Hi I'm Wayne
I will try to help you with this
did it sounds like a high pitch Squeal?
Let me know
Yes. Like letting the air out of a balloon but much louder.
Thank you for that
OK, what you are describing is the air drier
is plugged up and malfunction, seen this many times
and yes the heat is a a factor, what is happening the
relief valve is purging air out and sticking open
I suggest to have the drier replaced
I hope this helped you
