Thanks for the suggestion, I really have no idea what’s going on! It lights fine 90% of the time. The situations where it won’t light the blower comes on and I hear the igniter clicking. It tries 3 times then shuts down. I’ll then turn off the furnace at the thermostat and switch it back on. Then it lights right up. I’ll also note that we’ve never woken up in the morning to a cold coach. The furnace is always running in the early AM!
I really don’t want to pay a tech (or do myself) to just throw parts at it. Because it’s so random I’m guessing it would not happen when the tech is here.
