Hi, I can answer your question, lets handle them one at a time. Click 'accept' when you are satisfied.. or we can get another expert.
Does the burner ignite and operate properly? and all you have is this flashing LED signal... or does the burner also fail to ignite?
hello again... we can do what we can from here to sort out the issue, that may take some back and forth checking etc... if that fails then call a service person.. if you are handy with tools odds are about 80% you can get it going yourself with some guidance.
Look at the burner, and for the spark ignition rod(s) next to the burner... see if you can restart the burner..is there sparking at the rods?
If not, turn off the power and use light sand paper to clean off the rods and try again.
Get back to me.
Hello again, sounds like its time to call a tech.. at least you have something of a hint now.
