TAC 20 Viscosity Control

Believe I have a bad up to temp sensor.
Do i have to pump all the oil out to get to it or is there some trick.

Then I only noted a "open on rise" @ 100 degree device from Component Source.
Does this sound about right?

Any comments?

I believe you located the correct low temp thermostat.

On submersible unit, it should be bolted to the crossbar motor mount above the motor. Unless you have a lot of extra oil, it should be only a few inches below the oil line with elevator at top floor.

Thanks man
