Tips that can save you a heating service call:
1. When you feel your house is cold and the furnace won’t run, check the Thermostat( Heat Switch on the wall) and set the target temperature above the room temperature,showing on thermostat and either wait a couple of minutes or check and observe the furnace whether it started firing and furnace blower came on after a minute or two.
2. If the first trick did not work, check power switch in or outside of the furnace room, high on the wall, or somewhere around the furnace, to make sure it is on ON position. If it does not have marking, turn up or down and observe the furnace.
3.If it still did not work. after a couple of minutes, from a distance check for pilot flame on older furnace (not all furnaces have standing pilot burner) whether there exist a pilot flame and gas valve knob is pointing to ON position. If the pilot is out and you are handy enough and want to relight the pilot burner, it is advised that, you turn the Power Switch to Furnace to OFF position before attempting to relight the the pilot light .After relighting the pilot, turn the gas valve knob to ON position and turn the furnace power switch to On position. Please stay away from furnace before furnace start firing, as some old furnaces have scary firing pattern specially when pilot flame is too small to lit the main burners immediately.
