Trane TCP042F100AB Flame Sensor
The flame sensor is only used on furnaces that burn gas and is one that can sense the correct flame upon ignition. As you could guess, if the flame sensor senses a problem the furnace cannot start again until obstacle is corrected.
What are some indications that my furnace flame sensor is in need of a replacement?
- System runs sometimes only
- The propane or natural gas has a tough time trying to properly ignite and shuts itself off
- The furnace refuses to start whatsoever

HVAC pros may charge higher prices than others so you may want to ask around to acquire the best rate if you do not want to pay too much.
