Will do on the resolution post.
Don't have the fluke on hand. Bought a Klein MM200 to replcae the GB meter that was not reading amps correctly. Should have bought the MM2000 but did not think I would need true RMS or Low Impedance. Anyway, It's reading 0.074 VAC and 0.5 mVDC between house ground and neutral on control board.

How do I check that?

No luck on the manometer. At this point, everything leads to the new control board being bad. Ordered it online and missed the little note about no returns on circuit boards. I have emailed the manuf. (icm controls)...waiting for a response. Also,the temps have finally dropped to low 40s here in NW Louisiana, so I called the local coleman service tech. The will be here early next week to look at the recall issue. I'll have them figure it out if the manuf. can't/won't help me out.

Flame is blue from tip to toe. Long shot showed 122VAC input with unit off. Lowest reading was 119.5VAC when blower and igniter were running at the same time. Input voltage seems to be ok. Ohmed the sensor & wire. The meter leads have 0.14 ohms of resistance. Testing from board to any joint in wire or tip of sensor gave a reading of 0.30 ohms.

Pulled the gas valve and inspected both ports. I could see the screens in both ports, and they were clean. The flame is blue. Every once in a while, where the flame is interrupted by the igniter or the sensor, there will be some yellow. Spun the sensor in the mount to move it to what looks like it would be more in the flame, but did not help. Checked to make sure the valve is getting 24VAC. I thought that the voltage was droping out on the valve when the blower would come on becuase the valve would shut. However, it shuts even if the blower is not engaged. Should I check the house voltage through a complete cycle (start to code flash) to see if the voltage is changing and causing the valve to shut...long shot?
