Smeg SUK91MFA5 Cooker

[subs]

This duel fuel cooker has no elements working in the oven.
Both fan, top and bottom and grill elements all check out ok. If you select the fan oven the fans come on and the light to the stat comes on but no heat. Thermal cut out ok. I’m getting power to elements but it seems no neutral. I’m thinking it may be something to do with the small relay board at the back. What is this for?

Any Help Please?

Thanks

Re: Smeg SUK91MFA5 Cooker

its a relay pcb to control the high power fan elements hence allowing the thermostat on the control panel to handle only a low current. part number is 811650197. The best way to check it is to connect a volt meter to the 2 wires between the relays and check you are getting 230v there when the thermostat is turned up, if so, and you cannot hear the relays click then it will be the problem. On some SUK91 this pcb only switches the fan elements while on others it switches all elements.
