Hello, I have a Hot Springs, Hot Spot, Trinidad, 2005 model hot tub. I just replaced the jet pump on it as it was rusted out. The pump works perfectly now on both speeds, the lights work, and the heater is jamming out at 111 degrees, even though the default 102 is what it should be stopping at. I replaced the filter as well. The problem is the display will read like 85 degrees but in measuring the water with an outside probe it reads 111 degrees, and I get 3 blinking lights on the display panel. The heater is obviously working, so I thought maybe it was a faulty temp sensor. The part number is here: http://www.backyardplus.com/proddetail.php?prod=71578 I tested the water at 106 degrees and the resistance on the temp sensor was 5.4K, at 105 degrees it was 5.6K and at 104 degrees it was 5.8K. I have a couple of different charts that shows what the temp/resistance values should be. That is close to a 10K thermistor chart, but how far or close off will show that the sensor is bad? From the chart they should only be about 100 ohms different for each degree. From a price stand point I was hoping it was a bad sensor. Any ideas on what this problem is please? Thanks in advance if you can help!
