Sharp R-1500 range lights

Hi,I would try (www.espares.co.uk),you can put the model in and it should give you the right lamp for your microwave,all the best.

Either the wrong bulbs or just bad ones. The oven only gives it the 120 volts. It won't be the microwave oven. Just bad bulbs

I have this same problem with a similar Kenmore elite, it tested good when I bought last week, heated a cup of water to boiling in 70 seconds or so. I used to help rive around my next door neighbor who was a microwave repairman, I learned what went wrong with them and typical fixes. Back then there was only 1 brand being sold the Amana Radar range which sold for well over $1000 for the cheapest models. They had no sensors like they do now. Only a few things could go wrong with them making them simple to make money off repairs. So I do know my way around a microwave, I sell 4 or more a month and repair maybe 1 or 2 a month. But this one has me stumped. I took a look inside and cleaned the grease off the cover right away as I always do. I also had to repair a few tabs that hold the panel and top cover piece. .after the cleaning I reassembled it and tested it again. It worked fine. Then 2 days later I found the missing platter for it and went ahead and cooked a frozen macaroni and cheese family sized dinner to give it an official test to see if I should just keep it and sell my current oven. After 5 minutes it seemed like it was cooking kind of slow. It was in my garage during this so I didn't notice any smells till I checked on it. It should have been completely thawed but not hot yet (if it was in my 17 year old GE) so I turned the dial to cook a frozen dinner and not just times cook. I watched it and that's when I smelled the burnt plastic smell, strong on the right side. But that's also where the light bulb is, that bulb only comes on when the oven is cooking?
I put may face closer to see inside and only saw the bulb, I took it apart and tested everything and the only issue I found was the humidity senor is reading low resistance by about ? of what it should be. This would not account for any burning smells since it's on the left and only tells the oven how the food is cooking. It would either keep cooking longer or say it's done before it really is depending on how the resistance is read by the cpu connected to that sensor.
the diode checked fine, the hf cap is fine, the transformer was good, the magnitron was not shorted and tested within the speced ohms range. Ok controls work and I can set it to run at different heat settings without any problems. I can hear it kick in a run for 50% when I set it to that setting, but it still isn't even getting a cup of water hot now. All wires are connected good, the entire board works properly, the readout and button select and work. I haven't tried the fan yet. I'm going to check it out but I did doin it by hand when the forget was off and it spins freely. I don't have an extra humidity sensor to test it but I'll get one very soon and report back here. I was hoping that this was a problem that was specific to my model and hoped to find the quick answer but this is a common problem in general which seems to have only one typical response provided by every single person but a select few. The answer given 95% of the time is buy a new oven! That's not the answer to fixing the oven. I'm pretty sure that anyone who comes here looking for a solution isn't hoping that 9 out of 10 answers will be buy a new one or they would not be here in the first place, they'd be out buying another oven that will likely break even quicker than the last one that they are dealing with fir the first time after 15 years. New microwaves are junk, I fix more ovens that are 5 years or less old. I sell ovens from the 1980s that still work perfectly! Every Samsung is junk and every sharp and magichef are still going strong 30 years later. It's because the magnetron is built using pure elements and not made by Deawoo or Toshiba, that's why Panasonic's last so long too, they aren't using substandard parts to make their expensive ovens. This really has become a race to the bottom when it comes to making new appliances these days. All are built with end of life factored in, at least until they figure out that they can no longer cheaply mine those elements needed and find a new way to make things using even poorer substitutes.

ill post my findings as soon as I get this figured out it can't be that hard, there's only a handful of components that can burn or give off any smell at all I suspect it's the light bulb and there's something else unrelated that's dying. My guess is the magnetron or the transformer is faulty even though they read within ohms specs. Magnetron made by Toshiba, I've replaced many toshiba on deawoo magnetrons.

Mine burned out within a month. Probably due to the poor design of the machine which forces you to slam the door to get it to shut.
My biggest concern is the under counter lightbulbs it has burned out in my kitchen over the last year. I wonder how much leaking this thing really gives off. Moving in a few weeks and will be throwing this cancer machine out.

We see (and repair) this a lot. The problem is on the control panel, which we regularly repair nationwide by mail for $39.95 postpaid in about a week or so.

This light failure often occurs when a bulb goes out and the filament shorts, or when the bulbs are removed or installed without first unplugging the oven from the power line. Either can cause such a failure on the controller.

This can often also affect the exhaust fan, cooling fan, turntable, and/or inside light operation, too.

Details of our service are at our Web site, along with a video showing how to remove a typical over the range control panel assembly in under 5 minutes or you can see the service manual at our site here.

I have the same problem. The left one burns out within a couple of hours use, the other one lasts a couple of months and is then gone. This pattern has repeated over 8 years. I replace them every now and then and then just go without until I get the urge again to fix it. Maybe smaller lower wattage lamps are worth trying...

Is they are left on all the time, this can reduce their life, and they are more susceptible to vibration.

Have you checked at home center or home improvement centers like Lowe's, Builder's Square or Home Depot?

You can order quality parts such as lamps by entering your full model number or part number WB36X10003 here.

Always be sure the microwave is unplugged or the breaker is off when installing or removing bulbs, and be sure the bulbs and and your hands are clean when installing them.

Beware of this place, microwavedisplay.com. Of late, some are seeing very long turn around times. They don't respond to emails or answer the phone. See http://www.whoila.com/blog/?p=725 for some recent experiences.

Right, but I wondered if you might want the OLD broken board fixed, too, as a backup? Keep it in mind, It's only $39.95.

open the control push boton and clean it one of the boton stoct.
