SOURCE: method of baking a cake in Microwave

I hv got a ifb microwave oven 23sci with powergrill and i have tried baking cakes half a dozen time and every time it gets burnt. The sides get baked and the central zone is unbaked. MY method is , I take a glass utensil and put the cake mixture into it and put the same into the ifb oven, then i select the microve+conventional mode (200*) and bake it for 12 minutes. Can u guide me so that my cakes have a better future hence forth.

Blown fuses


Well you certainly have done a lot of work on a microwave that is not worth the effort. When fuses blow and destroy other items ,it is time to junk it and up date. I have found that when something like what happens 9 times out of 10 it will be the magnetron or transformer either of which will be more than 1/2 the cost of a new machine.

Hello there,

When your microwave oven starts to zap, then eventually does not heat up, it means there is a problem inside the unit of the microwave. There are some parts to check inside the microwave before you can tell the exact component that is faulty and to know if replacement will do the job for you.

The three (3) main parts to be tested are the power diode, the high voltage capacitor and the magnetron.

But since all other components are working like the fan, light and clock, then it is most likely the magnetron. Here is how to test and replace the magnetron of your microwave.
HOW TO TEST THE MAGNETRON
Before you test this component, make sure your microwave is unplugged, and that you have discharged the capacitor.
There are two tests to conduct in order to determine whether or not a magnetron has become defective. If you receive results other than what are detailed below, you will have to replace your microwave's magnetron. Each test is described for you here:
TEST 1: Locate your magnetron and label each of the wires attached to it so that you know which wires are to be replaced where. Set your ohmmeter to the lowest resistance scale. Take a resistance measurement between each of the magnetron's terminals by touching each probe to one terminal each. Reverse the probes and take a second resistance measurement. Each measurement should read less than one ohm.
TEST 2: Set your ohmmeter to its highest resistance scale. Touch one of the meter's probes to a magnetron terminal. Touch the other probe to the metal magnetron housing. Take special caution to not touch the two probes together. This could result in an inaccurate reading. This test should produce a reading of infinity - indicating an open circuit.
Magnetron replacement
Have a certified and experienced appliance repair technician examine and replace your magnetron. This task is much too dangerous for the average layman to perform on his own.

Hope this helped.

Fan won't run and microwave won't heat


Hello,

Investigate these three areas if your microwave won't heat

Power Diode

A diode is an electronic component that readily passes current in one direction only and blocks the flow of current in the opposing direction. If your microwave's diode has become defective, your microwave will not heat. Test the diode to determine if this is the cause of your problem. Replace it if it is defective.

Testing a diode

NOTE: Before you test your diode, make sure your microwave is unplugged, and that you discharge the microwave's capacitor.

Whether it is shorted or open, a defective diode will most likely show some sign of defect. Defective diodes will usually emit an electrical burning smell, signifying its defectiveness. Also, it may have split in two, or it may exhibit a burned crack, or possibly even a blistered spot.

A shorted diode is indicated by a loud humming noise from the high voltage transformer, and no heat produced when a cook cycle is initiated. Whereas little or no heat produced in your microwave, with an absence of a humming noise is indicative of an open diode. In either case, the diode has to be replaced.

With your microwave unplugged, and your capacitor discharged, use extreme caution to remove the lead that leads to the capacitor. You can leave the ground connection attached. The side of the diode that goes to the ground is usually marked with a dot, stripe, or arrow. Set your ohmmeter to R x 10,000 or higher. Touch the positive meter probe to the anode and the negative meter probe to the cathode to measure the resistance across the diode terminals. Remember that the cathode is on the side that goes to the ground, which is often marked by a dot, stripe, or an arrow.

A normal diode, that is a non-defective diode, will read anywhere from 50,000 to 200,000 ohms. Differences in microwave make and model account for this large range in resistance readings.

Reverse the meter probes and measure resistance while touching the positive probe to the cathode and the negative probe to the anode. Reversing the probes like this should result in a reading of infinity. Unless a bleeder resistor is present. The presence of a bleeder resistor would produce a reading of the value of the resistor.

High Voltage Capacitor

A capacitor is an electrical device which stores electricity. A defective capacitor may be why your microwave is not heating. The capacitor will have to be tested to determine if this is the cause of your problem. A defective capacitor will have to be replaced before your microwave will work again. Make sure you discharge the capacitor before you test it, though.

Magnetron

A defective magnetron is the third possible cause of why your microwave is not heating. Test your microwave's magnetron. Replace it if it is defective.

Hi,

the fault is from the magnetron of the microwave. The magnetron is gradually becoming defective, that's why you are hearing the buzzing sound. As a matter of fact, the magnetron is the one making that noise. Sooner or later, the microwave won't heat any longer when the case of the microwave gets worse.

First, you need to test the magnetron.
