Hi my name is ***** ***** I will assist with your query.
Can you advise of the model of Stoves oven, and if you can hear the igniter clicking when you turn it on?
Sorry for the delay.
This would suggest the oven isnt meeting the pre-checks required to ignite.
If your not getting a spark the most likely cause is the gas valve, however will require a gas engineer to attend.
Please provide me with your postcode so I may recommend someone in your area.
Please give me a few minutes, to find a suitable engineer, if you prefer I can call you back with the information.
Due to your proximity to London the cheapest repair option is to use Stoves directly, they charge £139 (paid over 6 months) to repair the oven and that then gives you 6 months warranty for any further issues.
They can be contacted on 0344(###) ###-#### and then selecting option 2.
Appreciate if you can rate the service received so I may resolve your case.
