Furnaces are often uncomplicated and relatively easy to keep up. The purpose of systematic maintenance is effective operation. Whatever kind of furnace that is heating the house, there are several steps to take to preserve the heating in prime operating condition.
Three Components of Heating System
When a heating system does not work correctly, one of the three workings, the source of heat, the circulation system or the thermostat, may be the cause of the problem. IF the furnace will not run, the issue is most likely at the heat source. Possible causes could include loss of power, fuel not reaching the unit or failure of the oil or gas to ignite. If the furnace does turn on, but the warmed air does not spread to the rooms, the difficulty could be in the blower. A defective thermostat will stop the heating system from turning on or could make the furnace turn on and off.
Initial Steps to Furnace Maintenance
There are initial steps to take to work on a furnace. Be certain that the heating unit is receiving power by checking for fuses that are blown or circuit breakers that are tripped at the main panel. Check the reset button which is close to the motor housing. If the motor has been running, wait 30 minutes for the motor to cool down and then press the button one time. If the unit doesn’t start this time, wait another 30 minutes and press the reset button again. Try one more time if necessary. If the furnace has a different power switch, turn the switch on. Set the thermostat at the proper temperature. If the furnace is powered by gas, inspect the gas source to be certain it is turned on and the pilot light is burning. Double check for a sufficient supply of oil.
