Lg microwave fuse location

Fuses are normally internal on Microwaves and opening the cabinet exposes dangerous voltages, even when disconnected.

The fuses used are 'Ceramic' and look like this.

Where is the fuse on mikeawave model 721.8004970 it not on botton of unit

I am guessing that this is a LG microwave. The fuse should be on the top of the fan housing. It is part number 50FZZA time delay fuse that should be available in any hardware/automobile store. 72180049700&ModelNum=72180049700">Fuse Time Delay

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)))

Wont heat

Hi, there are three issues that will cause a no heat situation in a microwave. these issue are a failed Magnetron, busted cut-off fuse and, failed diode.

I recommend checking all these area that are located inside the microwave for faults.

The most common issue will be a failed Magnetron.

The diode and, fuse will be located on the noise filter assembly.

LG ms-304ez microwave

I would suspect the fuse or the thermostat.

The fuse should be located on a filter board near the back of the unit where the cord comes in.

The thermostat should be located on the left rear corner of the chassis above the cooking cavity.

We have two service manuals for this type of 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 already.

Since these are not exactly the same models as yours, the part number for the thermostat may not be the same. You should verify them with the distributor.
