Hi everyone. We are a 2020 3120RL. Our furnace has started cycling on and off frequently, i.e. kicks in, runs 10 seconds then cuts off for 10 seconds, on 10-off-10, and just keeps repeating until it reaches the desired inside temperature (at least we're warm) but its annoying as heck at night. I think I might have replace some kind of heat/ temp sensor or board? Anyone else ever have the same problem? Thanks in advance!!
