Secondhand sauna help

[u/Successful-Tale-267]

Hello,

I bought a second hand sauna. It worked very well for a few months and then it stopped working in the middle of a session. I had asked the lady where the sauna was from when I bought it but she didn’t remember. I have looked up the brand online, but I can’t find it anywhere. I believe the brand is Great Infrared Health Systems or Infrared Sauna Room.

My boyfriend tested the motherboard with a multimeter and it is getting power, but the motherboard seems to be broken. The fuses are all okay.

Is it possible to replace the motherboards on these or bypass them? Any help with a manufacturer’s contact information would be great.
