the pressure switch connected to combustion blower by 2 hoses ,am i correct for your model,make sure hoses are on correct location,check the little nipple the hose slips on ,these things get plugged with deposits and won,t let pressure switch get the vacuum it needs.suck and blow on the hose as well and get the pressure switch to operate,sometimes they get sticky from sitting over the summer
