MS Quadrupole Temperature unreasonably high, stays high

[ladyc86]

I was wondering if anyone had any insight on this. The MS Quad temperature will not decrease to its set point limit. However the ion source temperature is good.
I vented the GC/MS, checked all connections and when I pumped down, the Quad temperature was even higher and had exceeded its limit. The pressure in the vacuum pump reads fine.
Any help will be much appreciated.

Is it an Agilent? Most likely the sensor has died. Check that the sensor wire is OK and the insulation is intact.

I agree with Steve. If it is an Agilent, the temperature sensor wires will the the ones with the white cloth covering running to the Quads, the wires the power the heater should have the green beads for insulation on them.

Hello dear experts! I was so looking forward to new members and directing the attention from everyone. Thank you very much.
I have problems with parts Auto tune in ion trap 240 GC / MS. Look forward to the suggestions from everyone.
Here is the error when performing Auto tune.
