Most common Janitrol furnace parts that need replacing

  1. Thermocouple. The thermocouple or flame sensor is a small metallic device positioned in the flame path of the pilot light. When the pilot flame is lit, the thermocouple sends a signal to the electronic control board or gas valve indicating that the pilot is lit and that it's safe to open the gas valve for flame ignition.
  2. Air filter. The air filter is located at the intake of the blower assembly. It removes dust and debris from intake air.
  3. Blower assembly. The blower assembly is the air handler that circulates air through the heat exchanger in the furnace. It consists of an outer case, a blower motor and blower wheel.
  4. Thermostat. The thermostat is a temperature control device that mounts on a wall inside your home. The thermostat monitors temperature inside your home and tells the furnace when to start and stop.
  5. Hot surface igniter. The hot surface igniter is a small ceramic ignition device that lights the burner flame when the furnace turns on.

How to troubleshoot a Janitrol furnace that won't start

  • Check for electrical power. Check the house circuit breaker for the furnace to make sure it’s turned on. Reset the circuit breaker if it’s tripped.

    Gas furnaces often have a cut-out switch that looks like a regular light switch located on or beside the furnace that shuts off electrical power to the furnace. Make sure that this cut-out switch is turned on.
  • Check the thermostat. Make sure you have the thermostat set correctly. Adjust thermostat settings if necessary. If the thermostat doesn't have power, check its wiring and reconnect any loose wires and repair any broken wires. Replace the thermostat if it isn't working.
  • Examine the electronic control board. Disconnect electrical power to the furnace and check the electronic control board wiring connections. Reconnect any loose wires and repair any broken wires. Check for burn marks on the circuit board and replace the electronic control board if you see burnt spots or melted wires.
  • Check the pilot light. Light the pilot if you don't see a pilot flame. Follow the instructions in your owner's manual for lighting the pilot.
