Description
The Williams Comfort Products P500472 is an L280 Manual Reset Vent Limit Switch engineered to provide dependable high-temperature protection for vented heating appliances. When flue or vent temperatures exceed the rated threshold, this limit switch interrupts the control circuit and requires a manual reset before the system can resume operation — a critical safety feature that prevents unattended restart after an overheat condition.
Key Features
- L280 vent limit switch rated for high-temperature sensing applications
- Manual reset (M/R) design requires intentional operator intervention after a trip event
- Provides reliable over-temperature protection for vented gas heating systems
- Direct OEM replacement for compatible Williams Comfort Products heaters
- Durable construction built to withstand demanding heating environment conditions
Application
Designed as a genuine OEM replacement part for Williams Comfort Products heating units, the P500472 vent limit switch monitors vent/flue temperatures and shuts down the appliance if unsafe temperature levels are detected. The manual reset requirement ensures a technician inspects and resolves the root cause before the heater is returned to service, enhancing overall system safety.
