CONTROL HEALTH and GAS VALVE; failed to establish main burner after 3 successive attempts
Explanation: The unit will make three attempts for main
burner, then locks out. This is probably associated with
a fuel supply problem.
At a minimum, check the following:
1. Gas valve ON
2. Gas valve connector Molex is firmly seated.
3. Wires to this Molex are firmly seated into the
connection itself.
4. Recycle power by pushing the red button.
