My gas furnace is blowing cold air some of the time. The burner kicks in for about 10 seconds...


then kicks off, then the fan starts.(blowing cold air). Some times it works properly, heating longer and keeping the temperature up. Other times the temperature can drop down lower than the setting, then finally it realizes it's too cold and then works again. Any ideas? thx
