Electric Hob ignitor affecting Cooker Hood

[Les471]

Hi, hoping someone may have come across this problem before.

I recently installed two new electric circuits (spurs) for our new Gas Hob and Cooker Hood. The only way there is an electrical connection between them is that both spurs go into the same ring main but using separate junction boxes. This should be fine.

When I press the ignitor on the Hob to light the gas, the control panel on the Cooker Hood starts flashing, weird! This happens whether the Hood is switched on or off. Any ideas what may be causing the problem?

Thanks.

Igniter = spark = big pulse of RF radiation/noise propagating through the air and likely also back into the power lines and then into the electronics in the hood control. Probably need a suppressor on the mains input to the hob (to reduce the RF getting out) and possibly on the input to the hood (to stop any that does get out, getting in.)
