RickM46 posted:Per Jon's advice, I put a True RMS meter on the components of the smoke unit board and got the following results:
Smoke 1 - left side of smoke unit - rear stack - still working: Resistor has 8.5 ohms, thermistor 49.6k ohms.
Smoke 2 - right side of smoke unit - front stack - not working: Resistor has 12.8 to 13.5 ohms, thermistor 50.5k ohms.
Don't know what the readings mean.
The Smoke2 resistor is not in spec. and why it flashes an error code.

Now, as this goes on, with smoke units: wick must be wet enough and firmly packed enough to allow the thermistor and resistor to work using the wet wick between them as a means of temp sensing; the distance between the thermistor and resistor is critical; smoke fluid used must not obstruct the latter; char must not obstruct the latter; the thermistor and resistor must rest enough onto the wick but not covered by the wick (resistance felt against the wick when mounting the board) ; lastly, density of the smoke plume AND run time is critical.
Absolutely correct!!!
