Replacement heating element for life smart 2 person sauna

My sauna is having the same error, did you find a solution?

What does EP ON THE SAUNA MEAN ?

check to see if filters are clean if so see if recirculation pump is working if so check heater fuses if blown probably bad heater element

When I'm in a traditional sauna like this, I expect the temperature to be between 70 and 90C so that's what I assume you are trying to reach. There could be several reasons for this so make sure each point is checked:
1. Stating the obvious, to increase the temperature inside the sauna, you'll have to ladle water onto the hot sauna stones.
2. Maybe the insulation within your sauna isn't good enough and heat is escaping.
3. Your sauna room could be too big for this heater to heat properly.
4. Maybe the element on the heater isn't performing properly and needs to be replaced.

These were some pointers which Di Vapor gave as possible reasons for lack of heat.

be looking for fuses or connections .. does it have power??

I don't know what a sauna has to do with sewing machines... but I suggest that you locate and test the heating element.

Did you get an answer to your question. I am also looking for s126smd3 to buy.

more than likley installation problem not enough voltage top operate heating element

the 'easy' answer would be a tripped high-limit switch. Inside the generator box, there is a resettable circuit breaker to the heating element, on the top of the water tank.
kill the power to the unit, take off the shell and look for the pushbutton.
If that is the problem, there is a likely chance that the temp sensor in the shower is not working so it overheats and trips the high temp limit.
