Dryer, no heat nor spin

Our Maytag gas dryer last month used to start with a loud noise and after few seconds will work normally and dry the clothes. Last week, it spin but wont dry due to no heat coming in. Yesterday, I tried it again, since I’m planning to buy coils but found out that it won’t even spin. The only thing I noticed is the noise inside which maybe the motor. Any advise Pros? Thank you for all the help.
