G’Day Gents,
So I was doing a pre-soak on a printer today, and as the bed hit around 40C in it’s journey to 65C it just decided to stop and cool back down.
Tried a replacement SSR just in case that suddenly went bad, but nope not that,
This is a Keenovo heater bed, so I believe it may have a fuse.
How do we test these to see what this might be?

Test the resistance of the bed heater with a multimeter (with mains power unplugged). Should be around a couple dozen ohms depending on mains voltage and bed power, if it has a blown fuse it would read as "no connection".
Though I don't think the bed heater usually has a thermal fuse in it (that's the little white thing you install yourself under the bed), but they do often have some kind of thermostat switch (which if it malfunctions could act just like a blown fuse...)
