Hope I'm not too far of topic, but maybe someone can help. Just bought a used high end BBQ. After a good power wash I can get everything to work but the infrared rotiss burner. The burner will light, but not get red. No parts are avail for this unit (was in production for 2 yrs). I have not taken it apart yet and don't know if it is a ceramic material or the older woven material type. I have looked on line and found some replacement ceramic squares that might work. Anyone ever take one apart and replace the material?
