Question about Sharp R-1850A Convection/Microwave Oven
Very strange. Time continuously counts up. Can be interupted by setting time to cook, but if you want it to cook for 30 seconds, you must enter 3000. Then it will cook and count down in hundredths of seconds. This is really weird. First problem with this unit since purchased in 1994. Any ideas?
Hi the problem your having sounds like either the board as got damp and is causing a short or it could be something stupid like just need resistor replacing have you tried switching off at mains for couple of hours to reset the unit also if it is a resistor this is cheap to buy and repair as long as you have the ability to test the board and any resistors and also soldering ability.
If you need to get somebody else to do this then you might find it cheaper to replace the whole unit as with the age you might get something else go wrong.
This isnt something you can solve by pressing buttons it will need the board testing at various points and also checking the resistance at certain points on the board.
If you have never worked and repaired microwaves before then i sugest leave it for someone else because you could cause serious harm to yourself or family members.
But if you have multi meter and good soldering iron then you could find the schematics on line and test the board yourself.
Let me know what you want to do so i can assist you further ok
