Overview
Reconnect the vacuum switch to the motherboard and clear safety-circuit faults.
This 2-pin lead wire connects the vacuum pressure switch to the motherboard so the board can confirm the exhaust is drawing. A pinched, burnt or loose lead can cause vacuum errors and shutdowns even when the switch itself is fine. On models with a snap-disc proof of fire sensor, the same wire connects that sensor. Includes one lead wire.
