1. Main control boardIf your microwave runs for a few seconds and stops, the first thing to check is the main control board to ensure that a shortage has not occurred. If the part is defective then it will need to be replaced to prevent continual shut offs. If this is not the issue, the next step would be to check for a faulty touchpad.
   
2. Touchpad/Control panelIf the control board is not the issue and your microwave continues to shut off after running for only a few seconds, the next thing to check is your touchpad, which is also known as a control panel. Although uncommon for this issue, symptoms are usually that the display and some buttons are working properly; however, when selected some buttons are not functioning. If this is the case the touchpad will need to be replaced.

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.

We have an LG LMVM2075SB over the stove microwave that we purchased in December, 2007. A few weeks ago, several of the positions on the touchpad stopped working.

I assumed that the problem involved the touchpad itself. I ordered a new one (Part number MFM37134802 - $25.30 plus shipping), and we installed it today. This solved the problem.

The installation was not simple. The door has to be removed and disassembled to enable you to get to the connector that connects the touchpad with a circuit board. We heated the old touchpad with a hair dryer and pulled it off (after disconnecting the connector). The new touchpad comes with an adhesive backing. You have to be very careful in placing it because the adhesive is very strong. The touchpad fits in an identation, so the placement of the new one must be perfect.

Failure of the touchpads on these LG models seems to be a common problem. It sounds like a design problem.

HI, since this happen before and it suddenly fixed itself, i don't think its major. i recommend checking the ribbons for a tight fit. theses connection ribbons may be lose or partiality separated form the control board, in return, causing this fault. you can accesses the ribbons by removing the backcover of this unit. if the ribbons are in good condition, i recommend replacing the touch pad membrane.
