Servicing a Gas Furnace

  1. Visually inspect the unit (flue pipe connected, etc.)
  2. Remove and inspect the filter (clean if it is a washable filter or replace with a customer provided filter if it needs replacing and if the H/O has one.
  3. Check the blower assy. And blower motor bearings, lube if required.
  4. Inspect the evaporator coil for cleanliness.
  5. Remove the flame sensor if it has one and clean with a green scrubby pad.
  6. Remove the Pilot assembly and clean the orifice (I use to use a sewing needle or a torch tip cleaner)
  7. Remove the gas manifold if necessary and all the burners, clean the burners with a wire brush. Inspect the gas orifices to ensure none are plugged or have any trash in them.
  8. Visually inspect the heat exchanger for cracks or holes. If you have a heat exchanger brush, Rod out the heat exchanger then vacuum.
  9. Reassemble the burners and manifold and make sure the gas valve is in the on position. 9. 10. Connect your Richey gauge or manometer, turn the gas stop on and check the gas pressure coming into the gas valve (natural gas should be between around 7 inches) and around 3.5 inches coming out of the valve going to the burners.
  1. If it is propane it should be around 14 inches coming in and 11 inches coming out of the valve. You are required by law to be certified for Propane gas meaning you cannot work on propane off another person’s license. You must take the state examine to be certified.
  2. If the unit has a standing pilot you must light the pilot and ensure you have a good strong flame that is surrounding the thermocouple.
  3. Make the t-stat call for heat. Examine the flame before and after the blower comes on, there should be no difference. If the flame is dancing or waving around after the blower comes on you have a cracked heat exchanger.
  4. Disconnect the blower to check the high limit.
  5. Disconnect or pinch off the vacuum tube to the induction motor to check the vacuum switch.
  6. Check the delta T (temp rise)
  7. Wipe the furnace down (clean it with window cleaner or something) and ensure the unit cycles normally.
