The flash is an error code. Count how many times it flashes. And then look the code up. Code legend should be on panel.

Slow back and forth flashing is locked out due to ignition failure 5 times in a row. It will stay in that mode for one hour then attempt to light again.

The hot surface ignitor wouldn't come on if a safety was tripped so you're looking at a gas problem. Could be the control board not sending 24 volts to the valve, a bad valve, gas shut off, spider egg sacks in the orifices ect. How deep you're willing to check before calling for repairs is up to you.

That's part of the gas valve, not a seperate replacable part. Sounds like it's time to buy a new valve if you made sure there's gas coming to the valve but not getting through.
