Went out to hot tub running, but no heat. Recently replaced heater, been running fine for a few months.
See picture below. Thank God house didn't burn down!
Thinking maybe electrician didn't hook these up very well, as it looks like maybe that's what caused this?
This doesn't look like the normal relay burned out normal problems, does it?
