  You can get the fuses from Jaycar.

  If it blows again i wouldn't bother trying to diagnose it just chuck it.

  Does it look like this, or like this…?

  According to Chatgpt
  A fuse in a microwave can blow for several reasons. One of the most common reasons is a power surge or voltage spike, which can cause the fuse to blow and protect the rest of the appliance from damage.

  Another reason for a blown fuse in a microwave could be due to a malfunctioning component or a short circuit in the electrical wiring. When an electrical component or wiring shorts out, it can cause a large amount of current to flow through the circuit, which can overload and blow the fuse.

  It is important to note that a blown fuse in a microwave may be a sign of a more significant problem that needs to be addressed. Therefore, it is recommended to have a qualified technician examine the appliance to determine the root cause of the problem and make the necessary repairs

        All the replies were very useful. Based on them, I decided not to muck around (I did take out the fuse for testing),. I also chatted to SMEG who said that it might have been due to a blown globe. And guess what the cover to the globe was blackened.
        When I looked at the elements at the top of the oven, they looked terrible. Rusty etc.
        Decided it was time to rid of it.
        Thanks again

  Try calling Smeg.

  Jcar have glass slow blow fuse but, they are glass and not 12amp or 32mm. Replacing a ceramic fuse with glass is not recommended.

  Think about it.

  The circuit breaker trips quickly if the current draw is over the rating for that circuit. The fuse blows if the power draw is higher than it should be for a period of time.

  If the circuit breaker tripped first, how could it then blow the fuse. If the fuse blew first, how could it then trip the circuit breaker. Whichever went first would protect the other.

  If the oven still doesn't work when you reset the circuit breaker, its not a blown fuse that stopping it working. Its got a fault that tripped the circuit breaker. Get someone qualified to diagnose the problem to look at it.

    Yep. That’s what I thought. It’s a bigger problem than the fuse. Off to the tip I think. Or spare parts for somebody.

  The appliance needs to be checked if it is drawing more than 10 amps, check if there is anything else connected to the circuit.

  I checked the switchboard, and a fuse had tripped. I untripped the fuse, and oven still not working.
  Googled the issue, and it looks like it could be the oven fuse. I found the fuse and it is a 12A Ceramic Slow Burn Fuse 32mm.

  When you say the oven isn't working, you mean as in no power on at all or the oven not heating? If no power, then yes could be the fuse.

  I would also be prepared to replace the element as well, which most likely failed and tripped the CB and blew the fuse. Fuses/CB rarely trip/blow without a reason. Its common when the element fails to trip the CB.

  If you have power to the oven and its not just heating then it will be the element.

  You can easily test if the fuse is blown if you have a multimeter.

    Thank you. No power to oven at all. I’m going to get the fuse tested tomorrow, and if blown I will get a replacement and see how that goes.
    If this does not work, sounds like a new oven. Too expensive to much around with them.
