You will have to check the fuse inside the unit, and take the cover off to get at it. Chances are if it's totally dead, it's the fuse. If not, it could be a problem with the power supply, and the unit will have to be systematicaly troubleshot. If you go to the following website and enter your model number, you may get diagrams and parts lists to help you troubleshoot the unit:

If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

Sharp R-1870F Microwave Won't turn on


Could be just a fuse but probably the diode pack or magnetron.

Won't run


see this causes and fix it. God bless you
No Lights or Power, Unit seems Dead First check is the main fuse of the unit. On countertop units, you will need to take the shell off. The fuse will be close to where the cord comes through into the unit. OTR units, this main fuse is usually behind the control panel or possibly behind the vent. Usually the fuse is obvious if blown, otherwise test with an OHM meter, if open, replace fuse.
Some brands will also have a thermal cut-off fuse in the incoming voltage line to the control board. Older Maytags and Samsungs have this fuse in it. This thermostat looking fuse is usually above the oven cavity somewhere under the outside shell. Sometimes you can get to it through the vent of OTR models. Test with an OHM meter, replace if open.
Test the switchs door see diagram

Touchpad dead If you have a stuck key or non-responsive key, most of the time you will have to replace the keypad for this microwave oven repair. If your keypad is connected to your control board by a flat ribbon wire, try disconnecting it and clean the silver contacts with an ordinary pencil eraser. After cleaning, plug it back in and try it. If it doesn't fix it, replace the keypad unit. Some units actually have keypad tests to confirm your diagnosis of a bad key.
If your keypad and control is the same unit, replace that unit. Another note, unlike stove/oven keypads and controls, most microwaves do not have error codes or tests to distinguish whether it is truely the keypad or control. Most of the time, it is the keypad that needs replacing, but a small percentage of the time it can be the control. Check the tech sheet if they can point you to the right part.

No lights - Acts Like It Has No Power At All


see the diagram and pictorial and proceed with common sense:
1) test the fuse for open or band contact with VOM,see the diagram attached how to do it
2)check the switch door hook or door release button,when they are broken they do not touch the switch, and will NOT start. test for open
see the diagram

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.

Frigidaire microwave not heating over the range


Hello

Try to cook something simple such as microwave popcorn. If the unit does not light up or turn on, check the outlet with another appliance to make sure the outlet is functioning correctly.


Check the fuses or circuit breakers in you house. If the outlet does not work after testing it with another appliance, try to plug the microwave in a different outlet.


Check the hinges and door hooks to make sure the door is closing properly. Look to see whether a small piece of food is clinging to the door, preventing it from closing all the way. Check the release mechanism and the rotating plate to make sure they can move freely as well.


Plug in the microwave and start it a the bag of microwave popcorn inside. If the lights go on but it is not producing heat, listen and try to hear whether the unit sounds the way it usually does. If it does not, there might be problems with the circuit board. This will need to be repaired by a certified Frigidaire professional.


Check the display that shows the time and power. If the display is flickering but it does not alter the operation of the microwave, it is not a problem. If, however, the lights flicker and your food is not heating, there may be a problem in the microwave cabinet.


Listen for buzzing sounds. If there is a buzzing sound and no heat is being produced, you may have to get a new magnetron, power diode, or high-voltage capacitor. These can be purchased from a Frigidaire retailer.


Look at the handle on the door. The most common complaint about all models of the Frigidaire microwave, according to Consumeraffairs.com, was cracked or broken door handles. Frigidaire will replace faulty handles while the oven is under warranty. In many cases, they will replace the handle even after the warranty expires for a "reasonable" amount of time.
