Hi! www.manualslib.com/…/Zanussi-Zfc19-4d.html Here you can download the manual I didn’t manage to find the relay, I only found one place that has the thermostat: fixpart.co.uk/…/electrolux-aeg-50206930005-thermo… I’m not sure to what degree it helps, but if your problem with acquiring a part is geographical in nature I’m in Ireland, and am happy to get and mail the part for you if it is available in either EU or the UK. Good luck and keep us posted!
