Does anybody know what is the small silver cylinder next to the thermal fuse? It is inline with the neutral AC from the handle switch, looks like it could be a diode or possibly a resistor, though it really resembles nothing I have seen before. My inoperable unit shows no continuity through this device either direction, so I presume it is bad….but I have no idea what to replace it with!

This is the thermostat, not the “thermal fuse’’ !!
