Not sure if it was like that before and it's normal.. I never looked into it before it became a problem..
The VDR is in series with the DGS coil. The thermistor in series
with the AC feeding the bridge. If the thermistor opens ALL the
current for B+ goes through the coil & VDR thus burning the VDR.
The thermistor normally goes to zero ohms when hot ( very fast).
When jumped the VDR shouldnt heat up at all.
BTW most newer sets just use a thermistor that OPENS when hot.
No VDR used, its all in series.
Also some use a DGS relay that closes for a short time so it
will DGS runs on every turn on. Some old sets also used a relay ( Admiral ).
