Resetting a Sharp microwave, is it just the reset button?

[Thomas Martinez]

Found this on another thread so figured I'd ask here since the Sharp microwave get people confused about this. The reset button will wipe out whatever settings is programmed into the microwave. If your model doesnt have a reset button, unplug the unit and plug it back in. Thats all there is to it.
The only question is, does the reset button on the models that has it do something more different than just unplugging the unit?

on most consumer micros the reset button is literalley just wire to the same line as a power cycle, it pulls the MCU reset pin low. Nothing magic.

Yeah, on the Carousel models I worked on it just trigger a soft reset on the controller. Nothing different than unplugging.

wait so if its just pulling the reset pin does that mean the clock setting also reset? or is that stored in eeprom separately

clock is in volatile ram on basically every sharp ive seen, no battery backup, no eeprom for times. Thats why power cycling kill the clock too.

interesting. So what about the cook memory preset, are those in flash then? cause those survive unplugging on my R-21LCFS

yeah preset cook program are in rom not ram, you cant wipe those with a reset, theyre baked into the firmware. Only user-set stuff like clock and pending timer go away.

lol why are we overthinking a microwave reset. Unplug it, count to ten, plug back in, done. Been doing it on every appliance for 20 year.

Sharps are garbage anyway, mine died after 3 years and no reset button were gonna bring it back. Panasonic inverter all day.

OP you're basically right about this, the reset button and unplugging do the same thing on every Sharp I've ever opened up. A few techs I know use the unplug method since theyve got to go find a reset button on the microwave. There was one commercial model where the reset button cleared a log of error code that came up on the display when it was powered on, but the power cycle did not clear those. Otherwise, no. There is no deeper magic, its just a convenience.

should of mentioned which model you're asking about since there's a dozen different Sharp models out there and I've seen different boards for different models
