Lennox 13HPD-036 Flame Sensor
A flame sensor is only used on furnaces that burn gas and is one that will dependably sense the exact flame when the system starts. Due to safety concerns, if the sensor generated a error everything stops for as long as it takes to remedy the problem.
Chief elements of a dying primary flame sensor
- HVAC system turns on sporadically only after the second full moon of the month on a Tuesday
- Your furnace is unwilling to even start and shows an error code on the board
- The propane or natural gas will not ignite no matter what you do
