I'm sorry it's an electric dryer and sounds like a bearing possibly failing.
it does it when you start the dryer for the first 1-2 minutes and stops!
it doesn't stop at all it continues to dry the clothes fine. It just makes the noise for the first minute or two.
yes you can restart it but I don't need to because it keeps drying without the noise.
okay I see and it keeps running, alright you need to replace your drum support wheels. these sqeal until the warm up after running a few minutes. heres a link to order them, you will need two. http://www.repairclinic.com/PartDetail/Drum-Roller/12001541/400518?modelNumber=LDE7304ACE?RCAID=1000065 thers a video there to show you how to replace them also.
