Rangemaster U109300 - 01 manual Power failure, Food is cooking too slowly, too quickly, or burning

Power failure

In the event of a failure in the electrical supply the hotplate may be lit using a match.

Food is cooking too slowly, too quickly, or burning

Cooking times may differ from your previous oven. Check that you are using the recommended temperatures and shelf positions. See the oven cooking guide. The oven control settings and cooking times are intended to be used only as a guide. Individual tastes may require the temperature to be altered either way, to get the results you want. Try cooking at a higher temperature setting.

The oven is not cooking evenly

Do not use a tin or baking tray larger than 340mm x 340mm in the Main oven or 232mm x 321mm in the Tall oven.

If you are cooking a large item, be prepared to turn it round during cooking.

If two shelves are used, check that space has been left for the heat to circulate. When a baking tray is put into the oven, make sure it is placed centrally on the shelf.

Check that the door seal is not damaged and that the door catch is adjusted so that the door is held firmly against the seal.

A dish of water when placed on the shelf should be the same depth all over. (For example, if it is deeper at the back, then the back of the cooker should be raised up or the front lowered). If the cooker is not level arrange for your supplier to level it for you.

Oven temperature getting hotter as the cooker gets older

If turning the knob down has not worked or only worked for a short time then you may need a new thermostat. This should be fitted by a service person.

The oven light is not working

The bulb has probably blown. You can buy a replacement bulb (which is not covered under the guarantee) from a good electrical shop. Ask for an Edison screw fitting 15w 240v lamp, FOR OVENS. It must be a special bulb, heat resistant to 300 °C. See the HELP leaflet for spares by mail order.

Turn off the power supply.

Make sure the oven is cool. Open the oven door and remove the oven shelves.

Unscrew the bulb cover by turning anticlockwise. It may be very stiff.

Taking care to protect your fingers in case the bulb should shatter, unscrew the old bulb.

Screw in the new bulb, screw back the bulb cover. Turn on the electricity supply and check that the bulb now lights.

Hotplate ignition or hotplate burners faulty

Is the power on? Is the clock illuminated? If not there maybe something wrong with the power supply. See ‘power supply’ section further on.

Are the sparker (ignition electrode) or burner slots blocked by debris?

Is the burner trim correctly located? Are the burner caps correctly located? See the section entitled ‘Cleaning’

Hotplate burners will not light

Make sure that the burner parts have been replaced correctly after wiping or removing for cleaning. Check that there is not a problem with your gas supply. You can do this by making sure that other gas appliances you may have are working.

Do the burners spark when you push the button? If not check the power is on - is the clock illuminated?
