How do i change signal lamp on rangemaster cooker

I believe you will find your answer on this site. In reading how someone else did it, some of the screws appear to be quite well hidden.

If its a Rangemaster induction cooker, I had the same problem and its caused by a Loose or faulty PT sensor under the glass, you need a qualified engineer to rectify it.

Hello,
The regulations state that the proximity of the hob to the cooker would dictate the use of a copper pipe to supply the hob.

Hope this helps.

Remove hotplate and oven control knobs. Under the 2nd and 5th knobs is an extra screw which holds on the front cover. Unscrew these and free the cover then access is gained to the screws (2 on each edge) which removes the plate to which the regulators are fixed.Remove the faulty regulator by unscrewing it from the plate,(2 screws) It is an easy job then to install the new part taking care to put the correct wires on the correct terminals. Reassemble, job done!

Thios induction hob (Electrolux) has 4 wires - Y/G, brown. blue and black.
The Y/G is obviously the Earth conductor, and I would assume normality says that
Brown is the live conductor and Blue the neutral conductor.
The quandry is whether or not to disconnect the black wire completely, as this appears to have no function in a domestic wiring circuit.

Nope

problem with hob is probably water ingress in area of ignition unit - will probably cure itself oven is a completely separate unit from hob. problem with it is that you have to re-set the clock - you have it on automatic. after power outage, oven clock always has to be reset
