Answers - mend, repair, fix
Had the same problem on our gas 110 and fixed it for a short time but then the clock gave up completely and so no ovens. I purchased a new clock from espares for £64 including VAT and delivery. You can change the clock in about 1 hour from scratch or twenty minutes once you have done it the first time!. Disconnect from gas and electrics and get to back of cooker. Remove vent that goes along back, there are two screws that fix to the frame and four that fix to the hotplates, you will need to raise the glass to access these. Remove all the control knobs and burners/pan supports and the screws under the control panel - note that the screws holding the clock are metric thread not self tappers. Take the screws out of the left and right hand hotplate trays. You can now lift up the left hand tray. !!Be careful!! you only need to lift it about an inch and then back a couple of inches to reveal the screws on the top of the control panel, if you lift it too high you can break off the ignition wires. Lift the right hand hotplate tray on the left side and slide to the right, you can now move it back to reveal the control panel screws. Take these out and the panel can come forward. I supported it on the grill door and right hand oven door whilst I accessed the timer. Make a note of which coloured wires go where - take a picture with a digital camera to be sure - then remove wires and replace. Fit the retaining screws for the clock before putting the control panel back. Reverse the process for re-assembly. If you contact espares you will need the cooker serial number, which with our cooker was on the frame on the right of the plate warmer drawer when you pulled it out. I think different rangemasters have different clocks depending on age and whether they are electric/gas or dual fuel, but I am not certain of that. I downloaded the 110 Gas users guide which explains how to do it, this is probably available for other fuels.
