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.
