Found thermastat gone on left oven. fitted new stat but no neon light on=no heat in oven. all fans come on but no heat. no oven cavity light either. I have worked on one of these before and it had a left hand door microswitch, but this hasn’t. any ideas anyone please. couldn’t find a cavity stat????????
Look for melting of connections{ fan oven element} on oven selector switch, had this last month.

Re: SMEG A2 oven not heating
do you have to take the hob top off? plus will i need a new selector switch please?

Had the same oven 2 weeks ago with the same fault, Turned out to be the t.o.c near the terminal block.

Check the wiring block at the back of the oven(top right hand side looking at it from the back) I’ve done quite a few with melted wires in there.
MervHi, have you had the back off the range. If so was there a circuit board near the mains in block, if there is then it most probably is that. A simple test ok, with the back off have the oven on (any temp will do), with your volt meter first check power to the fan motor (just to check voltage) then check the power to the fan element, if no power it most probably that control pcb. On some of these models they have been sneaky and put this pcb in, power from the stat to a relay on the board and power through relay to heater, similar to the SUK 91 series.
Oh, just another thought, this is a multifunction oven, ie you can select the grill and us it as a conventional oven using top and lower elements. Select the equals sign =, this selects top and lower element, turn stat on and check if the top element becomes hot, if so it may be the selector switch burnt out, can happen, maybe be best to check that first.
Is the timer an oblong one or a dial?, if it’s the oblong one then you can remove the facia, then remove two securing screws on the right & left side (you will notice one by the timer, the other is opposite. You can lift the hob like a car hood, bring down two stays one on each side of the hob and you will notice a V shape at the end of the stays, these stays are located into the box hole for stability. However if you have the dial one (oh dear) you need to remove the rear, you will find two screws holding the top on either side (heads facing towards the back panel) again on opposite sides, these have to be removed prior to the above procedure otherwise you WILL damage the hob, be very, very careful how you lift the hob, the rear may well want to come out of their sockets. This is not for the faint hearted
I hope this helps ROBWASH.OT
Re: SMEG A2 oven not heating
Wow OT this is a mad oven. It has the cicuit board at the bottom of the back. The oven fan has 240v. I tried the other settings and no heat works on grill or static oven settings. Does this mean that it could be the little p.c.b. at the back? cheers big help, Robwash
One final check just to make sure. remove the wires from the relay on the pcb and short together, switch power back on, and set up the fan oven and stat, check voltage at the element. If there is voltage there you know for sure that is the problem.
All the best.
