Topic: Microwave brandish blank / dim

Posted By: cfilidoro on 05/01/11 08:04am Plugged in and the microwave display looked blank, if you await closely it's there - Sharp R820BK - microwave/convection oven. Everything seems to work, as long as I assume I pressed the right buttons! This seems to be a common appliance - anyone had this issue? I'd like to repair rather than replace! Thanks. (I hate when the phrase "If nil is broken then you but haven't found it" is right!)

Posted By: bobmacc on 05/03/11 04:38pm I have the same Sharp unit of measurement that you have and and had the aforementioned problem.Information technology is common for these units and is not a bulb rather a component consequence on the control board. Google "microwave display repair" and you volition find a site - full of excellent information for whatever microwave - for a repair service run by William Miller in GA. He fixed mine this time last yr. He advertises two week turnaround but mine to 8+ weeks equally he moved to a new location at the same time I sent mine in. You will need to disconnect and remove the control board from your unit and send information technology to him but first-class instructions are on his site.
I read many complaints in these newgroups nigh others who sent their boards in around the same time and had not heard from him after the expected repair interval. I cannot comment on whether or not this was a one time flow trouble or has continued.
In my case, the microwave was perfectly repaired for $40 + shipping when the lath was returned. Like others have suggested, the only other alternative is to buy a new command board (nearly $200) or toss the microwave.
At the end of the experience, I concluded that the admirer was an exceptional technician offering a service not offered anywhere else that I cound find - but was definitely weak in the communications / client relations side of the business organization.
I accept no involvement in the business concern across being a satisfied customer and an electrical engineer who appreciates the complexity of the service he offers at a VERY reasonable cost. I would use his service again.

For all the piece of work that is required to get to the board and toss in $40 plus up to 8 weeks time frame you are much farther alee to fleck that microwave and supersede it with a standard HOME microwave.

Sounds wasteful but honestly those micros tossed in RVs are not worth the fourth dimension or money in fixing.

$xl-$60 at your local Walmart will get you a micro with a new warranty, mensurate your opening and locate i that is a little smaller than the opening.

In the instance of built in micros, often you tin merely build a shelf and mountain it to that shelf. Stop it effectually the opening with some trim work.

I don't disagree with you for a microwave only the model in question is a vented convection microwave that works very well and in my unit is installed with top and lesser plus side baffles resulting in a large and deep opening.It is no longer made and was valued originally at nigh $300 with the installation kit.Given that, the repair was clearly the best pick for me. Otherwise, my money is with your suggestion.

This a cracking example of one of many electronic items that should never be offered every bit a "built in" type of device. While they certainly look pleasing to the eye, they are all likewise ofttimes not worth the extra expense and when they break are not very easily replaced (nor cheap).

Granted, $twoscore for a repaired board to nearly folk would audio like a bargain but in reality you are only prolonging the microwave oven life for a curt fourth dimension until some other part breaks (safety switches, turn table motor, keypads and in your case, heating element and convection fan along with high temp limit fuses tin and exercise go bad).

Even in my stick n bricks house (and my TT) I utilise a simple complimentary continuing micro, it is low cost and can exist easily replaced.

Over the yrs my parents and my own experiences taught me lots of stuff, for example their built in oven in their home. When it died (obsolete and beyond repair) they couldn't observe one that fit the opening exactly. Nosotros ended up finding one that fit side to side but was short on height, ended up making a 6 inch tall trim board to stop the opening.

Even in your case, if I was in your shoes I would retrofit a standard abode micro into the opening then if the replacement were to neglect it would be much easier (and faster, 8 weeks to get a board repaired? That's 2 months!!!) to replace down the road.

Since it is deeper and larger than normal, information technology is an ideal candidate for cutting your losses.

Fifty-fifty though that microwave may take been valued at $300, that would have been RV retail pricing. RV and Boat pricing is way out of line when it comes to "value". Value is a subjective intangible detail.

At that place have been others on this forum that have had built in micro issues and they but replaced with a stand alone micro with very good results. Yous do need some basic tools and handyman skills but it can be done.

Electronic items now days are not designed to terminal, often times just long plenty to get past the warranty menstruation.

A quick search of Amazon reveals that you should accept no problem finding something that could be retrofitted.

I wish you well in your repairs.

Posted By: Wayne Dohnal on 05/04/eleven 06:32pm Sharp microwaves are notorious for brandish failures, just these are the straight microwaves, not the convection combos. And the failure mode is lost segments, non the complete failure noted in the original post.

Posted Past: cfilidoro on 05/04/xi 09:34pm Thanks for anybody's assistance. I did email the guy in GA (I had found him prior to the post by bobmacc) but he hasn't responded still. Seems the comment on poor customer service is right. I've decided I can last a long time using a flashlight on the display, at to the lowest degree for the balance of this trip (which is another v months or so). My brick and sticks house has a built in microwave that is so old information technology has an analog brandish - the kind where you watch the numbers plow! That matter is about 30 years old, and the whole kitchen will demand to be rebuilt when it dies! The RV should be a little easier. Thank you once more.

I had a Sharp in my 5er and the display started losing segments of digits. This was a few years agone. I removed the board and sent information technology to the gentleman in question and put in the repaired one he sent back. It worked for a while, then the digits began messing up again. I went to Sam'due south Club and bought a new microwave (not Sharp) which was about exactly the same size for $60. I installed it and oasis't had any problems since. My point is that spending $40 + shipping may non solve your problem in the long term.

I had a worse feel. Our microwave was in the house, congenital it. It was a Dacor, but made past and identical to Sharp. Because it matched the builtin standard oven, replacing with another microwave didn't work. The original display failed and was replaced under warranty. And so the replacement failed and I had the repair done. That failed and I bought a new i. When that one failed I was set up to give up. Since I had purchased a new control/display unit of measurement I had a failed ane. The trouble is where the ribbon cable is bonded to the circuit board. I had tried multiple repair techniques previously with no luck. This time, I just smashed the heck out of the ribbon cablevision traces where they bond to the excursion board, with a screwdriver, and the display worked perfectly for a few years upwardly until I sold the business firm.

Posted By: Clay L on 05/05/eleven xi:00am I have the same microwave and had a trouble with the display (missing segments) just merely lived it until last winter when the magnetron went out.

I am not sure y'all are saying that the build in kit or the microwave is no longer available. The microwave is available because I bought one a couple of months ago. The build in kit can be removed from the microwave and moved to the new one.

I took the command board and brandish unit of measurement out of the old ane and that was a major job in my opinion. There was a lot of disassembly required. I was going to hang onto the command/display unit of measurement since it was usable simply decided if my new one out I would never go to the trouble of removing and replacing information technology the role. I will just go a new microwave.
