Model R-1450 Microwave Oven

Setting the Child Protection Lock

You can lock your microwave oven so it can't be used by unsupervised

children.

1 Press the My Choice Button and the 5 button at the same time for

3 seconds.

The display shows : CHILD LOCK ON.

2 The display returns to the time of day.

At this point, the microwave oven cannot be used until it is unlocked. To
unlock it, repeat steps 1-2 above.

Most microwave ovens are like computers, they lock up and ocassionally need to be "re-booted", or re-powered. 1. Simply unplug the oven, then wait about 10 seconds, plug it back, and check to see if has unlocked itself. If not, continually press the clear or reset button. If that doesn't help, you'll have to get the model number and manufacturer from the label inside the microwave oven.

That model had 900 watts of microwave power output, and the convection outpout was 1450 watts.

Here you go.

The Child Lock shuts down the control panel pads to prevent
unintended use of the microwave oven.
When the control is locked, only the Vent Fan and Light pads will
function.
To Lock/Unlock Control: The microwave oven and Timer must
be off. Touch and hold START for 5 seconds until 2 tones sound
and a lock icon appears on the display. Repeat to unlock and
remove the lock icon from display.

either your hi voltage capacitor,hv diode or the magnetron tube are weak

my ge microwave oven model HVM1540LMICS reads "LOCKED", how do I unlock?

"Locke" meaning the door? or locked meaning the buttons don't work? If it is the buttons then you have the child lock on. Push and hold the "Start" button for 4 to 5 seconds, and it will unlock.

Power level 1 = 10%, 2 = 20%, 9 = 90%, etc.

So 1000/1450 ~ .69, so use power level 7.
