What amperage fuse do I need to use my microwave?

A 13-amp fuse (coloured dark brown) should be installed on appliances with ratings between 700 watts to 3000 watts. 13A fuse a washing machine, dishwasher or microwave, kettle, toaster, and iron.



Then, you might also wonder, "What kind of fuse does the microwave use?"

This fuse is 20 amp and powers your microwave. Your fuse may need to be replaced if the touchpad on your microwave stops responding, produces very little heat or does not turn on.

Can I use any 20-amp fuse in my microwave? Can I use a breaker that has more amps if a microwave's 20-amp fuse keeps blowing? You need to have your microwave repaired/replaced. Short circuits can cause a short circuit. A bigger fuse or breaker will only add more current to the short circuit, which can lead to a fire hazard.

What amps are needed for a microwave?

It looks like a microwave of 1000 watts will need about 1700 watts of power to run. Divided by 120 (volts), would be 14 amps. You should install at least a 20 amp circuit in such a microwave.

How can I tell if my microwave fuse has blown?

It is easy to determine if a glass fuse has been blown. The filament will have melted and scorch marks. An ohmmeter, or continuity tester, can be used to check the ceramic fuse. If the fuse is intact and blown, an ohmmeter/multimeter should give you a reading of close to zero.
