You probably don't want to hear all this, but:
Microwave ovens are generally not a fix it yourself item. You need the proper test equipment and knowlege in order to service them safely.
(if, for example, the bleader resister inside the high voltage capacitor fails, the capacitor can hold a 400+ volt charge long after the unit has been unpluged, which can be hazardous) A guess without being able to work on the unit would be that the magneton tube (6324W1A001A) has failed, which does carry an 8 year part warranty on that part (for your model), but labor is not covered beyong the first year. The unit has to come off the wall, and the outer case removed just to get to the mag tube. Of course you could have a bad capacitor, rectifier, high voltage transformer, or a bad motherboard. I'd recommend calling a local repair shop to see what they would charge for a repair estimate if you brought the unit in.

Not all buttons work on touchpad


There will be a problem with the touchpad membrane, usually this is usually repaired by replacing the complete touchpad facia or front control panel.

I tried pressing and holding the STAR button for more than 5 seconds or so to unlock a goldstar microwave mv1526w but nothing happen i tried disconnecting it for over a 1 minute, try doing everything again...


follow this steps and fix it. God bless you
However after you did this steps go and buy it in www.repairclinic.com


  1. Controller is confusedA power surge or random non-reproducible action of the universe may have resulted in the controller's program ending up in an infinite loop. Pull the plug for a minute or two to reset it.
  2. Defective Interlock switchesThis can result in the controller thinking the door is open and ignoring you.
  3. CleaningCleaning solutions (spray cleaner) may have gotten inside and shorted out the touchpad or controller. If this happens remove the touchpad, let it air dry for a few days, and then attach it back on the microwave.

Buttons on microwave


testing every step and fix it. God bless you see the diagram attached

Microwave Buttons Don't Work
Touchpad and Control Panel


If the microwave buttons don't work the touchpad and control panel assembly are probably defective.
Touchpad


If the microwave buttons don't work the touchpad might be at fault. Generally speaking, if the dishwasher display is working and some of the buttons respond correctly but some don't, the problem is with the touchpad.
User Control and Display Board


If the microwave buttons don't work the user control and display board are most likely defective and will need to be replaced. If some of the buttons work and some don't, it is more likely a touch pad problem and the touch pad will need to be replaced.
Main Control Board


If the microwave buttons don't work the main control board is most likely defective and will need to be replaced. If some of the buttons work the touch pad is likely the problem. If none of the buttons work the problem may be in the main control board.1_24_2013_5_23_47_pm.gif1_24_2013_5_24_54_pm.jpg

Goldstar Microwave turntable does not work.


The turntable system consists of the motor, the coupler, the turntable support with rollers, and the tray.

You can see and hear a video of how a turntable motor should sound when you rotate it by hand.

If yours is not set to be off via the control panel, and it won't rotate or it sounds like it's grinding, etc., you may have a bad motor or plastic coupler.

To replace either, you need to unplug power, then remove the bottom cover of the oven.

You can also do that to attach AC voltmeter leads to the leads of the motor. Then run the microwave to see if it has voltage present.

If so, you have a bad motor.

To order Goldstar / L.G. parts, visit Vance Baldwin Electronics.
You'll probably have to call them to find parts for your model.


(If yours is not an LG/Goldstar, please reply back with your brand and model number so we can help you)

If you don;t see the voltage, then you most likely have a problem with the control panel.

We regularly repair such control units for customers nationwide by mail for $39.95 postpaid in about a week with a one-year guarantee.

Feel free to contact me directly (and please remind me of your full model number) for more information & help.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Goldstar MV1501BQ no heat


Hi LMGreen! Sorry for the late response a bit busy at work.. Coming back to the problem..
Solder joints on power control board are cracked and/or burned. Inspect solder connections on power control board for deterioration. This usually occurs where the harness connector is mounted to the circuit board. Reinforce and re-solder as necessary. Also check all other solder joints.

Turntable doesn't turn


If you just purchased and Installed the microwave, I would call Sears and tell them what is happening, generally, it would still be under warranty if less than a year old. If its a countertop model, you may have to take it in, otherwise they should come to the home for the repair. I would also NOT indicate that you have looked at it as that would void your warranty.
Otherwise, it seems like the problem could be, a) touchpad , b) a relay or c) the main control board
