I am at a loss... I am fairly handy but pool equipment is certainly not a strength. My pool repair company is not responding and I use the spa daily - so I am trying to get the heater to run in their absence. Parts may be an adventure this close to year-end but I have to get thru the first problem first...
My MasterTemp heater decided to start playing games the other morning. The spa was heating up to 101 from the low 60's and it stopped heating at 93. I tried to turn off the heater but the iAqualink said that it was in cool-down mode (it wasn't) so I had to turn it off by putting it in Service Mode and then cycling it to Automatic.
I tried to re-start the process but the heater would not turn on. I did not see any error messages. The Heat LED does come on as well as the Set Temp display.
I tried again later in the day... it heated the spa up from the 80s and again stopped at 93.
I thought the 93 was a odd place to stop consistently so I upped the heat limit to 104 and re-started it (by putting it in Service Mode and taking it back to Automatic). This time it heated to 96 degrees - so the limit went up 3 degrees and the heater stopped 3 degrees higher.
Noticed the heater display was reporting 101 degrees (set point maximum) while the IAquaLink (and the real water temp in the spa) was reporting 93
I am really not comfortable getting into the bowels of this thing (gas goes boom) but I can/will swap out parts. My thinking is that it is not a pressure issue as it hits the same temp each time, not the high limit switch for the same reason (plus adding 3 degrees to the limit resulted in the water being 3 degrees warmer). My guessing leads to the thermistor or the circuit board is causing the heater to see a higher than real temperature.
Thoughts and better reasoning than I have laid out would be appreciated!
