Hi All,
Thank you in advance for your help.
In the fall we moved into a house with a 2016 installed Sta Rite max E therm 400 gas heater. It worked fine initially, but the would shut down intermittently and the service heater lite would come on. Turing power of and back on would usually get it going again. Last week, it threw a AFS light. I checked the tubing and blew into tube confirming function with voltmeter. I’ve had no further AFS codes. But then it began to have erratic temp readings jumping around. If the temp jumped below what set temp we had previously put in, the blower would come on and subsequently infinite, but the temp would then jump up and it would shut down.(I guess appropriately for what it thoughtbthe temp was)
I replaced the Thermistor thinking that was the issue( old thermistor had some pitting and corrosion) Immediately after I replaced it, the unit clicked and threw an E 01 code on the membrane read out. It would then not startup, or show anything except the E01. I checked all connections.... good.
The under side of the control board red LED 7 and 11 are lit. I powered down, turned off breaker.... then powered back up .... got the usual 126 then R13, then click and E01.
From what I’ve read , E01 is open circuit to thermistor.
The wiring looks good and the thermistor is new.
Could it be the control board?
I stopped by the pool shop and the guy there said he would just start replacing parts if he came out....
Thoughts?
