I think it uses a 10811 OCXO. See if it is warm. If not, perhaps the 'thermal fuse'?

It seems that the DAC has ramped up to the rails, 1048560, and I'm getting an EFC fault. Any tips before I open the unit and start poking around? The oscillator is running and pretty close to 10MHz, I don't have any reference accurate enough to check it. Any trends here, is it the EFC in the oscillator or is it the DAC and following amplifiers?
