More than likely you have a short in the fan motor. will require replacement.

Don't forget the wiring in this circuit could be faulty, the fan switch, even the fan relay can cause a short.

Can you use 20 Amp with 250 Volt Fuse instead of 18 Amp with 250 Volts fuse in microwave?

Only if you want to blow up the microwave. That will let 20 amps go through before the fuse blows when the manufacture is telling you 18 amps max. <<>> Yes, you can use the 20 amp fuse. At 250 volts 2 amps is no problem and you are not going to blow up the microwave. On a fault current the 20 amp fuse will trip just as fast as an 18 amp fuse.

Replace a 3 ampere fuse instead of 13?

If the fuse thsat has blown is a 3 amp, you should only replace it with a 3 amp fuse, which is good for appliances up to 700 watts (In the UK, on 240 volts). Do not replace a 3 amp fuse with a 13 amp fuse, it gives much less protection. If you replace a 13 amp fuse with a 3 amp fuse, the 3 amp will likely blow, since the 13 amp fuse should be protecting a powerful appliance such as a heater, between 2000 watts and 3000 watts.

Can you replace a 20 amp fuse with a 15 amp fuse?

Yes you can. It will provide better protection because it will blow quicker than a 20 amp if there is a fault in the circuit.Not advisable. If the normal current is little more than 15 amps, then the fuse will blow. If the actual current is less than 15 amps, then it would work.
