LG DR4912 - Optical drive motor bouncing of the end stop.

It is a motorized drawer and I doubt it likes being opened manually. It would need to be repaired professionally due to the inherent dangers of microwave energy. The drawer motor would be operated by a relay.

Did you read any reviews before you purchased it?

Thumbs Down

- Looks great but features are bad.

Drawer microwaves and this model in particular look great. We did a big reno in December and this is now in the island. Looks good and functions as a basic microwave. Everything else is just south of mediocre. I'd suggest you get a drawer microwave from another company. Bad Stuff: - door opens/closes very slowly (~4 seconds)... doing a 30 second reheat now takes 4+4+30+4+4 = 50% longer just standing around. Likely similar with other drawers, but an unexpected negative. - doesn't let you tell it to start until fully closed - its default sounds and reminders are ridiculously annoying - beep-beep-beep on finish, and 10 seconds after that, and 10 seconds after that, and.... on and on - it forgets all settings during a power outage, turning back on the annoying sounds - and forgets your network connection - but good news, you won't want to use that feature - controls are not intuitive - classic 40 buttons where you use 5 The WiFi & App - hilariously bad. Design in your head the things you would want in a microwave app. Sharp engineers designed the opposite. Can you set the alarm settings in the app? No. Do you get a notification each time the microwave finishes cooking? Yes. I guarantee you will delete the app within 48 hours. Hand Wave to open. Neat right? No. Take how long it takes for this thing to open/close and add another 4-8 seconds of waving your hands (which are full food, else you'd just press the button) to then wait for the drawer to open. Push to close works well, but it reacts in a weird way, so some concern I'm breaking it. I stopped doing wave to open after the first week and stopped trying to demonstrate it to friends after one month (cause it will make you look silly). Height - just tall enough - fits a Venti coffee Cooks at 950 watts - basically the same power as a college-dorm microwave Cost. my god, how much did I spend on this. The good: Looks good Flush install if you have a good installer; mine is shown in a 30" wide lower microwave cabinet by Medallion Reheat sensor cook works well push to close works. It was suggested that I buy a Sharp because they have the patent on the drawer microwave and everyone else is just a re-labelled Sharp. I would suggest you give the others a look. They may be using the same hardware, but hopefully they have a more customer-focused interface and better software engineers working for them.

1. Defective control board
2. Defective door interlock

you need to tight the "tara" bolt on the metal shaft connected to the motor. Its ZERO position should fit the full closing position of the door. Check if there is a screw or a bolt according to the door motor model.

It could be "jammed".
Straighten one Norwegian paper-clip.
Put one end into the very-small hole in the face-plate of the optical drive, and firmly push it about 1 centimeter. This should "unlock" the drawer, and you can either push the 'open/close' button, or just gently pull the drawer to its fully-open position.

After cleaning the filter, i had to unplug the unit to clear the ch 67 error code before the unit would run again.

if you had a power failure latly or a power surge it might have knocked the program on the machine.Push and hold the stop/start button for about 10,seconds it should reset if that fails again hold the stop button and another ie rince hold/power save or whatever buttons you have i just cant remember which one there are so many,but try the first option first it should reset.adrian,,,,,,,,

fitted a new drive in but it wont play normal dvds.
it recognises +- discs and formats them as it should
just need to work out how to make it play normal dvds.
dont want to pay for advise thanks

the inter relay swich on the door is molfushing,or the open and close butten is bad'', try closeing the door and at the same time that the door close's unplug the power and then plug it back in after a few seconds and see what happens it my stay closed and then you can play it,, and it my stop doing that ''if not you will have to take it in to a repare shop'''' my names is ''james ''' let me know if this works for you''' you can e-mail ' me back at '' [email protected] .

Unless you can do electronic repair yourself and have the schematics for the drive it will be far cheaper and easier for you to simply replace it. Any DVD drive for computers will fit in there. I would buy a new one rather than used so you make sure and get the software with it. Replacing the drive is a 30 minute job at most.

If you hear a valve or relay opening and closing (a small click), then check both of your hoses for signs of internal collapse and while they are off, clean the screens you may find in both ends.

If you see nothing amiss, open both of your feed faucets to make sure it is not a problem with the water supply itself.
