Hi. The DEFY DMO367 MWM 2030W microwave oven's magnetron needs renewal. I have got as far as removing the right-hand mounting hex/star screw and the top domed star screw that secures the light cover. The 700W magnetron is half loose on R/H side, but left still stuck. I suspect the mag left may have another screw hidden under the light cover, the problem being a very tight star domed screw under the magnetron holding light cover, which won't come loose. Previous covers have always just unhooked from bottom once top is loosened. Anybody worked on this before? Thanks, Clive.
It is cheaper to just replace the oven.

Testimonial: "Thanks. I'll compare the cost of a magnetron & diode (About R800) against my almost new Micro (R1400). As per my target question re removing the stuck screw, another forum suggested 'shocking' it loose with a chisel-tap or heatgun."
PS- I inspected under the lightbox using a webcam as a 'scope'. There is a screw holding the left wing.
What currency "R" India?
ZAR. South African Rand. Bought new magnetron and HV diode from electrical supplier for R350 both. Micro working again.

SOURCE: Paint damaged in side microwave oven
1) How is the cavity damaged? Is it just peeling paint, or is it rust? If it's rust then the microwave could be dangerous.
2) The antenna cap usually has a small hole in the centre, but if there are any other holes in it the magnetron itself could be damaged, and holes caused by the magnetrin arcing.

HI,
this will require the skilled hands of a qualified tech. the damaged part here is the Magnetron assembly. this is a very sensitive part that creates radiation and the heating process as well. you will need to replace this device asap if possible...
thank u

If you can get to the top screws without pulling the unit down then you can do the job. Sometimes though it goes back together and alignment is simpler if it is on a table and the cabinet is off. I have successfully done it both ways but neither is what I consider easy.

The sensor you detail has no polarity. It can go "either way"
For goodness sake be careful, I don't want to scare you but more servicemen, & would-be-servicemen die each year "trying" to service Microwave ovens.
They are lethel, or rather the Main Capacitor is, it stores enough Joules to kill someone 10 times over.. Always ensure it is discharged to earth before working on anything.
Be careful.
