Question about LG Microwave Ovens

Open Question

I have a LG Microwave Oven Model MC-805AA. The oven cut off after 5 mins in the convection preheating mode. The MCB in the power supply tripped simultaneously. The oven heaters, grill and microwave are working. The turn table, fan and lamp are not working. There is a continuous chattering noise from the vicinity of the transformer. Appreciate help in locating the source of the problem. Are spares like PCB available? Rgds Chandran, Surat, India

If it stops after 22 seconds, that means the controller has detected a problem, usually a problem with the inverter or a bad magnetron.

Due to the lethal voltages used and produced, I do not recommend that an inexperienced person work on these.

I would recommend that you contact your nearest Panasonic-authorized servicer.

SOURCE: GE Microwave/Convection JVM 1090 oven won't reach temperature

You probably have a bad thermistor.

You can usually find helpful exploded view diagrams and order parts by entering your full model number here.

(At that site, that part is misspelled as "thermister" for your model).

There should also be a "mini-manual" hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting & testing.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Accessing some components for testing will require you to remove the oven from the wall.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

You can download GE owner's manuals and installation instructions here.

SOURCE: Have a GE Profile Microwave/Convection oven.

It may be a bad convection heating element or just a bad thermal cutout.

If it's less than one year old, it will be fully covered under warranty and you can contract GE here to have an authorized servicer come out and fix it free.

If it's out of warranty and you or someone you know wants to check it out, I'd first suggest you take a look at the "mini-manual" hidden inside the unit (behind the control panel, hidden on the left side behind the grille, or attached to the inside of the outer cover) which is very helpful when troubleshooting, & testing.

At our Web site, we have a video available showing how to remove a typical over the range control panel assembly in under 5 minutes.

Otherwise, see these files: safety disassembly

Accessing some parts may require you to pull the oven from the wall and remove the cover.

If so, the installation instructions are very handy, and it's best to have two people since the microwave can be heavy and awkward.

Hi,

There is a dead short in side the microwave... this is causing the breaker to trip...however you should also replace the breaker to the microwave, as that should trip before the MCB...unless both are tripping at the same time...

Convection Preheat doesn't reach the Chosen Oven Temperature


I would first suspect the thermister (thermistor) or a low line voltage, weak control board relay etc.

But the service manuals will show you how to safely disassemble, test and repair the unit.

We have the service manuals for this model and have uploaded them to our site here and here to help you.

You will need the
free Acrobat Reader to view or print them in case you don't have it.

The best place to order parts for this brand is Encompass (formerly Tritronics). Or you can call them toll-free at 866-779-5835.

Feel free to contact me directly (and please remind me of your full model number) for more information & help.

Oven stop working while it was preheating to 450 degrees


Chances are the oven cavity thermostat has failed.

There should be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.
