20 Most Recent Kenmore 62622 Microwave Oven - Page 6 Questions & Answers

When the oven does not heat, the problem is usually due to the magnetron failing. It the part that generates the microwaves that heat the food. It fails by shorting out causing a loud buzzing noise. The burning smell is the being magnetron overloaded due to the short. It not worth fixing since the replacement cost of a magnetron is close to the price of a new oven. Sorry.

That sounds like a problem on the invertor board. Unfortunately there is not a lot to be done on the board without a service manual and the needed experience.
Hope that helps.

It is probably a burned magnetron, sorry to tell you that a magnetron is the heart of the device (it is what produces the MICROWAVES) so it is almost the price of a new microwve oven.

You could ave it cheked could be just a fuse as well...

Good luck!

Hi,

First make sure that the top you have attached is attached properly. If yes then for sure the buzz is due to some other reason. Nothing to do with the top. It could be either of the two. Either the Magnetron has failed or the Inverter board has failed.

Thank You

This is not something that you should do yourself. There is a requirement that the unit be tested for leakage of microwaves after any service is performed. You need to have special equipment to do this. You may create a serious hazard if you dont repair it right.

Replace the keypad. Call the 1800 # in the back of your owners manual or look the # up online to order the part. If you don't want to fix it yourself you can take it to a microwave shop and have them do it. Microwaves are made cheaply enough now a days to just toss it out with the trash and get a new one.

Do the inside light and turntable come on when you try to cook?

Is it making any unusual noise or is it louder or quieter than normal?

Do you have the model number?

If everything works, but the microwave oven does not heat, this is most commonly caused by a failed magnetron. The magnetron is essentially, the heart of the oven that produces the RF energy that is used to heat your food. In order to replace a defective magnetron, you will need to consider the following:

1. You will need to uninstall the oven from over the range in order to replace the part (you will need to do this anyway, if you decide to buy a replacement oven).
2. Ensure the oven is UNPLUGGED before servicing anything inside the cabinet and remove the exterior case in order to access the magnetron. There are several websites that you can use that illustrate how the oven is assembled:
searspartsdirect.com pcappliancerepair.com appliancepartspros.com
NOTE: If you've never repaired an appliance on your own before, a microwave oven is usually not a recommended appliance to start with. Some models can be rather involved in taking apart.
3, The magnetron replacement part number for the model you have listed is 6324W1A001H. The average cost is about $42. NOTE: This model also has a thermostat that if tripped, may also cause the same symptoms. The thermostat acts as a fuse if the oven cavity overheats. The part number is 6930WRT002F. You will need to remove the thermostat from the oven and take a resistance check across the component terminals to determine if it is good or not. A low resistance reading indicates a good thermostat. An infinite reading, indicates a blown thermostat and needs to be replaced. The average replacement cost is about $5.
Review the parts illustrations at the recommended websites to see if this is something that you may be able easily take apart and reassemble.
If you have any questions, please post back and let me know. I hope you find this information helpful.
CAUTION: DO NOT operate a microwave oven with the exterior cover off. The voltage inside the High Voltage network where the magnetron is installed can exceed 3,000 volts!

Hi,

Here is a tip that will help you to figure out what is wrong with your Microwave Oven....Microwave Oven Basic Troubleshooting Tipsheatman101

It appears your magneto or power supply has failed in this instance.

For replacement parts - head on over to PartSelect.com or RepairClinic.com and enter in your full model number for a full parts listing.
I recommend both sites because ...


FixYa has no affiliation with either site - I have been using and recommending them for years - trouble free.

PartSelect has a great schematic database for locating the part on your unit and great "testimonials" for each part that often times includes HOW-TO information.
RepairClinic has pictures of each part they sell and also a great how-to and troubleshooting for basic repairs.


If your unit has never been serviced - there should still be an original service manual enclosed in plastic taped to the inside of the shell.
In the service manual are Error codes, maintenance procedures, and troubleshooting steps you can follow.


Anything too complicated or beyond your scope should be handled by a professional.

If you think you want to tackle the repair - and have gotten stuck on a step - reply to your question and I will be glad to help you out.
