Why does my dryer have no heat even though the drum is turning?

For electric dryers, the most likely cause is a blown household fuse or tripped circuit breaker — electric dryers use 2 fuses or circuit breakers, and you should replace both fuses or reset the breaker. If the problem continues, contact a qualified electrician, as electric dryers require a 240-volt power supply. For gas dryers, check that the supply line valve is fully open. (Page 11)
