jesusfreak Posted September 7, 2017 Report Share Posted September 7, 2017 I have a 2005 Sundance Cameo hot tub, it was given to me from a friend. When I filled it with water the heater continually is on. I have turned the tub on until it cools off, and once turned back on temp runs up over 104. Any ideas??

Jersey Hot Tub Repair Posted September 9, 2017 Report Share Posted September 9, 2017 If you don't turn the hot tub off, does it shut off automatically when it goes over about 120 degrees? That's when the hi-limit sensor should shut it down. If so, you're heater relay is probably not opening when the temp sensor tells it to, indicating a logic problem on the circuit board. Are you checking the temperature with a thermometer, or depending upon the control panel to tell you the temperature? If so, the temp sensor may be bad and the tub may not be as hot as you think.

jesusfreak Posted September 11, 2017 Author Report Share Posted September 11, 2017 I have not let it run up to 120 degrees...this morning it was flashing OH..108 degress. I have checked the thermostat (16,700 ohms) 104 degress...seems ok. Replaced the High temp sensor prior. Thanks for the response Quote Link to comment Share on other sites More sharing options...
Jersey Hot Tub Repair Posted September 14, 2017 Report Share Posted September 14, 2017 The OH tells you that the hi limit sensor is working properly. Are you going by the control panel temperature readout or by an independent thermometer? If it doesn't shut off at 104, either it doesn't know it's over 104 (indicating a bad temp sensor), or it can't shut off (indicating a problem with the circuit board).

jesusfreak Posted September 14, 2017 Author Report Share Posted September 14, 2017 I am going off of the control panel temp. I checked the thrmostat ohms and according to the spec sheet on internet it is ok.... 16,700 ohms @104 Degrees Quote Link to comment Share on other sites More sharing options...
