Sauna Heater & Parts Frequently Asked Questions

It’s usually a "tripped" High-Limit Switch. This is a safety thermal fuse designed to cut power if the heater gets too hot. Most heaters have a small red reset button on the bottom or side. Give it a firm press (you should hear a click). If that doesn't work, check your circuit breaker or the contactor (the heavy-duty relay that clicks when the heater turns on).

Turn the sauna on for about 5 minutes and look at the elements (the metal coils). They should all glow a dull orange. If one remains dark, it’s dead.

It’s almost always poor airflow. This happens if:

Your sauna stones are packed too tightly (suffocating the heater).
The stones have crumbled into small bits over time, blocking the bottom vents.
Your intake vent (usually under the heater) is blocked or non-existent.

Placement is everything. Most manufacturers recommend installing the sensor on the wall directly above the heater, about 2 to 6 inches (5-15 cm) below the ceiling. If it's too high, the heater will shut off too soon; too low, and you might accidentally turn your sauna into a kiln.

"Sn" usually stands for Sensor. It means the control unit has lost the signal from the temperature sensor. This is often caused by a loose wire at the terminal block or a "broken" thermistor inside the sensor probe. Check the tiny wires connecting the sensor to the heater’s main board.

For home use, every 2 to 5 years. Over time, the heat makes the stones brittle. They eventually crack and turn into "pebbles" that block airflow. If you see a pile of sand or small rock shards under your heater, it’s time for a fresh box of rocks.

Yes, but indirectly. You should pour water onto the stones, which then transfer the heat to the water. If your elements are "naked" (visible with no rocks covering them), the thermal shock of cold water hitting red-hot metal can cause the elements to warp or crack. Keep them covered!
