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.
