To remove the flame sensor from a 1988 gas furnace, first, turn off the power and gas supply to the furnace for safety. Locate the flame sensor, which is typically a thin metal rod near the burner assembly. Use a wrench or screwdriver to unscrew the mounting bracket or nut holding the sensor in place, then gently pull it out. Be careful not to damage any wiring connected to the sensor.
Its not a flamesensor its a pilot generater it generates a small amound of electricity to open the main valve that way if your pilot light goes out it wont let gas escape and couse a potentian explosion The above answer is not accurate unless you have a standing pilot model furnace. Then the "flame sensor is called a thermocouple, much different than the flame sensors used in Direct Spark Ignition, hot-surface and intermitant ignition furnaces. The flame sensor uses the flame of the main burner to prove flame at the circuit board by measuring conductivity to ground through the flame.
The pilot flame is/should be about 1.5" long, the diameter of a pencil. When the burners are going, the gas is shot into the burner manifold, and the gas sent to the burner is designed to go to the back of the heat exchanger. So, in a typical 80,000 input heater, about 14"-18" long.
Check the error code on the control board at the furnace. It could be a number of things. If the furnace is not lighting, it could be the ignitor If the furnace lights then goes out right away, it could be the flame sensor If the furnace lights then goes out after several minutes, it is a limit switch. Turn the tstat fan switch to on and see if the fan comes on, if it does not you have no power to the furnace, check the breakers or cutoff switch.
The flame sensor for the model 398AAW036080D is typically located near the burner assembly. It is positioned to detect the flame produced by the burners, often mounted on or near the combustion chamber. For specific installation details, it's best to consult the manufacturer’s manual or a qualified technician, as the exact location may vary slightly depending on the specific configuration of the unit.
The flame sensor is typically located near the burner assembly in gas-fired appliances, such as furnaces, water heaters, or boilers. Its position allows it to effectively detect the presence of a flame during operation. In most setups, it is mounted in a way that it can directly "see" the flame, ensuring proper safety and functioning of the heating system. Always refer to the specific appliance's manual for the exact location, as it can vary by model.
