Slow Stove Plates

[darthvader007]

Hi,

I have an electrical stove with solid plates, all plates are with the big red dot in the middle. The stove is about 20 years old. Now I have changed all the plates, but it is still super slow. It does not heat up in 30 minutes, so it is not really usable.

Do you have any ideas why it is so slow? it is running off a single phase 220V 50Hz supply(standard in South Africa).

are the new plates correct rating?

does everything else in the house work as normal?

I am not clued up on these things at all... What is the rating? Rating in terms of what can work with the power supply(220V, 50Hz), because yes, it should, that is the only housing supply we have in South Africa and the plates are from a standard Hardware Store and also the only plates that they have. Everything else is working as normal.

The way I see it, there is nothing really complicated in the stove, PowerSupply->Fuse->Switch->Plate, nothing else, right?

 

[Andy™]

did you use the same power rating as the existing?

could be a faulty thermostat?

Have you anything available to test the voltage of your supply?

Slow red dot plates may be caused by wrong wiring of the control switches. This is probably the cause of your hob's slow performance as evidenced by the fact that the new plates did not solve the problem. Hot plates are usually not thermostatically controlled and the temperature is controlled by separate elements in the plate. The control switch usually switches from lower to higher wattage elements contained in the plate itself. The first setting will connect the lower wattage element, the second will power a higher wattage and the third [and higher] will probably combine the lower wattage elements with the highest element in a variety of combinations [parallel] for finer adjustments.

what about the connections/ links at the point of connection on the back of the cooker? I have had cookers doing wierd stuff then finding a link missing

A bad neutral connection at the connection point ?

(I hope you don't mind if we give you a bit of a grilling)
