How to Reset the High Temperature Limit Switch On Your Heater
As per CSA and ULc requirements, our electric heaters all have a high temperature limit switch in the base of the heater. If you press the ON button on your sauna, hear the click on the rear wall but no heat comes from the heater, this is the likely culprit. Before resetting the heater with the below instructions, it’s best to figure out why the heater tripped in the first place. A couple reasons why the temperature limit switch will trip are:
- The temperature sensor is not mounted above the heater on the rear wall. If the temp sensor is in the wrong location (ie: under a bench or on the front wall) then the heater can get too hot trying to achieve it’s target temperature.
- The rocks are packed too tightly on the heater. If the heat can’t escape from the heater than the base of the heater can reach the high limit trigger temperature. If this is the issue, move the rocks slightly so they aren’t packed as tightly (make sure they’re cool before moving them)
- The ventilation hole on the bottom, rear wall is blocked. Sometimes snow can block this vent hole. It’s important to keep it clear so that cool, fresh air can be pulled in near the heater’s base.
Once you have determined what caused the heater to trip, please proceed with the below instructions to reset the heater’s temperature switch.
