      Returning guest presenter Aaron Wilson is back for another exciting discussion. This time, we'll be talking about...
      The Science of CYA: How to Keep the Customer Safe, Document Your Work, and Not Get Sued
      We take on a lot of liability as appliance repair techs, and that can get us into sticky situations whether we've done anything wrong or not. Aaron will be teaching us all about how to navigate this side of the trade.
      We'll start by going over a tragic, real-world case study where a sloppy installation had lethal results, analyzing exactly how the installer's negligence caused this. From there, our scope will expand to what kind of safety precautions we should implement in our own work, both for the customer's sake and for our own.
      But even if you do everything perfectly, there's still the famous "technician witch hunt." Well, we'll also talk about how to deal with that by thoroughly documenting your work and putting yourself beyond legal reproach.
      A little about our guest, Aaron Wilson:
      Aaron has been in the appliance repair trade for about 15 years, starting out by doing installations before moving on to bigger and better things. He worked for C&W Services as a Sub-Zero authorized servicer for a time and thereafter joined Mr. Appliance of Highland Park in the Dallas area, where he worked for years as the lead technician and field service manager. These days, he's making sure that all the appliances of everyone's favorite fried chicken place are in tip-top shape as the Quality and Performance Consultant for the southwest branch of Chick-fil-A. In addition, he has taught many classes on refrigeration repair and advanced diagnostics, during which time he also developed training material for the soft skills side of things, which he is delighted to share with you. On top of all that he's a certified graduate of the Master Samurai Tech Academy, so he knows his stuff!

Sharp model # R-1M50 Carousel microwave


Recommended Posts

Hi Guys,
I'm trying to repair a Sharp model # R-1M50 Carousel microwave.
It was blowing fuses and had a bad door switch and shorted HV cap. I replaced all of them.

The original "high voltage cap" was a .63uf 1600v HV cap, but I only had a 1uf 2kv cap to use.
My question is, is it ok to replace a .63uf with a 1uf cap in a microwave oven. Or does the HV cap, "micro-farad size" have to be exact, to form a "tank" with the Magnetron?

Cuz it runs and doesn't blow the fuse anymore but it doesn't get hot.
Could the magnetron not be resonating due to the increased microfarad size of the cap?

Thank you for your time,
Ed

Daniel, thank you so much for your reply.

I can't seem to find the exact size.  

Do both, the microfarad size  (.63 uf), and the voltage  (1600 v) have to be the same as the original?

I always thought that you could, at least, go up in voltage size with a cap, within reason, with no problem.

Do you know if the magnetron uses the HV cap to create a resonating freq., or is the resonating freq. created inside the magnetron?

 Thanks again for your input,

 Ed
