Question about GE JVM1850 1000 Watts Microwave Oven

1 Answer

Humming sound My microwave suddenly started making an intermittent humming sound that stops if you open the door. When the oven is making that noise, it is heating the interior of the oven. The glass plate gets hot to the touch. Any ideas?

    I have a Samsung microwave oven (model SMH1816S/XAC). I went to use the oven and noticed that there as a lot of heat coming from it (typically it's very cool in the oven). The glass plate and the walls in the oven were quite hot. The power was shut-off and I can not revive it by unplugging and replugging it back in.

    I assume that it has over-heated and tripped it's fuse or it is waiting for the temperature to drop in the oven before it will allow itself to be turned back on.

    My question is: Why was it so hot when it was not in use? It has never done that before and that worries me. Does this sound like something that can be easily fixed?
    Thanks

    I have a Samsung Microwave (Model: SMH1816S/XAC). New within a year and a half.

    I went to use it today and noticed a lot of heat coming from the oven. When I opened the door I noticed the glass plate and the walls of the over were quite hot. The power had been automatically shut off. The odd part was that the oven had not been used before hand and that worries me.

    I assume the oven has over-heated and automatically shut itself off. My Question is: Why would the oven have overheated like this it hadn't been turned on?

    Thanks for your help.

In my professional opinion, it sounds like you have a shorted relay or other defective component on your control circuit board, which is actually made by Samsung. We regularly repair these control panel assemblies nationwide for $32.50, so the problem can certainly be fixed economically. Looking at typical microwave wiring shows it has to be the cooking relay or a device that drives that relay. Since it stops when you open the door, we can say the door switches are certainly doing their job.

Magnatron suddenly making more noise. Much louder


Often over the years the Transformer laminations can loosen, from the on/off rising and collapsing magnetic fields, and then they sorta hum louder. I suspect this is what is going on. Shouldn't be too much of a worry.. keep an eye on it tho.

If it is working but not heating, then 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 discharge before testing, or you risk to get electrocuted, evenif 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.

Regarding parts, contact the seller here to purchase parts.

You can also order from MicrowaveSvc , they also provide parts.

There should 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.

Can you scan and e-mail or photocopy & fax the "schematic diagram" portion of the mini-manual to me?

Feel free to contact me directly for more information & help.
