Clock i can not get the clock on the cooker off automatic.

GOOGLE! GOOGLE! GOOGLE!
Chichester gas cooker manual

The first 2 pages on a Google search are nothing but manuals.

Does the "manual" button not do anything in this state?
Have you tried this sequence?:

SETTING THE TIME OF DAY

Step 1 Make sure all oven controls are turned Off.

Step 2 Check the electricity supply to the cooker is turned on.

Step 3 When switched on the display will show 0.00 and the Auto symbol,

flashing intermittently.

Step 4 Press & hold in both the Cook Period & End Time buttons together.

Step 5 With the Cook Period & End Time buttons still held in, press either the "+"

or "-" buttons to set the correct time of day.
Step 6 Release all the buttons simultaneously.

Had a two Jackson topline cookers for the past 31 years I think the timer is on auto that is why the oven is heating up its self. Look at the clock there will be 3 bottons push in the one that is marked auto that should set the oven back to manual for you. Hope that this helps

Hello,

You can set the timer on a range slow cooker to automatically switch to a warming setting when you estimate foods will finish cooking. The programmable features allow you to leave food stewing at home while you are out of the house, freeing up your day.

Set the timer on a range slow cooker to let the kitchen appliance do all the work, and come home to a fully cooked meal.

Fill the insert of the range slow cooker with food and cover it with the lid. At least a quarter of the insert should be filled with liquid to keep the environment moist during long cooking times.

Press the "On/Off" button on the left side of the electronic control panel in the front of the appliance. This will turn on the slow cooker to the low heat "Warm" setting.

Press the "Cook Time" button on the right side of the electronic control panel to add hours to the timer which will show a total time in hours with a red digital display. Continue to press the button until the display indicates the desired cook time in one-hour increments up to 10 hours.
The cooker will automatically adjust the temperature setting based on the amount of time you programmed on the timer. Cooking times of six hours or less automatically start on "High" heat and times of seven hours or more will start on "Low" heat.
A small indicator light will come on below the word to tell you the cooking temperature.

thank and thanks for using fixya.

most likely thermal fuse behind oven take off back plate and you will see the brown wire with the heat shrink sleeving covering the fuse.wire and fuse comes as one part

Remove cooker one elect plug and four screws place it face down the clock can be seen at right top, sqirt Wd 40on bottom right of clock wet the cog wheel then using a match or toothpic apply two matchhead sized amounts of copaslip or graphite grease then plug cooker in for 5 minutes still face down the WD40 will assist the grease to go through the workings unplug refit cooker replug in after about 30 minutes silence mine has now been quite 2 months i also greased bearings on both fans at the same time.

You need to press 2 or more of the timer/clock buttons in seqeunce to cancel the auto setting.
The sequence of buttons varies according to the make of cooker, so just keep pressing the buttons until you hit the correct sequence.
Hope this helps.

Go to menu. Directions for proceeding will start with the hour and then the minute.

Your pressure cooker sounds like the Prestige Automatic Pressure Cooker which I have had for 29 years and is still working. If you go to Google and type Pressure Cooker Centre Australia it should take you to their web site and you can order the cookbook for the aforesaid pressure cooker. Hope this helps, Celia

Comes on like this when switched on, hold down the left 2 buttons on the clock controls then whilst still holding them pres the right hand button
