My furnace tripped off for the second time this morning so far. I suspect it is tripping on low gas pressure. We are third from the end on our branch. When everyone is demanding and then our water heater kicks on, I suspect the furnace pressure drops below safety set point. Kicking myself because I didn’t have the patience to wait for it to reset itself. I pulled the access panel, thus opening that safety switch so it reset when I put the panel back. It’s a condensing Lennox 19 years old. When we first moved in it tripped off on low gas pressure until our meter/regulator got adjusted.
The Lennox at my old house had flame sensor issues. About once per winter I would have to pull the sensor and use fine grit sandpaper to clean it.
Good point, I haven’t cleaned that in a while. Suspicious to me though that it’s happening on the coldest day and the water heater next to the furnace is running.
