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
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
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??
