Goldstar MV-1526W Microwave Oven caught fire over the control panel. The fire was on the connection to the LG Magnetron 2M214 can it be fixed?

take it to a repair shop for a proper diagnosis but generally anything other than a fuse , it will be cheaper to get a new unit

Why does my microwave stop working and flash F-9

Since this an LG microwave, an F9 error when the inverter module fails. Unfortunately, other parts could cause the inverter to read as a failure. A bad magnetron, relay 2 or door switches or the connections between the various parts could be bad. Since the microwave is starting, the switches are the least likely culprit. However, it's hard to determine if the inverter or the magnetron is bad without replacing one part. Then the other if the first repair doesn't solve the problem.

I hope this helps.

How do i test if the magnatron is not working on my lg ms3448xrk microwave. i am an electrician

Unplug microwave, remove top, set meter to ohms, unhook one wire from the magnetron, low resistance reading means it is good, open reading or infinity means it is bad. For the final test, put one test lead where the wire was unhooked, now put the other test probe on the magnetron chassis, any resistance reading indicates leakage and the magnetron is bad.

Microwave model MV-1510M is not heating, also sounds louder. Everything else is working, fan, lights, turntable etc..

If everything is working normally, except for heating, the likely cause is the magnetron.  Microwaves can be dangerous to work on, as the site below points out.  If you have an ohmmeter, it is possible to check the magnetron, but be certain to follow the precautions outlined at the webpage:

The magnetron (the part that heats the food) may be bad or the circuitry to the magnetron may have burned out. Basically my advice is that if you have no electrical expertise, it isn't worth fixing. The magnetron if bad, costs almost as much as a new microwave. If you open it up (make sure it has been unplugged for a few hours and don't seen any obvious burnt parts (including a fuse and the diodes), then most likely the magnetron is done and a new microwave is the way to go.

Let me know how this works out for you.

Does not heat up

HI. in most cases, this will lead to a failed Heating device(magnetron tube).It would be wise to check the Magnetron cutoff fuse to be sure of its integrity. if the fuse is blown, simply replace it. if the fuse continues to show continuity, replace the magnetron.

(((The fuse is located inside the unit along side the magnetron)))

Erm microwave lg mc804a has started to overheat and shutdown cleaned all the vents from dust etc now its got 2 fans 1 near the main transformer and the other at the backend on the microwave the 1 at the...

The cooling fans must be working and vents clear to ensure good cooling air flow.

Otherwise, the magnetron will overheat and it will shut down.

If this continues too long, the magnetron will be damaged.

Microwave will not heat food

Found this under Maytag instead of LG, but will be happy to help.

Generally, the most common causes of a failure to heat are:

- bad door switches or door switch mounts
- loose connection at the magnetron
- problem or loose connection on the control unit circuit board
- bad magnetron or other high voltage part

If you or a friend decide to look into it, we have critical safety information, info on door switch diagnosis and replacement, and disassembly information at our site, and our link is at our listing here on FixYa:
