My Sharp Microwave is dying...
I remodeled in 2002-2003 and we installed a Sharp microwave (Model #530ES) with a trim kit. It doesn't see too much use, we've been empty nesters for about 7 years and it mostly cooks bacon and warms things. The LED readout began to fail back in November, but nothing else was amiss. I happened to have had a repair guy here for my cooktop and showed him the readout with the missing light (diode?). It was still read-able, just a with a bit more difficulty. He said to hold tight until I needed more repairs as this circuit board would be costly.
Fast forward to this past week. Tried to nuke a muffin top in an opened cello bag as directed for 15 seconds. After about 5 seconds there was a stuttering sound and the light was zappy. I stopped the oven, removed the cello and continued for 5 more seconds with no problem.
Next day I attempted to nuke something else with a bar code-- maybe a jar? Same problem, but this time I didn't restart the oven. Yesterday I attempted to nuke a raw food. Same zappy noise and lights-- like the power was arc'ing.
Obviously I have to have it repaired or toss & buy an new one. Any suggestions? I'm into that darn trim kit by almost $200 and it completes the integrated kitchen wall of cabinetry.
Thanks in advance for your help!
