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.
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.

It should have come with the furnace and if not try Google or RHEEM.com
Remove the wheel, caliper, and rotor (you may also have to remove the wheel bearings depending on the specific model). The wheel speed sensor is attached to the end of the wire facing the wheel hub.
The pressure switch that tells the furnace the vent fan has started and is running properly, did not close. Try tapping it lightly with a finger once the fan has started, then get it replaced. Follow the rubber hose from the vent fan to locate the pressure switch.
Mine is a 1994.
