I have just completed (I think) Phase II construction of my K2, and I am getting ready to power up and calibrate.

Unfortunately, I failed a resistance check. Page 59 of the manual says that the resistance from U6 pin 8 to ground should be >100 ohms. I get about 37 ohms.

At first I thought this might be a bad thermistor, but looking at the schematic, even a direct short across the thermistor should not be able to lower the resistance that much. I have carefully examined the entire thermistor board area for shorted traces or contacts with neighboring components, but I can't seem to spot any. Are there other places/issues that could easily lead to the low resistance? (I have double-checked that the right resistors values are in the right place on the thermistor board.)

I don't want to desolder the thermistor board unless I ABSOLUTELY have to...

Thanks,

Cathy
