My Bixby Max Fire 110 lights keep blinking. It starts up and runs perfect for roughly 20 minutes to a 1/2 hour and then lights 2 and 3 will blink. There isn’t a pellet jam, the wheel is moving and dropping pellets. The exhaust is new and has an outside air intake. I have cleaned and lubricated the exhaust fan … it runs fine. I also cleaned and lubricated the blower fan and it runs fine. If I switch the feed setting on the panel board up or down..the blinking will stop but resume in about 5 minutes. Sometimes it will shut off on its own but typically resumes. Has anyone else experienced something similar and how did you remedy it? I am running out of ideas. Thank you for your ansers in advance.
