Spot on Nino, the Varistor is missing completely ! there is a small wire remaining on one of the lugs where it was cut and never replaced. Gee whizz

Opened IJ and half a correct looking picture.

Manual lists 2 different Varistors pointing at the same component, a Metox 10A and 275V 15J.
Jaycar show 275v but not 15J, lowest is 60J? safer to go which direction?

Thermistor 8A 5R25 from manual, no exact match that I can see. All the different specs making my eyes crossed
