Temperature Sensor, Gatsby
Hello, my Gatsby tub was running fine. It erroneously came up with a hi temp error (OHT) and it shut the whole tub down. The water temp was not hot and the error will not reset and the error still says 220 degrees even with cold water. I am thinking this sensor may be the problem or at least where to start. Do you agree? Also I believe it is mounted on the outside of the heater, is this the High Temp Sensor I need?
Thank you, Craig
“OHt” Overheating Condition / Watchdog. The system checks the spa water for temperatures equal to or above 120ºF(48ºC) or the heater enclosure temperature that is equal to or above 125ºF(51ºC). If the spa water temperature is equal to or above 120ºF(48ºC) or the heater enclosure temperature is equal to or above 125ºF(51ºC), the topside control will flash “OHt” - current Water Temp - “OHt” and the entire system will shut down. The “OHt” condition requires a manual reset either by pushing the buttons up/down arrow buttons simultaneously or by turning the main power off and then back on. The heater hi-limit switch cannot reset until the heater enclosure temperature drops below 123ºF(50ºC) or the water temperature in the spa drops below 117ºF(47ºC). This must be repaired by a service technician if the problem persists.
