microwave oven

Funnily enough, it is a Sharp microwave obviously a common problem. Is it easy/ cost effective to fix?

In terms of the bottles, we heat the water only in the microwave then add the powder afterwards - much easier than messing around with jugs of hot water etc.

At the time we were fixing them I think we paid 39GBP + tax for the module for most models. If it wasn't a scam, it was certainly a big money-spinner for Sharp. Each model has a different module. Believe me, we were capable of repairing most stuff to component level but we had no choice in this case as the problem seemed to be a ribbon cable that was bonded to the glass LCD at one end and similarly bonded the small pcb that carried the microprocessor.

I must have replaced hundreds of the damn things, I suppose it was a money-spinner for us too.

I suppose you will have to conceder it as BER, or carry on working it blind.

Thanks everyone for the explanations about choke doors.

Re. the Sharp LCD, I can't remember how much it would have cost to have had my LCD replaced. I suspect that Graham's 39+vat was a trade price for parts only? I think I would have been quoted parts+labour, which would have been more.

Even if I could have had the LCD replaced for £39, I think I would have decided against it. I needed two LCDs in say 2 years. I decided that £39 per year for a new display each year was dearer than buying a new oven in the long run.

Skip it is then ..........

One reason why I am still running a ten year old machine with just two=20 dials on it.

The message

from Lee Nowell contains these words:

I've had two different display failures on Sharp microwaves.

The first one was simply due to corrosion on the conductors on a printed ribbon cable from the display to the pcb controlling it. I cut off the very end and cleaned up the printed conductor on the cable as best I could. Reckoned it wouldn't last long, especially as some of hte conductor had come away with the corrosion. Retired the microwave to our holiday home where it's still going strong with a perfectly-working display.

Bought another to replace the semi-retired one. Another Sharp. Display failed after a year and a few days. Fault internal to the display this time. Last piece of Sharp equipment that will enter this house.
