The previous occupants of my recently-bought home left behind an electric oven on which the thermostat doesn't work. It's seen better days & i'd like to replace it with another free-standing electric oven of similar size. However, the on/off switch (control unit?) is located on the opposite wall (kitchen is 2.35m wide). The wiring appears to go into the wall immediately behind the oven &, presumably, across the ceiling & into the opposite wall to connect to the control unit (?). My question is this, can any new oven I buy be easily connected up to the existing wiring or am I looking at having to completely re-model my kitchen just to get a new oven?
