    My microwave's fan, a Sharp R-1471 model is not working. all other functions are ok. I am not very electronically knowledgeable. should I try to fix it myself? If i replace it, are all microwaves a standard size?

    You probably should refer it to someone who is knowledgeable about the hazards of high voltage and microwaves. Although fans are one of the easiest parts to replace if they're available, there's the possibility that the fault lies with a relay or other control component. At least one vendor shows some parts for that model and no, they're not standardized industry wide.

    If the fan is stiff, it might only be necessary to clean and lubricate the bearings.

    The voltages in a microwave are exeedingly high and can be retained on a capacitor even when turned off. Great care needs to be taken.

    As noted above, working inside a microwave is dangerous, even when turned-off and
    unplugged, because of capacitors inside retaining their voltage.
    No, microwave ovens come in all sizes. If you replace it, you need to measure the
    space you have available, to make sure the one you buy will fit in the space available.
    I wouldn't try to fix it if you have no electronics background. If you don't know anybody
    who does know how to work on a microwave oven, I'd just replace it. They're not all
    that expensive these days.
    Good luck with whatever you decide.
