Im having issues with buttons not working on my 5660 panel. It's been an intermittent issue. After the startup mode completes it will seem to get stuck in thermostat mode won't allow me to change into manual mode or adjust fan speed or heat level. Only fix seems to be to shut the stove down and try again. Would only permanent fix be replacing the panel? ? This would be the second panel I have installed on this stove, first time the auger motor wouldn't shut off. Are they any updated or aftermarket panels for this stove?? Thanks
