The 63-10710 was THE DGS thermistor for years in Zeniths.
We got them 25 at a time & they also went in many other sets.
No harm in changing it, they always fall apart when old anyways.
As far as purity goes if you move the set much & turn it back on HOT
it will often be off. You DO NOT have to re do it because you
moved it. Just a manual DGS at most, the set will clear itself after a few cold starts anyhows........
