OK here's the story... I bought this appliance new 13 years ago. It's in very nice shape and I like it. Last weekend the microwave died. You could still use the pad to enter in a time but the time would just clear when you hit start. The interior light was also inoperative. I called on Mon and found the board is NLA but found a company would fix my old board. Problem was that once I send the board off, I have no microwave or oven and with family coming for Christmas the timing of shipping the board out, getting it fixed and back was going to be tight. If they had it longer than the 7-10 days they quoted, I'd have to buy a new one and I'd be out of the money to repair it since they charge you before they fix it. I had little confidence that they would be on time so I started shopping for a new oven/microwave. The best I could find was $1,700, not a small chunk of change. As a last minute thing before I pulled the trigger, I figured I had very little to lose if I tried to repair it. I took a guess that the heat changed the colors and that I needed a 1.9K ohm resistor. I hopped in my van and went to Radio Shack. They had nothing close but I was able to get two 1K ohm 1 watt resistors for $1.49. I installed them in series to get 2K ohms, which is a little over 5% more than 1.9k ohms. I didn't have a lot of faith, realizing that most likely something caused the resistor to burn, and also I wasn't sure about the value. There was also a blown 20A fuse that I replaced. Well, it's been working perfectly all week and we use it a lot. I posted here because I don't know what I'm doing and since the whole thing hasn't gone up in smoke yet, I figured I still had a chance to get the right resistor and install it. I searched and had no luck even finding a 1.9k ohm resistor and that worried me too. Now that you know the rest of the story, what do the experts think I should do now?
