    Troubleshooting a Intertherm Furnace
    I have an Intertherm furnace model mmha056aahr05. Glow plug lights burner starts then shuts down. 3 blinking lights on the code says gas valve error or false flame sensed. Any ideas on problem solving or where can I get a manual
    Thank You

    Clean flame sensor with steel wool or sand paper.
