No heat our microwave does not heat. Everything looks good, it goes on and times....but no heat. please advise. thank you.

If everything works, but no heat sounds like the magnetron circuit has failed. Since it is brand new, just take it back to the store and complaint that it does not work, and ask for a refund or replacement oven.

Hello, installing is quite straight forward if you know what youre doing. BUT, be very careful of the voltage in the capacitor even when its off,it is lethal! When you change the magnetron it is advisable that you also change the diodes. Again make sure that the capacitor is fully discharged, by switching the microwave off, unplugging it, and discharging the capacitor with an insulated screwdriver, it will be noisy. Next unsolder the old diodes and fit the new ones(check their polarity). Replace the magnetron and when all looks good,switch it on. If it works, good, if not there could be a power supply problem. 9 times out of 10 its the magnetron. Good luck.

Hi,

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

Microwave Oven Basic Troubleshooting Tips

heatman101

this model has been discontinued,replaced with model kcms1555sss,probably cant get parts if needed.sorry cant be of more help

Check the fuse in the bottom of the oven ... near where the power cord enters.

time for a new one. the microwave unit is dead, no the oven. the microwave unit is the heart of the oven. so, if that goes, everything else goes.

this is something you should probably call a repair technician for, due to the danger of the componentry.

Usually in ther case of this problem, even a technician will advise you to replace the unit, in the minds of cost effectiveness and safety...

The problem you are having is that the magnetron that does the heating is shorting out and it needs to be replaced before it damages the inside covering of the microwave. www.mwoparts.com is a good source for magnetrons or other similar sites. To replace is easy enough. Taking the cover off with the power off, you will find it behind and on the top right side of the control panel. It is held in place normally with just 4 screws and two wires with terminals attached to it. So removing and replacing is pretty straightforward. Just be sure all the power is off until you have everything back in place. Good luck.

The magnatron in your oven has gone out and will need replaced!( This is the device that heats up your food) If everything is working and your food is not getting hot 99.9 percent of the time its the Magnatron or its fuse! The loud humming is also a big clue the MAGNATRON has gone bad!
