Lots of problems with this cooker . Initially found a flaw in the enamel top, incorrect knobs fitted, grill compartment door warped. Replacement knob for gas oven was for an electric one. Then three months after purchase the gas oven has broken down and we have endless problems with Rangemaster trying to get it replaced. Theiir Customer Service Department is totally incompetent - they don't call back when they say they will, haven't registered what the actual problem is, don't deliver when they say they will, so over Easter when I have visitors I'm without my main oven. The response to everything we suggest is "no", basically they' ve just shrugged their shoulders and ignored us.
