Control panel keeps asking to reset the clock

Usually one presses the control panel Off/Reset button, presses the clock button, enters the time (eg. 710 for 7:10) and presses the clock button again.

you probley need a magnatron..also check your door saftey switched

Unplug for a minute and set the clock as you normally would using the clock button on the control panel

Hi Ben,
This has got to be an intermittent power to the control PCB problem. The control board asking to set the clock means that the CPU has been reset by losing power. First, make sure that the problem is not the outlet by plugging in a small lamp or digital clock to see if it works intermittently or resets. Leave it plugged in for at least 24 hours.
(If using a lamp, put in a small 20 watt light bulb or CFL).
It could also be a bad connection to or at the fuse holder in the microwave oven. If all of the wiring and connections look good, it's most likely a bad connection on the control PCB probably around the transformer on the board. Be careful.......

1. Defective controller or its power supply.
2. Broken display panel.
3. Oven needs to be reset (pull plug for a minute or two to reset).
God bless you

I would replace the control panel if it is ecconomical to do so. Call an authorised LG repair shop for a quote.
Hope that helps.

Try going to the breaker box and shutting off the power to the microwave for 10 minutes. After 10 minutes, turn back on and set the clock. This fixed my clock and turntable both. Apparently turning off the power resets the software in the clock.

The clue is that you have to reset the clock. You are losing power somehow. the Main Board thinks it is being unplugged and it resets the clock and you have to start all over. The fact that after so many times it will finally work tells me that whatever bad connection you have is finally getting hot enough to expand and make a good enough connection to keep working. Intermittant connections are the worse to find. A lot of trial and error to find the problem. can be bad fuse and fuse holder ( in the unit), bad outlet, loose wire at circuit breaker, loose wire at outlet. Even a loose breaker where it snaps onto the buss bar in the Breaker Box. Etc, it an really drive you nuts trying to find it. Try the unit in a totally different area making sure it is on a compleately different circuit breaker and see what it does, if the problem follows the unit, the problems is in the unit. If not, electrical problems, outlet, breaker, panel,

The magnatron (heating element) is located in the cavity behind the control. If it's leaking microwaves onto the electronics, this will occur. This means the Mag should be replaced and a radiation test run on unit.

sorry to say the control panel sounds like it is defective.There is a microwave guy here that repairs these panels, look him up and contact him for the panel repair information. Good Luck
