Low line voltage

The tumble motor lives on 120 volts but the heater needs the full 240, so a machine that spins yet never warms is the classic sign that one of the two hot legs has gone missing
At the panel, throw the dryer double-pole breaker hard OFF and back ON as one motion; a breaker can look seated while one internal pole has quietly let go and is passing only half the supply
Meter the receptacle leg-to-leg for the full two-forty and each leg to neutral for one-twenty — a good leg and a dead leg is the fingerprint of this fault and points straight at the breaker or a lug
Kill the power and snug every screw the current passes through: the two hot lugs at the outlet, the breaker terminals, and the three or four studs on the dryer terminal block, where heat works connections loose over years
Pro Diagnostic Tip
Zero in on the split-supply symptom: the drum turning happily while the clothes stay cold tells you the 120-volt motor circuit is fine and one of the 240-volt heater legs is gone. That reframes the whole job as a supply hunt — breaker pole, outlet lug, cord, terminal block — and steers you away from tearing into a heater element that is almost certainly innocent.
