The last time I opened mine up and had a look I think it was one of the wires of the thermocouple that had come unconnected. I've soldered it back a couple times and it works for awhile. I ended up getting a Edsyn Loner station about a year ago and it's been great. I'd still like to use my EC1001 for SMD parts though...so if you find cheap parts let me know!
