If I understand correctly, If you perhaps take the timer dial, with the machine off, turn it to time dry 60 minutes, do not start the machine, but check and see if the heater comes on. If it does, you have one of two problems, Either a shorted heating element, or a bad centrifugal switch in your motor. Also, if this is occurring, an on of these two parts have failed, It is extremely dangerous using the machine, until the problem is corrected.
