    When you hit Start to cook, do the inside light and turntable come on?

    Any unusual noises?

    Is it louder or quieter than usual?

SOURCE: Belling BEL-CJ/SS25 microwave

My Belling BEL-CJ/SS25 Microwave / oven / grill has recently developed a problem. Every time I close the door the turntable starts rotating, even when I'm not using it. It doesn't make a noise, and doesn't seem to be going into any cooking setting, and the light doesn't come on, but it turns until I open the door, when the light comes on and the turntable stops turning. This has only recently started happening, and nothing else seems to be wrong with it, Is this safe or should I get rid of it and buy a new one. The guarantee has expired so repair may be cost prohibitive.

Hello,

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.

Testing a magnetron

NOTE: 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 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.

If you cannot perform the above task yourself, ask a family or friend that has the ability to assist you or 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.

Read the tips on the below links on how to replace your microwave oven's diode and how to discharge the capacitor.

I hope the above is helpful.

Regards.

Microwave operates but does not heat


The High Power Transformer (Magnetron) fuse is wrong. Replace it. It will work perfect... The fuse is always hidden in a plastic case fixed at the bottom of the microwave near the big capacitor... My email: neo@intnet.mu

Turning motor failing


It could be the motor failing (gears jamming due to internal damage or bad grease, perhaps) or the turntable coupler or support may have gotten warped due to heat. One test is to gently but firmly grab the coupler or turntable support and try to turn the motor. A good motor will offer resistance and "whirr" as you turn it. A bad motor will grind or click, etc. I would call Westpoint (see your owner's manual) and they can tell you if the parts are available and what they'd cost. Other listings seems to indicate this is an 800W microwave. And I would bet that parts may not be easily available. The turntable can usually be replaced from the bottom without taking the wrapper off. Once you've found out about parts availability, feel free to drop by my site (see my profile) to get my microwave safety and disassembly texts.
