Since you posted a new message instead of replying back to the existing thread, I have no real sense of context as to what we are talking about.

So I would have to point you back to Delonghi to ask them where to buy parts, then ask the parts people of the board is available. If not, then you'll you'll need to find a technician who repairs boards or replace the oven.

LG ldg3016st has no power on main control panel

Did you have any power surges in the house? Any thunder storms?? even if you are not using a microwave, but it is plugged in , you see the clock?? That means it is getting power and running the clock so while you may not be cooking in it, it is actually using power to run the clock functions. So, if there was a power surge, it damages a part on the main board called the Low voltage transformer. It takes the 120 volts from the wall and drops it down to the voltages the board needs to operate, sometimes 5,12 24 or maybe 30 volts. If the primnary winding gets damaged from a surge of some sort. it will no longer light up if that small transformer was damaged. That can happen without even blowing the fuse as the small wires in the transformer were never meant to carry the 15 or 20 amps the fuse is rated at. So the transformer goes bad and the unit is dead but no blown fuse. Have to check the primary winding of the low volt transformer to see if it has continuity. If not, will need new main circuit board. Sorry But $$$$$

Inspect foil side of HV board for burned tracks toward lower side of board. If burned, check HV capacitors (High Voltage Capacitor Test Procedure) and HV transformers (High Voltage Transformer Test) for a short. Otherwise test other components as outlined above.
Solution: Replace defective components as necessary. If applicable, repair foil trace on HV board.
Hope that helps.........

Did you check the fuse ? If that is ok then normally what goes first is a standby transformer on the front board itself. There is thermal fuse located inside the transformer that goes open circuit. A fairly easy and quick fix.

No power everything was fine then nothing when i got home is there any fuses to check in the microwave

There is a fuse under the cover, as well as a couple of safety thermostats that can cause a dead oven. It may also be that the power transformer for the control circuit board has failed. I've seen several Sharp ovens where the transformer died because of power surges. This would cause no display and no functions even though the oven has power. Also, did you make sure the outlet your oven is plugged into has power? If it's a GFI outlet it may need to be reset, or a circuit breaker in your electric service panel may have tripped.

Hope this helps, and thanks for using Fixya!

I have a Delongi Microwave combi and need to locate the lamp, the model is AC930AMQ, so far I cannot see the lamp anywhere and need to replace it. If it is internal I have no prblem with that as I am an...

I removed the outer case by three posidrive screws and two security screws. The lamp is located in a downward position on the left hand side looking from the back. A normal 25watt 300c ses bulb is suitable so no need to buy original if you don't want to. Take care before removing cover by unplugging the unit and only work on the lamp area as there is high voltage present charged in the capacitors !

Where is the 10 amp fuse on my delonghi micro/combo/grill please

Hi, I take it that this is a combi microwave? Some of these have settings on the front to microwave/grill/etc... so make sure its on the right one first!!
If you have selected the correct one then the m/wave does not work it could be several things!
Microwaves run to earth and need diodes to do this if these break down it will not m/wave! It could also be a internal fuse? ( but very unlikley if everything else works) Then you have the Mag or transformer which could be down to! M/waves run on a high power side and a low power side. The low power will not hurt you to much but the high power side will. My advice to uou is not to touch as it could be fatal as these things carry a high charge even when they are unplugged!

If there is continuity between the two terminals of the high voltage capacitor, then it is shorted and will need to be replaced.

When the cap shorts, it will blow the fuse, too.

Delonghi AC930AMQ Microwave, Interior Light Bulb

The bulb is usually run by one of the door switches, but in some cases they are run by a relay on the board.

I would suggest you look over our files on safety & door switches here:
