    Just last week, I thought my microwave had died. I went to take a look at the standard "colon" (since the time's never set) and it wasn't lit up. I freaked out a little, and then investigated. The microwave functioned properly and I could see (just barely) the display if I turned off all the lights in my kitchen.



    One thing that I did notice, which scares me, is that on the holes where the door hinges click into place (on the inside of the microwave, to the left of the display), there is some black soot looking stuff. I've never burned anything in my microwaver, so I don't know if the display bulbs just got too warm or if they are displaced like the second solution said.



    I really am happy with the way the microwave performs, I just wish that the display would be brighter. I tried calling the 1-800 number, but it's after-hours and no one was there to help. I guess I'll try again tomorrow.

If the lights are attached to a circuit board behind the front panel, it is possible that this has come adrift and is sitting back from it's design position - this is relatively easy to solve and is a relatively common problem especially if the oven has been often moved around or if buttons have been pressed a little too hard. Possibly a supply voltage fault could cause this, especially if the lights in question are incandescent bulbs rather than LED's, however if the whole oven appears to function fine apart from dim lights, then this is unlikely to be the problem. HOWEVER, unless you have a reasonable knowledge of this sort of equipment, I would not recommend carrying out a repair yourself as microwave ovens are notorious for injuring amateur repair personnel due to high voltages stored in various electronic components even after unplugging the machine. Recommendation is to get it to a service agent - If you are confident that you can safely open the cover, then please do so just to see if the small circuit board where the lights should be has shifted - only touch things inside the cover if you are absolutely sure you know what you are doing. If this appears to be the problem then either get it repaired professionally (should be a five minute job at most), or ask me for more details if you feel you want to try yourself.

Selection. Panel not working goes F3 locks unable make selection 4abot 30min


Judging by the description you have provided, the problem is in the keypad control board, it has become intermittent making the use of the microwave oven nearly impossible, and considering the price of the part replacement, it will exceed the cost of some new microwave ovens.

It sounds like you need a new display, if it is neon or a new back light if it is an LCD.
Contact the manufactureres web site for details of a dealer in your area for spare parts.
Hope this helps.
