I was trying to turn on the oven and pressed different buttons now the timer is flashing but I can't get the oven to turn on. I've tried turning the power off at the wall but that doesn't work. Help!

Have you turned the timer off? Usually involves pressing a combination of buttons at the same time. If this doesn't work try turning off at the fuse. Wait a min and turn back on.

I have a Teka HA830 oven I held the buttons down but it never resets. Would like to know if its possible to change the computer board, and where can i purchase it online?..

This means it is in auto mode. It must be in manual mode for the oven to work. Turn the oven to ON. Some clocks have 2 or 3 buttons. Press the buttons at the same time/try all different combinations. This might take a few minutes, be patient. When the oven indicator lights the clock is in manual mode.

Turn the oven control on. Now play with the buttons on the electronic timer/clock. Try all different combinations. Trying pressing them at the same time. This may take 5 minutes or more. If the timer is not faulty this will work, be patient. When the oven indicator light comes on the oven is on and the timer is now in manual mode.

It sounds like the oven is not working as the electronic timer is in auto. mode. It must be in maunal mode for manual oven operation. Turn the oven on. Muck around with the buttons on the timer and try all different combinations. This may take 5 minutes or more. When you do hit the manual mode the oven indicator light will come on and the oven will work.

It looks like the clock is on its way out. I would try two things. First, turn the power off at the main switch, leave it off for a few mins and then turn it back on and see if it makes a difference. You may need to do this a couple of times. Secondly, with the power switched off, repeatedly press all the clock buttons one at a time a number of times - there may be a contact that needs cleaning by operation and then see what happens. if you do need a new clock/timer then ask espares for a quote.

Are you trying to reset the timer or the Clock? It's a bit different on each stove, but usually if it's the clock, you press the Clock button TWICE, the time will then begin to flash on and off. then press the + or - sign to increase or decrease the time. When you have gotten to the time you desire, PRESS the Clock button ONCE more. The time will be set, & then you should be all set :).

If it's the KITCHEN TIMER, Press the Kitchen Timer button ONCE, the timer will start flashing. It will usually flash all 0000's. Press the + sign to add minutes, then Press the Timer Button ONCE again, it will be set to the amount of time you added and will beep once the time runs out.

Disclaimer: This instruction is primarily for the General Electric Stove. If you state your specific model, I could be more specific.

It will not work if it is flashing, the timer needs to be reset to manual
If it will not reset, then It sounds like the timer is faulty, try a different combination of buttons when trying to reset it.
Hope this helps.

My son came along and managed to get the clock operating once more by just pressing one of the buttons and turning the knob to set the time. Many thanks for your contact. It was much appreciated. I shall know what to do in case this ever happens again.

Depending on the make of oven, you have to press the buttons in a certain sequence if it is a digital one, try pressing the buttons in sequence, sometimes you have to press 2 together, and a third one at the same time,if it is a anologue timer, then make sure you can see the symbol of a hand in the display.
If you cannot get the timer of auto, then it is probably faulty.
Please rate my solution.
Thanks.
