Hi, welcome to Just Answer. My name is ***** ***** I look forward to helping you! The unit has locked out because the flames have dropped out during a heat cycle. Many things can cause that. If you unplug the unit for a few hours and restart, will it fire up?

7 flashes:

5 flames losses during one heat cycle. Ignition Re-Cycle - The control will re-cycle up to 5 flame losses (4 re-cycles) within a single call for heat before going to lockout. The LED will flash “7” during this lockout.
