Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if the switch contact are not good then it will not trigger the processor to switch on the waveguides. If the lights or fan work without any display or action of program being triggered to start then it can be a possible fault on the main board or the processor. Sometimes insect secretion can short the board and display panel and so the processor can work in such an erratic manner. If so clean, solder and reset the board. Now identify the parts by clicking this link: http://www.espares.co.uk/advice/microwave/a/5/141/identifying-microwave-parts.html

If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron. Check this link to know how a microwave works:

http://www.espares.co.uk/advice/microwave/a/5/1443/how-a-microwave-oven-works.html

So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off. Check the wave guide covers, if food had deposited
then it must be checked or replaced. See link:
http://www.espares.co.uk/advice/microwave/a/5/1146/how-to-replace-a-microwave-guide-cover.html

Now keeping clear of the microwave, switch on; use a cup of water inside to test.
If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.
If there is heating without any issues, you can use the microwave safely

HELLO.

The first wayout is to consider WARRANTY.If the microwave is under warranty return it to the point of purchase to enjoy warranty right.But if the microwave is not under warranty another wayout is needed.

Below is the solution on how to make our microwave heat food.

1 Remove oven racks and place them in soapy water to soak.

2 Preheat oven to 200 degrees.

  • 3 Turn the oven off and spray the inside with oven cleaner.

  • 4 Allow to sit for 10 minutes.

  • 5 Wipe the cleaner and dirt away with a damp sponge, rinsing frequently.

  • 6 Dry with a soft cloth.

  • Thanks.

    Rival rgst902 microwave. Door won't open.


    verify that door is perfectly aligned with frame edge , sometimes in busy kitchens the door gets bumped and it no longer aligns with frame , if one forces it shut the mild spring that pops it open cant overcome the friction of frame hitting and it wont open requiring one to "HELP" it to open while holding down open button , look at latch carefully when open to see if any parts look bent or "not quite right "
