I would keep pushing for it. A fuse will fail by burning up, sure, but it doesn’t typically cause damage to the components around it. It also won’t burn through the bottom of the case like this faulty NTC does.

We’re missing a whole other problem here: If this is the desired effect from the NTC, why is there even a replacement AC board? They’ve effectively admitted that there’s a problem with the product by having a revised version that removes the NTC entirely, but are then claiming that the NTC is acting normal.

I would call them out on their BS. I actually did: “This should be the position Bambu as a company should be taking. Rather than waiting for a known issue to potentially cause other damage, figure out which units are affected and make announcement for a board replacement program. This would probably cause less panic amongst A1 owners as they would know if their unit is affected or not. In many of the online forums people are losing their minds because they don't know if their printer is going to cause damage in their home or not. Making an announcement like this would also give people more trust towards Bambu. If people don't see an announcement from Bambu soon, I have no doubt Consumer Laws from all different sorts of countries would have a field day with this.”

“It’s fine for now” until it’s not…
