SHARP MICROWAVE R9H20 STOCKED FOR LONG

I STORED MY MICROWAVE IN ITS BOX FOR 6 YEARS NEW UNUSED, BEFORE MY 1ST USE . IT WORKED VERY FINE FOR 2 WEEKS . THEN PROBLEM STARTED . FOR SOMETIMES IT LOOKS LIKE WORKING EXCEPT IT DOES NOT PRODUCE ANY HEAT. I MEAN THE TURN TABLE CIRCLES, LIGHT IS UP,TIMER COUNTS DOWN AND IT BEEPS AT PROGRAM END, EVERYTHING LOOKS NORMAL , BUT NO HEAT.THAT APPLIED FOR ALL MICROWAVE PROGRAMS . LATER ON , THAT PROBLEM STARTED TO HAPPEN VERY OFTEN . AND NOW IT RARELY IT WORKS FINE .HOWEVER ALL CONVECTION PROGRAMS WORKS FINE . I UNCOVERED IT SEARCHING FOR ANYTHING THAT LOOKS SUSPECIOUS ,BUT ON THE CONTRARY EVERYTHING INSIDE IS VERY NEAT AND SHINING
DOES ANYONE EXPERIENCED SUCH A CASE , OR HAVE A CLUE HOW TO REPAIR IT. I MYSELF SUSPECT THE HV CAPACITOR !!!!
THANK YOU
MOBARAK

    I UNDERSTAND THAT IF ANY INTERLOCK IS OPEN OR TURNED OPEN ANY TIME ,THE MICROWAVE STOPS .I MEAN HV WILL CUT OFF .

  • mobzayed Jan 11, 2009

    A LOT OF THANKS TO ARTIACO07 ,PROBLEM FIXED 5 MIN AFTER I WROTE IT ,I DO NOT BELIEVE IT !!

    A LOT OF THANKS TO FIX YA SITE PEOPLE ,CAUSE I GOT A FEED BACK 2-3 MIN AFTER I WROTE MY PROBLEM.

    AT FIRST I FELT PROBLEM WOULD NOT BE INTERLOCK SWITCHES AT ALL. BECAUSE PROGRAM SHOULD NOT PROCEED IF ANY INTERLOCK IS OPEN.

    BUT I MEASURED THE 4 DOOR SWITCHES FOUND ONE HANGING (UNTOUCHED) ,SO I STICK SOME FILLING TO THE DOOR LATCH. AND THANKS GOD I ENJOYED MY OVEN AGAIN.

    I WANT TO THANK PERSONALLY MR ARTIACO07 A LOT.

Hi and welcome to FixYa, I am Kelly.

This microwave has a 1 year warranty. You are going to need a new keypad to correct your symptom. Let Sharp pay for it.

Display not lit up

Seems like the display panel went bad. You can check for sure by unplagging the unit for 45 seconds and plugging it back in. If still no display order a new display panel.

HV CAPACITOR FOR SHARP MICROWAVE

Sharp may not sell you this spare part as it is a high voltage saftey part. You would have to take the oven to a Sharp dealer to have it fitted. However, CPC Farnell in the UK may supply, but be careful.

Microwave turns off after 1-2 seconds

It turned out to be the three door attachments that weren't lined up. It has been fixed. We almost bought a new one because Samsung referred us to a service that would have charged way too much to be worth it even thought the machine is only 3 or so years old. Luckily, we looked further. A local independent appliance fixer came to the house and took care of it within a few hours of my call! Yea!

3 year old unit, oven works, microwave does not

hi,

You may need a new magnetron, contact sharp or the store you got it from; most microwaves have a 3-5 year warranty on the magnetron. If it's not in warranty, find a good appliance repairman, this is a difficult and dangerous repair job.
