NTC 22 for HB810 up to and including HB823 and HP8540

There is one NTC resistor in the base of the Sunmobile for each lamp, three in total. Replace all three if one has cracked!

An NTC ensures that the inrush current is limited when switching on.
When the Sunmobile is on, this resistor becomes very hot.
That is normal. Therefore, ensure it is mounted in such a way that it does not touch the plastic housing, and do not shorten the connecting wires!
