Hello there I am wondering if you can tell me why my dryer is not pushing out no hot air I transfered my clothes over into my dryer this moring and have to keep adding more time onto it cause it dries the clothes it is not doing it though with hot air it is cold. The lint filter also keeps saying it is full but I change it everytime I transfer the clothes over the filter I am not worried about I just want ot know what could be wrong and why I am not getting no hot air I called a repair person and they was gonna charge me like 60 dollars just to come to the house. So what do you think it will run me to fix it roughly I also do not have the manual to it or I would just look it up.

Thank you
LORI
