Oven will not ignite

Replace the timer

Take the tiny screws of there are loads down right hand side then release screws on hob once you can lift hob plates up. Undo the covers on back of timer clock control . Make sure you un plug from mains . Take the neutral of back of timer clock. This will allow your oven to auto ignite again

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

I know the answer. You ,must set the clock else the oven(s) wont work.

Try pressing the stop/cancel button, this should clear the error, if this does not work unplug for 5 minutes and then plug back up , this should clear the display and the oven should work.

Hold down the 2 left buttons together, and press the + or - button at the same time..
This should reset the timer.

The E1- F5 error is a door lock error.

The control (TIMER) has likely failed in this instance - BUT...

Sometimes when you disconnect power to a range and reconnect it the electronic range control gets confused.
You should disconnect power again for 15 seconds and reconnect and see if that helps.

If it doesn't cure the E1- F5 error hold the bake button in until E0- F2 appears in the display.
This is the error for a stuck button on the keypad and is the way to clear the memory of the electronic range control.

Sometimes these work, but if the control has failed it won't make any difference.

If your oven has timer and it is flashing AUTO then you need to reset it to manual for it to work.
If no timer then it could be a faulty door micro switch, located at the front left side..\Hope this helps, please leave feed back.
Thanks

Hope this helps with your dual fuel version 3 weeks on and working perfectly! Rangemaster 110. Ovens not lighting due to faulty auto/clock. FIXED! Our clock /timer kept flashing and would not reset
Someone, somewhere on the internet had the solution to my problem but I can't find the link again to thank them! If you don't mind losing the clock/timer auto function this is for you and it's free! Just takes a bit of time.
Basically you need to lift/open up the LH &RH hobs to get at the wires behind the clock. You should see 2 blue(neutral) wires coming directly from the back of the clock. Pull them out and connect together - should be easy to click them together. Then the ovens will light - but you will lose the auto/clock/timer functions. We only used the timer so not a big issue. We didn't take the control panel off but we did take ages to unscrew the hobs etc Probably took us about 2 hours going back to instruction manual we found on internet and trying to work it out but I think we've saved a lot in not replacing the unit with the usual call out charges. We made sure electrical supply was switched off and just took our time. Really chuffed!

This should allow you to see the instruction manual for the 110. There was another one somewhere showing a diagram of how to link the 2 blue wires at the back of the clock but I can't find it again! By the way our cooker is 10 years old so maybe different from newer models. We didn't have to take of the front control panel we accessed everything by lifting up the hobs to get behind the clock/timer.

Hope this helps! Ovens still working just got to go and buy a wee timer.

hi there switch your oven off at the mains switch for one minute thenswitch back on and set the time this will disable the auto on the timer.
