Bestt to you

If power is reaching the cooker the problem must be inside. If the answer isn't in the instruction manual the only solution will be to follow the circuit inside, checking as you go.

Yes it's possible to disconnect the clock but must be done by a professional repair man

I have a Newhome GL616 oven, is this a self cleaning oven, if so how do you set it to do it?
Thanks

The timer has broken and needs replacing

I had the same problem, we checked all the wires inside and all ok, so phoned stoves and they said that the it sounds like the timer as this is the first port

Replaced the timer and cooker is now working fine - only thing to remember when ordering the timer - my cooker is green and now has a red light instead of green

Hope this helps

Cost of timer from stoves £56.83 inc vat and delivery
