How to troubleshoot common Continental furnace problems

Here are some typical furnace problems you might run into, and what to do about them.

• Won’t turn on. 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-off switch is turned on.
  
  Low air flow can also prevent a gas furnace from working, so check the air filter and replace the filter if It’s clogged with lint.
  
  Check the pilot light if your gas furnace uses one to ignite the gas. Light the pilot if it’s out.
• Lack of air flow through the vents. A clogged air filter can prevent air from flowing through the vents, so replace the air filter if it’s clogged.
  
  If the filter isn’t clogged, a problem with the blower fan may be causing low air flow through the vents.
• Makes a lot of noise. Bearings in the blower fan can make loud squealing or screeching noise when the furnace runs. Replace the blower fan if its bearings make noise while the fan runs.

• 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.
• Air filter. The air filter is located at the intake of the blower assembly. It removes dust and debris from intake air.
• 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.
• 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.
• Hot surface igniter. The hot surface igniter is a small ceramic ignition device that lights the burner flame when the furnace turns on.
