NateStreeter Posted December 22, 2017 Report Share Posted December 22, 2017 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? https://www.dropbox.com/s/lgn7630cx9osmhs/2017-12-21 21.55.46.jpg?dl=0 Quote Link to comment Share on other sites More sharing options...
Dan.The.Spa.Man Posted December 23, 2017 Report Share Posted December 23, 2017 Yeah it looks like the white heater wire may have been loose or not fully inserted into H2 terminal. Quote Link to comment Share on other sites More sharing options...
Jersey Hot Tub Repair Posted December 30, 2017 Report Share Posted December 30, 2017 I don't know that I'd blame the electrician, but your heater relay board is definitely fried. The problem is the terminal block is too small for the wires. They have a terminal that's probably designed to connect a 12 gauge wire and tell you to hook up the hot tub with 8 or 10 gauge wire. The wires from their heaters are also too fat for the connectors. They make both parts, why wouldn't they make them fit? That's a design issue more than anything else. That's why those boards fail so frequently. Notice how the design allows the power board to get damaged without hurting the logic circuit board? It's almost like their engineers and sales people worked together to come up with a way to ensure repair income stream without getting stuck for a lot of warranty repairs on the main circuit board, which is 4 times the price.
