tefal actifry?

Hi all, Our actify main fan has stopped and NO heater either, stripped down, checked all the usual onboard fuses all good, I have around 130v either side of the main fan on the brushes leads but fan is not working, does it sense the fan is working and then switch the heater on or is it not that clever ? I have continuity on/across the heater leads so I assume that's ok. Do you think my issue is the fan or the pcb ?? I have no heater voltage output from the board (switched via the relay, I assume) but the relay clicks at off so is contacting. ANY THOUGHTS anyone ??
