Clothes dryer functioning but no hot air

[Squeeealer]

Any ideas of what I should do first?

Thanks!

do you mean the tub turns, but does not heat at all, or some but not much hot air. If no hot air, then you may have an open heating element.

Clean out the vent tubes
That's the first thing to check

just ran into this myself. one breaker was running the dryer as far as turning and another was supplying the power for the heat. the lady at HD said they see it all the time and had me check the other breakers. sure enough!
