Hello all. I’ve been reading this forum since before we Purchased the Serenity 12327. I have learned a lot from all of you. Thanks in advance for your knowledge and for past things I’ve learned... The Serenity fires up just great. It will run for about 18 minutes. Of course at that point the alarm light comes on and the stove shuts down. “Ignite Fail”. I did switch the wires on the pof switches. I have even put the jumper between the wires. I put a jumper on the other side also, I believe it to be the vac switch. Nothing works. In diagnostics, it tells me that there is an NTC2 error. Does anyone know what that may be? Once again, thank you.
