I’ve had a search through the first ten pages of Forum issues but little seems like my problem with the Zanussi built-in oven.
Originally, whilst opening the door with the oven just being switched on, there was loud ‘crack’ along with a blue spark at the leading-edge of the upper grill element and the oven remained cold. Suspecting a blown element, I ordered & replaced it, along with a new bulb (which had failed ages ago) and a new door-seal (likewise). Before I replace back-panel & re-fitted the oven, I trialled it by plugging in & switching on.
The LED panel works ok but there is no heat being generated nor is either the light or fan working but the biggest concern is that of a regularly, repeating ‘clicking’ noise somewhere it seems, at the top of the oven.#
May I ask if someone could advise what my next course of action should be please?
Re: Zanussi ZBQ965X … Clicking noise?
Have you set the clock to “manual” ? If you have and the oven still doesn’t function, then it could mean a faulty relay in the clock unit – the clicking would suggest this. When an element fails it can sometimes (unfortunately) blow a relay in the clock. The relay switches the element, the fan motor and the lamp so everything will appear dead. The grill may still function though.
Clock units are expensive so it may be prudent to get an engineer to check it first. 😉Hope that helps,
Steve.
Re: Zanussi ZBQ965X … Clicking noise?
Thanks for the fast response Steve.
It is now switched on and clock has been set manually in accord with the instruction booklet. The oven itself has been turned on to the first setting but neither the grill, fan, nor bulb, are working and there is still this persistant, regular clicking. The clock though, is keeping good time.
Looking from the rear (with the back-panel removed) at the black fan-unit, I see with each ‘click’, the fan blades move rearward a little. So the fan is revolving a whole revolution after time. Would it not do so if, as suggested, the clock relay had failed?
Re: Zanussi ZBQ965X … Clicking noise?
The clicking is the relay making a circuit (fan starts) then immediately breaking it. (fan stops).
The ‘time of day’ display is not connected with the operation of the relay. The ‘manual’ or ‘auto’ part of the clock is responsible for switching the oven on or off using the relay. If the relay is damaged, which seems very likely, then the whole clock unit will require replacement. It is like having an alarm clock with a faulty buzzer. The clock still tells the time but the buzzer that generates the alarm sounds is inoperative. The “buzzer” is, in essence, the same as the relay. It doesn’t ‘generate’ a connection.
Power off before investigating. :plug:Hope that helps,
Steve.
Re: Zanussi ZBQ965X … Clicking noise?
Thanks again for your speedy response!
You weren’t kidding about the costs … eSpares have quoted £150 inclusive for a ‘Programme Set’ but I’ll have to bite the bullet if the oven is to work again.
I may return in a week or so and follow-up this topic line again.
Thank you for your time.
Re: Zanussi ZBQ965X … Clicking noise?
Does your oven have 2 circuit boards below the top cover? One for the display (clock) and another set further back. If so I would not rush into ordering the programme set. This appears to be the control unit but it is the power board which has the relays on for the element switching.
Re: Zanussi ZBQ965X … Clicking noise?
With the rear cover off and peering forward, past the black (presumably, exhaust) fan, there is one circuit-board on the right-hand side but no apparent similar board on the left. There is what I can only describe as a white, rectangular block, on the left-hand side. I did actually wonder myself, whether all communications went through the circuit board and whether this could be the culprit.
Regarding the Programme Set, it’s a three to five day delivery anyway and I won’t be able to order much before next Wednesday for a hopeful delivery next Friday or Saturday, so we do have a bit of time left for further exploration.
If the worst comes to the worst, I may have to take the oven to a specialist rather than me making things worse than they are now but I’ve seen Forums similar to this one before and I think to myself, ‘if other people can fix things with these expert’s help, why not me?’.
Re: Zanussi ZBQ965X … Clicking noise?
The board you say is on the right as you look from the back is the power board. The programme set is the actual display board which runs along the front behind the facia and has the display on it. Attached to the programme set is another small board which is the grill control board. The grill board is no longer available as a seperate unit and comes with the programme set. Depending on your pnc number there can be yet another board which is quite small and attached to the power board. This is a power safety board. 😕
Without seeing the oven in person it would be very difficult to say which of these is giving you your problem. It is probably time to call in professional help.Re: Zanussi ZBQ965X … Clicking noise?
Mmm! Complicated isn’t it? On balance, you may be right! Perhaps I should elicit professional help on this one!!
Thank you very much for the assistance on this matter.
Re: Zanussi ZBQ965X … Clicking noise?
To Aqualectric & Flyman, thank you for your assistance. A local firm in Bridgwater, Somerset, fixed the oven for a modest £108.65 all in.
The problem was that the Lamp-holder switch circuit (Part No: 3570384036) had blown a PCB Powercard (Part No: 3890662046), so whomever had suggested it might not have been the Program-set which was the culprit, was spot-on.
Thanks to all concerned anyway.
