Microwave power level

It does not work that way. The microwave OVEN generates (electromagnetic) microwaves that are absorbed by the molecules of the food in the oven, the container and the air.
The absorption rate depends on the molecular composition. After enough microwave energy is absorbed the overall temperature increases and the food is warmed, heated or cooked. If your mixture is inhomogeneous some parts absorb more energy while other absorb less and you can have hot spots.

The power level by itself won't give you an indication of the temperature because you need to know the time that the power has been applied. In simple terms Energy =time*power. The temperature reached is somewhat proportional to the energy, that makes it dependent on the time and the power.

Check the "power" level setting.

Most microwaves allow adjusting the power level from 1 to 10 (or 10 to 100 on some models). 10 (or 100) is the highest/quickest setting.

I can check mine by entering a time...then before pushing "start"....push the "power" button....and change the level if I want.

That shows triac semiconductor is working fine, the problem is the magnetron, "heats food" cracked high voltage diode or a shorted high voltage capacitor.

If the microwave is turned on and you can hear the fan working when you set the time you should make sure of those things:1. You have selected the proper programme. Some microwaves have a control desiged to use the programs on the buttons. if you want to you the buttons to set time you should select "microwave" or a similar button and then press the power level like "1", "2" or "80", "100" (being percentage) and then press the buttons for timing.2. If you have used it for a while and it suddenly stopped heating the food, than it could be that your magnetron (a spare part) has burned out. Have a specialist replace it, or just get a new microwave, the price difference won't be that great for standard issue microwaves.

There is a solid state switching device called a triac "electronic voltage controller" that has malfunctioned, it controls the power level settings when making power selection, It will need to be replaced to correct the problem. This repair should be done by a qualified technician because dangerous high voltages are present.

• Press "Time Cook" or "Micro Cook."
  
  
• Enter cooking time.
  
  
• Press "Power Level".
  
  
• Select a desired power level 1-10 (default is 10).
  
  
• Press "Start"

it sounds like the magnatron if it dosen't heat the food throw away job :( hope this helps
