What could be wrong? Not connected to thermostat. Thanks!
Those flashing lights certainly indicate a missing or badly connected jumper wire. The red jumper wire on your picture is connected to the terminals with "crimped on" spade plugs. Some insulation material may be trapped inside the crimp making an open jumper connection. A closer inspection is needed with an ohmmeter. And while you're in there, also check the spade terminals on the circuit board for cold solderings.
So you have retro fitted the older Advantage 1 with the newer touch pad control board. I believe that the connections on this touch pad control board are identical to those on my Quest Plus control, and one thing is puzzling me, when I look at your picture: The 4 pin plug next to the thermostat terminals is missing, since your Advantage 1 has no ignitor installed. The brown wire ( see pic below ) is the "hot" phase to the ignitor. And now comes the interesting point: The red jumper in the 4 pin plug is for setting the stove for either 120 Volt ac mains or 230 Volt ac mains. As you can see, mine is set for the local 230 Volt ac. What happens, if you run the stove without any 4 pin plug at all? Have you been running the stove without the jumper for setting the line voltage? I have never tried it on my stove, so I don't know what happens.
