My Kirkland dryer is heating up and tumbling but is not blowing the air out the vents and drying the clothes. I've checked the vents for clogging but still not drying. Do you have any suggestions?

How did you check the vents? Did you pull the hose off the back and try it? If it doesn't blow with the hose off, you have an internal blockage. If it blows, you have an external blockage.

Could also be a bad fan motor.
