Has anyone got a wiring diagram for the timer of a zanussi fridge freezer ZX57/3S1. Its the Sankyo one. I went to fit a universal one to it, pulled off the wires and then confused myself and spent the next half hour trying to work it out. I think ive cracked it but want to double check
Thanks

Re: Zan defrost timer wiring
From wiring diagram on TDS shows the following for the sankyo timer
1 live
2 to defrost heaters
3 neutral
4 to compressor and fan
There are several ZX57/3SI but with different pnc numbers, the wiring looks the same.Malc
Re: Zan defrost timer wiring
Had the same problem last week and was given this gem by Paragon timers. The concept is that you have one neutral tag and one live tag that feed the timer motor and the live is also switched between either the compressor or the defrost heater. If You manually turn the timer (power off) you will get a long period with no contact action and a short period with the same. (listen for the click of the contacts) the long period is normal compressor operation and the short period is defrost. So, once established which is which you can see where the switching goes.
The layout on the paragon is –4 3 2 1
where 1 = neutral
3 = common switched live
2 = compressor
4 = defrost heaterIt works with all of these types of timer – once you have established which is the neutral you can then work out the others from their switching.
Good luck
