Rangemaster 110 gas, the clock has stopped working and is stuck on Auto. I have tried resetting, turning off the electric etc but nothing works. On one site I have looked at it recommends lifting the top of the cooker to get to the wires and disconnecting the clock. Have tried this but the right hand side of the top where the griddle and warming plate are will not life. Any suggestions more than welcome. Not in a position to buy a new cooker at the moment. Many thanks
