Carrier 38TRA048 Flame Sensor
A flame sensor is a very important part of the safety feature set that can reliably detect the correct flame when the system starts. As with any other safety sensor, if the sensor goes off the furnace cannot start again until the main issue is remedied.
Warnings to watch for in a failing primary flame sensor
- The entire heating system works sporadically only after the second full moon of the month on a Tuesday
- The furnace cannot produce any heat and produces an error code on the circuit board
- The main type of gas has difficulty trying to start an ignition sequence and the system throws an error code
