The Gas Hi-Limit Switch (High-Limit) is a critical safety component for sauna gas heaters that automatically shuts off the gas valve when the heater reaches an unsafe operating temperature. This thermal safety cutoff protects your sauna from overheating, preventing damage to the heater and reducing fire risk.

The hi-limit switch is a wear item that should be inspected regularly and replaced if your heater is shutting off prematurely or failing to reach operating temperature. This is an OEM-compatible replacement part for standard sauna gas heater models.
