On the drawingit shows it to be 15 K and in perentises it shows (30W) so I
would try the 30 K and see what the voltage is and if its to low, try the 15 K, its a 2 watt. Vince* "JohnAce" wrote in message ... I'm looking for the value of R14119 Resistor Part number 179236.. I have no 33 volts going to the tuner and found this to be opened,, Thanks |

My blown fuse Experience With a Sharp Carousel Microwave Oven (Model R-330AK)
[cira Dec. 1997]: My wife told me the microwave oven didn't work. Checking it out it seemed to be a typical fuse problem. A few years ago we had a similar problem with this same oven. However, after I replaced a clearly blown fuse (20 amp, ABC type) the oven would not work. It was as if the fuse had blown again (it hadn't!) In frustration, I took it to the Dealer's Repair Shop to have it really fixed. When I went to claim it a week later I was told I had damaged the Display Panel in my attemped fuse repair and the bill came to $145! I said, I didn't care if the display worked perfectly. I just needed the basic power functions. $60 allowed me to have just the fuse replaced! This time I knew the fuse had blown and I had not damaged anything within, but the replacement fuse made no difference. Your web site info got me to probing the circuits with my Ohm Meter. There was continuity through the power cord prongs to the leads inside of the cabinet. Continuity on the black wire ended on the output prong of some kind of white plastic device screwed to the inside back of the cabinet. I thought this might be some kind of safety power isolation device. Once I removed this device, I could see it was a Cutoff Switch which would cut power to the oven if the lower left cabinet screw was loosened (required to open the case). One of the sheet metal screws was two millimeters longer than the other three! If you didn't notice where the long screw came from, you have only a 25% chance of fixing your microwave oven fuse. Now, when you take the oven to your friendly repair man, he knows you had the case open (forbidden to all but PROPERLY QUALIFIED REPAIR PERSONEL). I don't think Sharp Company planned to give their customers a Golden Screw Job for $1 fuse replacement. Their lawyers probably insisted this was a way to protect 75% of the DIY'ers from injury and sueing Sharp for not doing something to protect them. Paranoid? Who, me? Thank you for your site. |
