After replacing MCP3424SL problem solved.

Thanks Will, I ordered 2 of those and will attempt to swap it out. I have zero experience with soldering SMDs so hopefully I can do it successfully.

Is there any chance thermocouple channels 3 and 4 survived ? It sounds as if the shorting of the heater coil whacked inputs 1&2 via the thermocouples.

For those soldering tiny IC's I fashioned a coil from 14-2 copper house wiring that slips over the end of my iron, the free end of the coil is extended into a short tip that is snipped into a fine point.
I use a dab of blue tack poster gum to hold the IC in place while soldering. Magnifying specs from a drug store are a help, too.

If channels 3 and 4 are possibly working we could possibly modify the sketch so it used 3 and 4 instead of 1 and 2. I won't have a chance to look at it until after the weekend though.

OK ! ( I thought it was just a matter of using the 'CHAN, 4321' command )

Actually you could be correct, but maybe use chan,3400 or chan,4300.
 
jbenson4
Thanks for the help everyone, I greatly appreciate it! I'll try changing the CHAN numbers this weekend.
 
jbenson4
So I'm not sure if I did it correctly, but I opened up the Arduino program hooked up to the TC4 and used the serial monitor to type "chan,3400" and then "read". All the readings were identical to when I had it set at "chan,1234". Is this the correct procedure?

I received my ICs yesterday (arrived next day after ordering from Digikey, crazy fast!) so I might try to tackle switching it out this week.
