Ok i tried to measure it on the boards obviously. It seems to be a Varister not a resister... google search suggests it should be removed to read correctly. my meter reads at 200 or 2000 and at the 2000 settings it is showing variable resistance but seems to favor around .400 to .500 but it does move around a lot.
