and also cycles a couple times when it is shutting down. I've read about the fan limit switch but I don't see one in my unit. It draws air from the top of a townhouse so it isn't drawing in cold air if that helps. The pilot lights fine, ignites 2 large flames fine, and then fan kicks on fine, but fan cycles off then on, then off, then on a few times until it stays on.
I can see 2 solenoid switches. One switches on and off versus just turning on. I have no idea, but I wonder if there is a temperature sensor that isn't getting warm enough so when the fan kicks on it thinks it's still too cold and shuts the fan off? Thanks in advance.
edit: I forgot to mention it does have a delay switch on the same circuit board as the solenoid switches so I adjusted that but nothing changed.
