Re: Neff oven timer problem

Neff-Cooker-Oven- U/B1322n1gb-01-B1322-Fd3605-Display-timer-clock-unit. This is the 2 button unit, which has two white relays. These are schrack 0410 63 054 002 which seem to be out of date – replacement parts are RFH54006WG RF900016WG tyco Power Relay available on, for example, Ebay £12 for two.

Symptom: the delay start function on the timer isn’t working – you set it, but the cooker doesn’t stay off to the allotted start time
Cause: Main element blows causing overcurrent, welding the contacts together in the relays, so it always stays on

To replace them, by yourself a soldering iron and simple desoldering pump (to suck the old solder off).
1. Isolate the cooker, remove the top tin cover (about 4 screws)
2. Remove the power clip (white connector) and 4 cables with spades attached to the 2 relays (keep a note/picture of which goes where)
3. Remove the clock (2 press tabs on the underside) and remove the circuit board (some clips around the edges – 4 thin, 2 wide)
4. Remove the solder from the relay coil pins (2 per relay) and from the underside of the blades (2pinsx2) by heating the solder and using the desoldering pump.
5. Lever off the old relays (you may wish to snip the pins to make it easier) and throw away.
6. Put in the new relays, bend the pins as to hold the relays in (as per the old relay), and apply solder
7. Refit (steps 1-3, in reverse) and all is good, saving £100+
