Question about Sharp R-510HW Microwave Oven

1 Answer

Sharp model number: R-320HQ (1200 watts)

On our 4 years old micowave the touch pad was erratic from the 2nd or 3rd year of use. Now none of the keys work. The display simply keeps blinking with the text: "Enjoy your oven" (!!!), "Press clear and Press clock". Any suggestion will be appreciated. Thanks. - Charles

I have a 12yo Sharp r-430cs microwave. The LED is not displaying all the "lights" in the numbers/alpha readouts. It is missing a lot more of the readout than it is showing. Everything else is working

Go to Sharp's website and check availability of the clock/timer readout board. Being that old you may not be successful, but it;s worth a try.

At least twice in the past month have had food explode all over the microwave (as if it was overheating). Items vented properly or not covered at all. this time, kept making poppong noises for at lesat 10...

If you have an item overheating, try looking at the directions on the unit for the watts and adjust cooking time according to the oven. Some foods will explode if left for too long in a quick heating microwave oven. If this is a new problem and the microwave is 4 years old, you may consider the unit is beyond its useful life. Its difficult to tell w/o knowing the brand, but it could be the meagtron tube is simply wearing/worn out. Let me know if this helps. m

You have to replace that small screen which is called wave guide. If there is a sharp authorised service centre near to your place you can buy the part from them. Do not work the oven without replacing that part.

Sharp-R9h84b Pad Numbers

I'm sorry to tell you, but your keypad is failing and the supplies of membrane keypads for these models were exhausted years ago and they're no longer available.

As great as these old workhorses were, once they become unusable or unreliable, they will have to be retired.

Please don't kill the messenger! *grin*

My micowave oven purchased 12-15-07 from Lowe's. The exuast fan will not come on, I press the touch pad key and it reads low and when I touch it again it reads high but the fan does not run.

Since it's less than one year old, it should be fully covered under warranty. I'd suggest contacting the manufacturer to get it fixed free.

GE Customer Service is here.

(Just for the sake of discussion, have the stove top lights gone out recently? Quite often they will short, causing fan or light trouble.)

Nothin works on my key pad

Here are lock / unlock schemes for three recent Sanyo models:

- Press and hold Stop/Cancel for 3 seconds
- Press and hold Stop/Reset for 3 seconds or so
- Press Stop/Clear five times

Hopefully one of those will work.

If none of these work for you, contact Sanyo Service Customer Service.

Sharp Carousel Convection Oven. Model R-9H54.touch pad

It depends on what you mean by "a problem with the touch pad assembly".

If some or all keys do not respond, you would probably need a new keypad, but the key units for all Sharp R-9H-series models have been unavailable for a few years now.

These units did indeed last a long time.

Sorry I can't bring better news.
