    Confused Gas Burner Cycling

    I Have A Janitrol Hi-eff Mod# Gdp075-3 Installed New In 1990. The Burners Cycle Up And Down Rapidly While Starting The Heating Cycle. The Pilot Light Is Steady On The Flame Sensor Wire While This Is Occurring. It Happens Sporadically, But When It Does You Can Hear The Static From Contacts Opening And Closing In My Computer Speakers. Believe It Or Not, That Is How I Discovered The Problem.
    Any Ideas? Thanks For Your Help.

    Is the gas valve loosing power? If so find out where the signal is cutting out. If this model has a smartvalve, then that is likely the issue. They have problems with the internal solder joints.

    Thanks for the education. Since the last post, some other interesting symptoms came up that I will need to have a more qualified tech look at.
