Hiya,

Is this the top or main oven stat?

What is the serial number of your machine? Prefix the serial with the letter A or it will be crossed out by the site.

 

Thanks

Hiya,

I know the old switch / stat has 4 connections.

2, 6, f/g and H

 

Can you tell me all the contacts on the new switch and any I've missed on the old one?

 

Thanks

Hiya,

Sorry to keep asking questions, just want to get everything straight.

I'm now confused as I see on the diagram the wire on 6 is from 6 on the timer. Unfortunately I don't have a switch to meter out to see if 2 is switching through to 6.

I'll have to try and email a contact within Zanussi to see if I can get a clear answer on this one.

 

I'll get back to you as soon as I get an answer.

 

Thanks

have got more instructions now as follows. remove connection(double tag) from 5 timer and connect to C on new stat, then cut off small link (F), remove connection 2 and connect to timer (5), remove connection from 6 and connect to A on new stat, remove connection from G/H and connect to B on new stat. also 2 does switch through to 6

Hiya,

Can you meter the new switch please.

B switches to C but where does A switch to?

If you can tell me the combination of switching we'll manage to work this out.

 

The new instructions do make more sense but the wiring diagram I have doesn't show me internal switching on the timer.

 

Thanks

thanks for your reply - A connected to 6 on timer

Hiya,

I got a reply from a contact at Zanussi and he gave this information.

 

Take cables from H on old stat and fit to B on new stat.

Take cable from 6 on old stat and fit to A on new stat.

Cut off link wire from 5 on timer to F on Thermostat. (Shorter wire of the two).

Take cable from 5 on timer and fit to C on new stat.

Take cables from 2 on old stat and fit to 5 on timer.

 

This seems to match up to the 2nd set of instructions you posted.

It also looks ok when compared to the wiring diagram for the appliance.

 

Hope this helps.

 

Thanks
