Hi, I was hoping someone could help with some advice. I have a Smeg DO10PSS double oven and the main (bottom) oven has decided it will no longer heat above 140 degrees or so. I have tried all the settings with combinations of the various elements and it always warms up to this temperature but no higher. As far as I can tell the elements still seam to be working (i.e. the bottom, rear fan and a combination of the top and bottom).
Could this be a faulty Thermostat or thermocouple and if so are they easy to replace ? This ia a fairly old oven so not sure I want a hefty repair bill for it.
Thanks
Mark
