Weather maker 9200 wierd heating problem

I have a weather maker 9200 and ever since we had that warm spell 3 days ago my furnace errors 31. However if I disconnect the the tube or pinch the tube leading into where the 3 burners are, the 31 error goes away and the furnace lights and works until the next time it calls for heat.

Prior to this issue I had replaced my thermostat with a nest and it worked fine for a week.
