i bought a manufactured home new 1 yr. ago the furnace worked great the first yr. now it will come on and heat up but the vent safety switch keeps opening befor the furnace cycles off and the inducer and blower run continuiosly. i have checked and cleaned both the exhaust vent and intake vent checked all switches and cant find a reason why it keeps opening. when it opens i have to turn the power off reset the switch and turn it back on. then it just reopens. HELP!!!

Check for a obstruction in the vent/exhaust gas line.
God, grant me the serenity
to accept the things I cannot change;
the courage to change the things I can;
and the wisdom to know the difference.
