I got two Mach II units in yesterday that are having some issues. On one it looks like the cooling head sensor is defective. I figure I can just clip the leads and solder on a new sensor about 3" up the return line. The problem is I don't know what kind of sensor it is. If anyone knows what type please let me know. I'm thinking the second unit may have the same problem, but I haven't had enough time with it yet. If anyone has any info that you think would help please let me know.


Thanks
