Apex temp fluctuations

[Kyle1970]

Normally tank is good but temp seems to be fluctuating all over as of yesterday afternoon.

Bad temp sensor?

House was not hot enough to cause this.
Temperature on Sicce pump was within limits.

Clean the sensor and calibrate it

Thankfully temp probes are cheap. I usually have one spare on hand

That was the cure.
Picked up another spare heater while I was out as well.
