I have replaced the rotary start switch WE4M519 but dryer still will not start. Is there something else that need to be replaced?
With the dryer not starting you will want to test the door switch and the thermal fuse to make sure that they have continuity. If both these test ok then test for power at the motor and if there is power then the motor is faulty.
I ordered a new start switch. It has 3 contacts and my old switch has 4. Can I just leave the signal wire disconnected from the start switch or do I need to order another part? I cannot seem to find a switch for my model with 4 contacts.
Answer Hello Ava,
The wiring diagram for this model shows 3 terminals only. They are labeled 2, 3, and 4. The double red wire goes to the number 2 terminal, the brown wire from the high limit thermostat goes to the number 4 terminal, and the brown wire from the idler spring switch goes to the number 3 terminal.
how much voltage and/or amperage runs through the dryer startup rotary switch that turns on the dryer?
When you push the start switch there will be 120 vac going through the switch if you were to check it to ground.
