How come my over the range microwave does not turn on at all??


Check internal fuse. If it's ok, one of the internal door switches, the high voltage circuitry, or the circuit board may have a problem. Diagnostics and repair might be quite complicates so better you take it to a repair service. You have some interesting Youtube video tutorials to repair a microwave

Replaced 20amp fuse that was blown. new fuse did not blow, but oven is still dead.


see this causes and fix it. God bless you
If your microwave oven doesn't seem to work at all, check these: Fuses Door switch Fuses Usually, when your microwave oven doesn't work it all, the internal fuse (thermal fuse) is blown. This fuse protects both you and the oven. When it blows, you need to have a qualified appliance repair technician replace it. Door switch If the fuse isn't the problem, check the door hooks and the door-release button. When these are broken, the door switch doesn't activate, so the oven can't work

The fuse probably is internal. It may be necessary to remove your OTR microwave to get access inside.

Microwave won't turn on


Hello, welcome to Fixya!

The unit not powering on is an indication that it has a power fault.

First, remove the microwave'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 microwave, it goes straight into the power supply board which then circulates the current into the unit. So if the microwave 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 microwave 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 microwave 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 within our vicinity.You might also find visible bad component without testing with a meter. 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.

I have a built-in AEG Microwave code MC166(0E?) My son unfortunately used the microwave as a timer so it was on for 30mins without anything in it. It now won't turn "on"; no light/clock...


What fuse did you change? The fuse on the wiring that leads to the microwave needs to be intact, then the fuse in the Microwave itself needs to be checked. Usually there is a plug where the microwave is plugged in, in the cabinet above the microwave, you can take another small appliance or a power tester to make sure power is available in the outlet where the microwave is plugged in. If the power is on at the outlet then you'll know that it is the microwave itself that has turned itself off for some reason. You can get manuals for these ovens at this website

Oven just went dead, no lights, no power etc. checked power source and everything works fine. Sharp Model R-9H66. looking for repair in spokane , WA..can you help?


Possibly the internal fuse. Unplug unit, remove all case screws on the back of the micro. Slide the case toward the back and remove. Look for a glass tube type fuse, simular to automotive fuses of the past. It should be located near the controls. If bad, the internal wire will be broken or burned, I have been able to find replacements at Radio Shack. Take the old one with you. If the fuse is good, I'm sorry, it's beyond my microwave knowledge level.

Microwave doesnt power up, suddenly stopped working, can it be the fuse? ow do u check if the fuse is OK?


If there is no power at all then it could be the internal power fuse has blown, there could also be other parts faulty also. I would not recommend you to check this if you are not electricallly qualified as a microwave is a very dangerous piece of equipment to tamper with, even if there is no power to it. It would be best to call a service engineer to check it over for you.

My sharp carousel II microwave doesn't seem to have power. I checked the power source and that seems fine. Is there an internal fuse?


Is it dead, meaning no display, no light when you open the door and no beeps when you press a pad on the keypad?

We have the relevant service / repair manuals for this model and have uploaded it to our site here and here to help you.

They will give you safety info, step by step help in disassembly, troubleshooting tips, and part numbers.

Most computers will open these documents automatically, but you may need the free Adobe Reader

I would suspect the 20A ceramic line fuse or the magnetron temperature fuse.

You can order parts from Encompass here or you can call them toll-free at 866-779-5835.

20A ceramic fuses are available at local appliance part stores or places like Wal-Mart and Lowe's.
