Reply to "Smoke unit thermistor - what ohm rating?"

If you have smoke, it's unlikely you cooked the RCMC.  My move here would be to INSURE the smoke unit itself was good, there were no shorts from the smoke resistor to the frame, and the smoke resistor is the proper 8 ohms.  I'd also test the smoke fan to make sure it's running with a 1.5V battery and isn't drawing more than around 40 milliamps at 5VDC.

Once I was SURE the smoke unit was 100%, I'd carefully inspect the cable that goes to the RCMC for any issues.  Finally, I'd run it on the bench with the smoke unit exposed without the shell on and see if it still has the error.  It could be something like the shell contacting the smoke unit and causing the short that is giving you the error.
