Have 2 Charmglow model 200605's only 12month old to the day. Both won't lite. Pilot won't lite with or with out match. Electric ignitors seem to work. Had someone out and cleaned entire system and said no bug or spider in pilot venturie etc... Checked and purged all lines. Spent $125 and repair guy said he thinks the control valves are bad. Does this sound correct. The guy did seem to do a good job and was very frustrated but couldn't get anything to lite.
