Pilot Light Troubleshooting

Adjusting the pilot light flame on a gas furnace is the best place to start, if it appears that your furnace is not getting as hot as it

Step 3

Step 4
Rotate the screw on the pilot light clockwise, and the size of the flame will decrease. Your flame should be a consistent height, and
it should not appear to be flickering.
