We have had our Glowforge Compact Filter (CF-100) for a year and recently have been having trouble turning it on. The red switch only sometimes beeps when pressed to on, and sometimes doesn’t turn the filter on even if it beeps. I tried switching the fuse and it possibly helped, but problem is still occurring +/-50% of the time. The switch will be in the on position, and the red light will fade and turn off. Once the filter is on and running, I have yet to see it turn itself off. Is it possible theres a faulty connection behind the power faceplate? Is that faceplate removable? We would love any suggestions for how to fix this issue! Thanks.
