this unit has had a circuit b ( could be "A" , not sure which circuit actually) low sat suc temp alarm for months .
I will not reset . you can reset it thru the controls and it comes back within a few seconds. you can power the machine off ( line voltage ) and it returns instantly.
I have sat and watched the transducer value on the hsio and it never moves . It's in the 50+ degree range .
The machine has tripped alarms on the other circuit and they reset flawlessly.
what gives ?
