How to Replace Infrared Sauna power supply module for under $20 - no power to control panel

My infrared sauna would not power on. I pulled off the top panel to access the power supply/motherboard unit (big grey box). My breaker was on. The outlet had power. I pressed the fuse reset and it didn’t help. I used my voltage tester (see video) to confirm power was passing through the fuse reset to the terminals on the motherboard, and from there to the 12 volt power supply. It was, but it didn’t go from the power supply module back to the motherboard to power the control panels, lights, etc.. I called the sauna manufacturer and they were asking $350 for a replacement power supply/motherboard unit. Expensive. I removed the power supply module and looked up the numbers. It was as not in stock online, but I discovered it was a 72 watt, 12 volt, 6amp switching power supply. I ordered a Mean Well LRS 75-12 6amp unit from my favorite online supplier for under $20 delivered. I disconnected the power by shutting off the breaker for safety. I disconnected the original wires from the power supply (had to cut them) and stripped the ends and re-attached them to the new power supply as labeled on the motherboard: L for load, N for neutral, V+ for 12 volt positive and V- for negative. I switched the breaker back on and the unit powers up again like it used to 👍
