I had a new Weil McLain water oil boiler installed in October of 2009. It's been great, I noticed this morning, heat wasnt working, so I went to to check the furnace. the temprature was fine, but the LWCO light was on. I taped the the top of the furnace with my hand, and the light shut off, and the heat turned on. I'm a little confussed whats going on with it
