Do Gas oven thermostats "drift" over a period of time? We have a combination two oven cooker - my missus swears that the top oven gets too hot (cf Gas Mark setting) and bottom oven doesn't get hot enough.
Is there any adjustment that can be made on thermostat?
Alternatively anyone recommend a digital readout thermometer with a probe which could be permanently installed (one per oven) - (thermometers to be wall mounted behind oven if poss).
