follow this charter troubleshooting and fix it. God bless you
Inspect the power cordUnplug
the power cord and check for voltage at the outlet. Also inspect for
damage, shorts, or burn marks that can be a possible safety hazard.
Bad door switchIf your
microwave does not work at all and you know everything is plugged in
properly and the outlet is functioning, then also check the door hooks
and the door release button. Using a volt-ohm meter on RX1, check your
terminals. When your microwave door is closed you should have a reading
of zero. Once the door is open the reading should change to infinity. If
these readings do not match up, replacement of the door switch is
necessary.
Blown fusesTo determine
if your fuse has blown out, which may attribute to your microwave not
running, you need to pull the fuse out using a pair of fuse pullers. Lay
it down and using a volt-ohm meter on RX1, check both ends of the fuse
in question. If you do not get a reading of zero, then you will need to
replace the fuse.
Bad fan motorLocate the
fan and remove the leads. Again using the volt-ohm meter on RX1, check
the terminals. If an infinity reading is displayed, it means that the
fan has gone bad and requires replacement.
I found one of these on the curb. Took it home, and it was completely dead as you described. Took it apart, and there's a thermal fuse mounted above the convection fan that had blown. According to the data sheet, the fuse blows at 240C, but even if it never sees that temperature it will still fail eventually if exposed to high enough temperatures. The fuse is mounted against the chamber where it will get hot, so basically these ovens are designed to have a finite lifetime.
Anyway, long story short, you can buy replacement fuses online for a few bucks. It's a SEFUSE SF240E. Or just bypass the fuse. Keep in mind that the fuse is a safety feature that will kill the oven if it overheats, so keep that in mind if you decide to bypass it.
Hi, if the the toaster already quit, that could be probably the fuse that got busted on your Oven. you can check with any local technician in your area to see on how you can get it changed.
Thank you for using Fixya.
in 90 % of my microwave is damaged the magnetron, on the electronic plate you have 2 fuses and dawn under the rear fan you have another fuse(glass fuse) in a plastic cover.
My KA KCO100508B blew its thermal fuse after 3 years. I found a replacemnt close to 206 centigrade for $2.60 at Appliance Parts Warehouse near my home in Smyrna, GA. Know what to ask for when you enter APW. They don't like selling potential fire hazards to novice repairpersons!
You need to go to your local Harbor Freight Tools and pick up a security tool kit for $9.99 so you'll get the bits required to remove the special screws. You need to remove all the screws around the outer edge of rear and then pull the white rubber plugs out of feet and remove the screws from feet. Then the entire cover lifts off of unit. That exposes where the power cord enters the back of unit. You'll see a smaller black wire leaving that area going over to the timer knob. Before the wire gets to the timer knob, there is a sleve covering the wire. If you'll cut the zip tie holding all the wires together, you can slide the sleve (mine is red) backwards toward where the power wire comes into unit. That will expose the inline fuse that is blown. You will need to call Delonghi to order the wire. It is pressure fitted on. You should be able to pull the connectors lose by hand on each end. Simple fix!!
