TEGA (Thermal Evolved Gas Analyzer), an apparent problem

Hello,

According to the publication here:
http://www.space.com/missionlaunches/08053...ion-update.html


The glitch seems to be a short circuit in a filament in a part of the instrument that ionizes the vapors before they are sent to the detector...

Does that mean that it's directly related to the DSC oven?
