Mine does this when it is cold - in 40s. Display shows 32. Started after replacing an open Balboa temperature sensor. My pump will come on, the heater relay will close, heater will draw current, then relay will open , heater will go off, then pump will go off. Then all this repeats. Only when it is cold. Water temperature is near 95 where it stays unless we want to use it. Then we turn it up to 104 to heat it up. Craziest operation I've ever seen. The old temp sensor was open and heating to some high limit shut off - 108-112. Now it starts and stops when ambient is low.

Is it cold outside? What does the display say? Mine does that when it gets cold. Display shows 32. Mine has some kind of fault which began after I replaced the Balboa temperature sensor. Sometimes it will not allow any changes on the set temperature until the ambient temperature rises a bit (50F).

I think that your simply running the 2 pumps, 10 horsepower unit with heaters on long enough to be near the trip point running amps. Have someone check the amp draw during the time of long usage when cold. You may need to change to the 60amp breaker GFCI package over the 50.

This issue is still unfixed. I just do not understand the display showing 32 and the pump coming on ~every 30 seconds for 1 second. Also, the display will go to 33 then 34 just after the pump shuts off and then after several seconds change back to 32 just b4 the pump comes back on. This process repeats until the daytime temp gets up higher. It's like some kind of freeze protection circuit is haywire. The display will show set temperature if I press one of the change buttons (up or down change). The set temp is within 1 degree of the water temp. Right now that is 98F.

I recently replaced the temp sensor on my spa - part #9920-400262 which was a sub for my 5-60-7014. The only difference I noticed with the sub was that the middle wire was green not white as on the original. The spa is now holding temperature but does the most unusual thing. The display will read 32F on mornings when the temperature is 50F and the spa pump will cycle every 20 seconds for just 1 second. I measured the resistance of the green/black pins of the sensor and get 7K ohms when water temp is 92F. All other pins read infinity (open).
Any suggestions would be helpful.

I want to test the regulation probe/temp probe on my 8 year old Oceanside Morgan Spa. My unit randomly and intermittently overheats to about 108 degrees. Most often the display will be reading 108 also. If I sit and watch it, the display will blink entirely random values - 32, 76, 92 and so on. I've noticed that any time those values are not 108, the heater comes on. I tried cleaning the connector pins at the spa pack to no avail. I took the probe out (pn 5-60-7014). The connector has 3 wires on a 4 pin molex - black, white, red wires. It seems now to be open between all wires. It did not b4 I removed it but I did not write down the readings while at 108. Is there a chart or graph somewhere that gives ohm readings vs temperature of the probe?
It might be the same one as this but my white wire is green on this one

Only if your wire run is less than 10 feet. 8 gauge is designed to handle 40 amps. Google wire sizing chaart.
