Troubleshooting Furnace Issues
- Check the furnace on/off switch.
- Check if the furnace door (cover) is securely attached.
- Check the fuse box or circuit breaker.
- Check if room temperature is higher than you have your furnace set.
- Check if the thermostat is in the “heating” position.
- Check the batteries in your digital thermostat.
- Check if the exterior intake vent or exhaust vent are plugged with snow or another object.
- Check to see if you have adequate fuel in your tank.
- Check the furnace filter.
- Check the restart button on the motor (fuel oil).
- Check if the fuel tank has run dry.
- Check if the pilot light is lit? (LP or Natural Gas)
Maintaining Your Furnace
- Check to make sure the pilot light is burning. Some furnace units must be lit by hand if the pilot light goes out.
- Follow the instructions for relighting usually printed on access doors. If you have difficulty relighting the pilot light, call a qualified heating contractor for advice.
- Check the blower and vacuum out and dust or debris in and around the unit. Check or replace the filter every 30 days. A dirty air filter clogs the air flow and it can overwork the equipment.
- Lubricate the blower motor.
- Remove the flame shield and check the burner for corrosion. Check flames with the fan off and on to conform to proper operation.
- Check the flue for gaps or dents and make sure it is venting properly to the outdoors.
- Vacuum all the dust from the air registers around the house.
- Check motion and make sure they are clear of furniture rugs, drapes, etc. to let the air flow freely.
