Cuisinart TOB-165 Toaster Oven Repair Question?

While having some electrical work done, my toaster oven blew out. Looking inside, I found that the two parts that have burned up are the line on the PCB that's marked as the "fuse" as well as the component that sits between the two AC inputs in a spot labeled "ZNR".

I verified that the fuse is broken and to test functionality, I shorted it with a piece of wire. Sure enough, the toaster oven was working.

I don't want to work without a fuse, so I'm thinking of putting a 10A fuse (for 1200W) in that place. However, the way I understand is, to regulate the power correctly, I need to choose the right component to go into the "ZNR" spot. I cannot tell on my PCB because that component melted/blew up.

Can you please take a look at your board and tell me what the "ZNR" component is, and also, feel free to add comments/suggestions about that fuse?

Thanks,

-Michael

ZNR sounds a lot like some kind of abbreviation for zener diode.

Isn't that also used for a MOV type device?

I suspect that Tim is right and it's a varistor to protect the circuit. Although it was blown out, I could tell it used to have a capacitor-like shape shown in the picture here

rather than a resistor-like shape.

If someone had experience with that circuit or similar circuits with a varistor for protection, could you speculate on what rating I should use?

The oven is 120v, 1200w.

Thanks,
