Done from about 10:09-10:12. We'll try to fix it in the base.
P.S. In the base, Tom pulled this sensor apart. I noticed that the negative (blue) side of the thermopile was electrically connected to the outer conductive ring of the sensor disk due to a misplaced solder blob. I heated this connection with a soldering iron and removed this contact. Now there is no connection (infinite resistance) between this contact and the ring. We'll replace it at far.
