Hi I have a hotpoint luce double oven DX1032cxs the grill comes on but wont stay on it just cycles on and offAnd doesn’t get hot enough, I have changed the temp probe and top oven thermostat But it has not cured the fault, I can hear the realy clicking in and out as the grill goes on and off every minute or so.If the oven needs a new circuit board will it need programmingBy hotpoint after fitting ?
