Where can i find the fuel cut off solenoid?
Not the computer what is going on is that the fuel cut off solenoid when you switch to lp / reg gas either lost its voltage and it not opening and also check the air gap at the top of the mixer head on the throttle body and this!! info comes from a man with 40 years in LP gas installer with a class 10 licence on LP and natural gas servicing and repairs >>ME!
