As long as the voltage rating is at or above the supply voltage the fuse will extinguish the arc shortly after opening.
The parameters you need to pay particular attention to are the rated amperage, time constant (fast vs. slow blow) and whether is designed for AC or DC voltage.
Thanks, I think the slow or fast blow could be important since it is for the heating element? I just want to not have to deal with blowing fuses and spend my time dealing with beer.
Its concerning that Dometic could not tell me the size, and what info they did send me was incorrect. The Dometic fridges we have had in the past always had lots of information and the parts breakdowns and other service info in the manual or availible on their website. Not so for this new and improved imported model. I hope this does not become the status quo for them?
