Since this is under warranty, I would get the sales recipt and owner's manual and call their customer service line to find the nearest authorized servicer to repair the oven. If you take the oven apart, it will void the warranty.

Hi I am using kenwood microwave since last6 years.but now from last one year it suddenly started make sound while not in working and now it is not heating. Plz guide what to do

Time to throw it away. Microwave ovens can be dangerous if not working correctly. Micro-waves, (The actual waves themselves) can be lethal. Unless you really know what you are doing, do not under any circumstances dismantle the machine and switch it on. The cabinet of the machine is designed as a protective box and should stop random waves escaping and cooking anything else including you own insides. Generally Microwave ovens are uneconomical to repair, for the parts and labour you can buy a new one. Buy the most powerful you can. If you buy anything that is below 1000 Watts make sure it has a turn table. Remember that the more you place in a microwave oven, the longer it takes to cook. If you have a big family and you can afford it, you might like to think about a commercial oven 1600 - 1800 watts, that can cope well with large quantities well and will cook a tin of baked beans in less than a minute.

Microwave stopped working

Probably a problem with the door latch safety system. This happens every so often with our microwave, which is over 25 years old, and otherwise works perfectly.
If yours is new, it may still be under warranty. If not, there are places that specialize in fixing microwave ovens.
If it is an older, or less expensive oven, it might be time for a new one.

Okay, that loud humming sound you are hearing is coming from the unit trying to energize the magnetron. Depending on how old your oven is, it could be still under warranty (this is covered under the warranty, trust me). If it is an older oven, like 2 years or more, you can bring it to an appliance repair facility and instruct them to replace the magnetron.

I am telling you to take it to a facility because you as a consumer cannot buy a magnetron...the federal government will not allow appliance companies to sell them to you.

The buttons on the front stopped working, no display

It is still under warrantee if under a year. Contact your dealer who you bought it from-it should be repaired or replaced free of charge.

Microware shutoff after ~4 min of cooking

Return it for warranty repair or replacement. Does the blower motor operate?

Brand new panasonic nn-ct776. When using microwave only goes for about 5/6 seconds and then stops other oven cooking methods works OK.

If it stops after 7 seconds, it has a problem with the inverter.

Due to the lethal voltages used and produced in inverters, I do not recommend that an inexperienced person work on these.

Plus, since it's new (less than one year old), it would be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

Won't cook but everything works like it should

Good idea to run at half power. Good thinking. That can sometimes reveal an overheating magnetron.

Does it seem to buzz or hum louder than normal?

If so, you may have a shorted high voltage diode or a bad magnetron. If not, I only suspect the magnetron.

If it's less than one year old, it should be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

If it's within the magnetron portion of the warranty (usually 5-9 years) but out of the original full warranty (usually 1 year), then your manufacturer will cover the part cost, but not the cost to visit you or the labor charge to do the work.

We have critical safety & disassembly info (including a how-to video) at our site, linked here.

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

Whirlpool customer service is here.

Microwave runs constantly

If it's less than a year old, it's under warranty and you should call the nearest Sears store for free repairs. Quite often this is due to a bad door switch. Opening the door while cooking (without first hitting the STOP pad) is the primary cause of door switch failure. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: You can find helpful exploded view diagrams and order parts by entering your full model number here: (the 3 is correct)
