the unit to a qualified repair center, you can do a little troubleshooting on your own. You''ll need to unplug the unit, remove the outside cover and follow the line cord and you should find the fuse.

Replace it with the EXACT same value that was labeled on the original fuse. You'll probably be able to find a replacement fuse at any Radio Shack store or hardware store.

Replace the cover and plug the unit back in. Hopefully nothing was damaged and the unit will play again.

If the unit does not come back on, then there is a possibility that the unit's power supply has failed.

Please let me know if I can be of further assistance to you.

Good luck!

No light, internal fan...then no display


The light isn't a safety issue but I would think that the fan would be.

The fan is designed to remove excess heat from unit and keep it cool. Without the fan, you're now operating the unit under conditions that it wasn't designed for.

With the unit unplugged, try removing the cover and see if a fuse has blown. If so, replace it with the EXACT value of the original.

See if the unit powers up again. Try heating heating up something for 30 seconds to see if the Magnetron is still functioning.

If so, check to see if the bulb is good. Did the bulb and fan stop at the same time? If so, it might be something in common that controls both.

Don't operate it further until you have it looked at. You don't want to cause something else to fail.

Good luck!

No power


You mentioned taking the "buttons" off. That may not give you complete access to the units motherboard or power supply area. Unplug the unit and remove the outside cover. Look for a blown fuse on the motherboard or power supply. Replace it with the EXACT value of the original fuse. You can purchase a new fuse at Radio Shack or hardware store or auto parts store. Try powering up the unit again and see if it works now or whether the fuse blows again. If it blows again, the power supply may have been damaged.

Hood lights


This is a problem with the control board, which we commonly repair for $32.50. This is caused by not disconnecting the microwave from the power line when removing or installing a bulb.
