Sick YS640

Went my smoker yesterday and and plugged it in, cleaned the burn box, put a hand full of pellets in, buttoned it up and hit START.
after the U26 code and the default temp of 350 popped up, i decreased the temp to 300. It immediately went into the COOL DOWN mode with the bars scrawling from the upper left moving down to the lower right. I watched for the next 45 minutes and the controller never told it to go to the HEAT UP mode. Help !!!
