Replace magentron in Kenmore 79202 microwave

10 posts in this topic

My wife ran the microwave empty and it looks like the magentron has a burned spot on the side of it now.  I can get the part for $60 but Im not sure how to go about discharging the capacitors to swap the parts.

Microwave ovens are not a job for a grasshopper in my honest opinion.

The model is 721.79202010.  I did talk to a friend of a friend who is an appliance repairman about this.  If I can access the magnetron, which I can, then I need to verify the charge is out of the capacitors (I have an amp meter for that) then just swap the part (which is 5 easily accessible screws and 1 connector).  Is there really that much more to it?

... 721.79202010

Kenmore M/W made by LG

It looks like the high-voltage Capacitor as a built-in bleeder resistor.

It should discharge itself in a few hours (or less).

But to be sure, short across the capacitor leads with a screwdriver rather than your fingers :woot:

The magnetron is all swapped out and the microwave seems fine.  Thanks all.  Is there anything hazardous in the old magentron to keep me from breaking it into its recyclable components?

Nothing hazardous at all, only thing of interest and use are the two powerful magnets.
