Lg microwave fuse location

AC fuse is located just near mains cord ends up inside the top cover,it is mounted on small PCB,DC fuse is not used generally only surge protector MOV is mounted on main PCB for safety of PCB assy.

Where is the LG microwave fuse located Model LMV1630ST

Check weather the hock of the lock is broken and replace.

Since it's under warranty, I'd contact the manufacturer via the information in your owner's manual and get it fixed free.

It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the capacitor can fail and go short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

Hi,

Here is a tip that will help you to figure out what is wrong with your Microwave Oven....

This fan motor is feed from a sub mini relay on the main pcb {control board}

On page 8 of the installation manual I found, it shows that the oven can be vented to the outside. You can view it at this link:

If the link does not work, you can go to managemyhome.com and type in your model number under the "Manuals" link.

In the manual it describes three methods of venting: Room, Roof, and Wall. It also gives guidance on how to properly install the duct work.

If you have questions, please let me know. I hope this helps you.

hi..
test the high voltage capacitor,the rectifier diode or the magnetron. If all this are fine, test the control board.

The diodeand capacitors can be tested. The capacitor must be allowed dischargebefore testing, or you risk to get electrocuted, even if power is off.Capacitors can get discharged by shorting their two contacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.



All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason...
