This is probably due to a defective or possibly loose magnetron.

If yours has loose mounting nuts / bolts or the wire mesh RF gasket was not installed or got pinched, that can also cause
this RF leakage interference inside the oven.

It may also need a new high-voltage diode and stirrer, and the cavity may be affected.

GE had a campaign (but not a recall!) covering several models.

I pulled the top and sides (one piece) of the microwave. Near where the 110 volt line goes into the unit is a standard fuse ( 18 amp). I used an ohmeter on ther fuse and determined that it was not working and replaced it. Problem solved - unless it blows again.

SOURCE: my microwave says "child" and won't play anymore

Not sure of the TT series models but for the NN series models the procedure is as follows:-

If "Child" is displayed in the display window, then the child safety lock is on.

To remove the child safey lock, press the "Stop/Reset" button 3 times in fairly short succession (less than 3 seconds). The time of day or just the Colon sign (:) is then displayed

If you later want to apply the Child safety lock, then, when the time of day (or colon sign) is displayed, press "Start" 3 times (again in short succession).

Hope this helps

Doug

SOURCE: Microwave won't heat anything

Yeah, it's time to invest in a new oven. The magnetron tube in yours most likely just finally wore out. It's the source of the microwaves, and like any tube it gets weaker with age and finally just quits altogether. It would cost more for a new magnetron than it would for a new oven these days.

Powers off immediately after starting


My immediate reaction would be to cut your losses and buy a new unit as sooner or later you will run into a part that is no longer available.

My NN-T994SFR Panasonic Microwave shuts off after 1 second.


My unit shuts off after about 2 seconds. It seems like it tries to go, but it sounds like it stops working and then 1 or 2 more seconds run off and it shuts down. Then you hit start again and it lights up inside and then shuts down. It's only about 2 or 3 years old.Any solutions?

GE microwave won't turn off


Just checked the GE website. Had the same problem with my 5 year old microwave. GE website says to close and open the door quickly three times. First time I did this it didn't work. Second time I closed the door with some significant force and reopened it more quickly. Worked. Unplugged the microwave, plugged it back in, still fine.

Microwave turns itself off after a couple of seconds


Q - My microwave seems to shut off every once in a while, what might be wrong?
A - Make sure you hear the fan is still operating in your microwave. Next is to make sure the air intake grill on your microwave is not plugged up with air borne dust and dirt.
Q - The fan in my microwave oven is not running will this hurt my microwave?
A - YES, the fan cools the magnetron and electronics, take the microwave in for service, most fans are not too expensive to replace.
Q - My microwave blows the fuse inside itself as soon as I push the start button.
A - Usually a shorted high voltage capacitor...see components section.
