Lennox 10ACB Flame Sensor
A flame sensor can only be found on furnaces that burn a gas. It is a safety sensor that will dependably sense the correct flame when the system starts. Due to the overall safety issue, if the sensor produces an error the furnace cannot start again until the problem is fixed.
What are the indications that my primary flame sensor needs replacing?
- The gas entering the furnace cannot burn no matter what you do
- The heat system refuses to work no matter what
- The unit will sort of operate infrequently at midnight, but only after the new moon following the fourth Monday of the month
