My Lamona HJA7020 microwave has a lock and timer symbol on the screen and I can't get rid of them. Tried holding stop/cancel button down for 3 secs as it says in the manual you should do to cancel child lock but it's not working. Any ideas anyone ?

ask GE what might be wrong we only know stuff we have seen sorry

There is a method described in this article that can be used even if you can't find a manual.

Quoting: "To find an approximation of your machine's wattage, fill a microwave-safe liquid measuring cup with 1 cup cold water. Microwave on High and keep an eye on it, noting how long it takes for the water to come to a boil:

• 1 1/2 minutes: 1,200 watts
• 2 minutes: 1,000 watts
• 2 1/2 minutes: 800 watts
• 3 minutes: 700 watts
• 4 minutes: 600 watts

Lock-out Function for Children
Lock: In waiting state, press " Stop/Clear" for 3 seconds, there will be a long beep if the
time has been set, otherwise, the LED will display "Left brack equal equal sign right bracket "



Lock quitting: In locked state, press " Stop/Clear" for 3 seconds, there will be a long "beep" denoting that the lock is released.


If necessary, call the Lamona Service Line on 0845 00 60 00 and ask for assistance.

I realize this is 2 years old, but all you do is hold down stop/cancel for 3 seconds. That also turns on child lock.

Hey JT Tai, I appreciate your post!
The symbol at the top left hand side of your display could be child lock symbol or vent symbol. If it is the child lock you should be able to press and hold the stop/cancel button down for 3 seconds to release the child lock.

If the light is on for the vent I would seek assistance from a professional for proper diagnosis and repair to be completed on your microwave. I hope this is helpful. -Matt

Look for some button that has some teeny-tiny print beneath it that says something like "Lock - hold for 3 sec". Press and hold that button for 3 or more seconds, and your microwave should function normally.

FIRST REMOVE THE POWER CORD FROM POWER SOCKET AND OPEN THE COVER OF MICROWAVE OVEN REPLACE THE BULB

Many microwave CHILD LOCK features are activated / disabled by repeatedly pressing one of the function buttons or by holding it down for about 5 seconds.

Try pressing the STOP / CANCEL button 3 or 4 times in a row to see if you can the CHILD LOCK off.

If that doesn't work, also try holding down that button down for 5 seconds.

Try these same two procedures on some of the other buttons as well like the TIMER button, or the START button, or the CLOCK button.

Your best bet however would be to include the brand and model number with your question next time and then we will be able to locate the exact instructions for you.

I hope this was helpful.

Good luck and take care.

on VIP27 (crisp series), hold only Cancel/Stop for about 3-5 seconds.

Pressing "timer/clock" button 4 times turns on and off demo mode.
