THANK YOU! You helped me restore heat to my house just as hurricane Sandy is hurtling towards us. I scanned the internet looking for ways to solve this problem. After over an hour of educating myself on how to troubleshoot/repair I went up into my attic with all a number of tools, WD40 and my voltmeter. The one "tool" that solved the problem was a paper clip. I didn't see any blockages but after removing the tube and then sticking a paper clip in the tiny hole of the blue valve of the pressure switch, I was back in business.
Now I'm just a bit concerned and want to make sure that I didn't possibly hurt the pressure switch and put it into a permanent on mode by pushing the paper clip in until it stopped. I'd sleep a bit easier if someone could confirm that one can't hurt the switch in this manner.
On another note, I did see some bug carcases behind the glass porthole before the burners. Should I be concerned about them?
