Well I couldn't do much with stove ( broke my arm) I continued to run stove with 1 igniter ( I know my bad).stove ran great but it finally quit running, both igniters are not working . I'm thinking daughter board and igniters are bad , fuses seem ok , notice number 2 light is really dim .

You can use a ohm meter to see if the igniters are bad. If so you can still start the stove by putting some pellets in the pot and then remove the ash drawer and using a small butane torch apply the flame from the bottom. That will get it started then shut the ash drawer and it should work.
The other choice would be to remove the board and mail it in to get repaired. I would suggest contacting "Blume" who has the best igniters at a reasonable price and he can also get the board repaired or updated if that is needed.
