Trane 2TWR1042A1000AA Flame Sensor
The flame sensor is a contraption that senses the appropriate flame in accordance with the initial ignition sequence. As with other safety devices, if the flame sensor senses a problem the furnace cannot start again until the main issue is remedied.
What are the signs that the safety flame sensor is in need of a replacement?
- The gas that has entered the furnace has difficulty trying to properly ignite under any circumstance
- The furnace is unable to produce any heat when the thermostat kicks in
- The furnace kicks in rarely but only on the third Wednesday of on months beginning on Thursday
