oven thermocouple?

[southcoastboile]

Did a safety check on an oven yesterday and found that when you turn the oven on it immediately lets through a lot of gas or a small amount according to what number the dial is on

I.E on 1 the flame will light fairly small but on 9 it will come up to max flame without starting off small.

The size of the flame regulates according to temprature setting so I think the oven thermostat is ok.

I assumed it was a fault with the FFD so I ID'd it and said they need a new one.

Parts stockists came back to me saying it was not an FFD its an oven thermocouple. If thats the case it is probably working correctly. Can anyone confirm for sure that with a thermocouple it should not start at min flame?

Thanks alot

A thermocouple FFD is either on or off at full rate (assuming the oven is cool) and you would need to press and hold a button or knob after lighting the burner to get it to hold.
The thermostat only varies the flame height when the set temperature has been or is close to being reached.
Have you the model or GC no of the cooker?

its a beko oven, I can get the model number tomorrow, there was no GC on it. So if its a thermocouple type do you think its working correctly?

If it's a t/c, as mountainman says, you have to hold in the control knob to establish the flame. Just turning the knob should'n allow gas through until you press it in Small flame rising to large points more to a mercury vapour type FFD.

is it the type with the flame at the back or one with the burner under the oven (the ones where you just have a few peep holes in the oven floor to see the flame)

A thermocouple with a thermo electric valve is an FFD

A Mercury vapour is more likely to be an FSD

Does the oven have a FSD or just an FFD?

Did you check the operation of the thermostat/bypass?
Did you check the operation of the FFD?

Is a FFD not an FSD and vice versa?

[AWheating]

sounds like the thing was working correctly, i would first check the instructions or maybe phone the manufacture for advise?

FFD is the older term for FSD.

The burner was at the rear, I think it's working ok if its just a thermocouple but the ignition does not work and were the burner lets gas through at full rate it seems dangerous having to lean in the oven slightly and light it manualy with the possible gas build up. I have had no luck in contacting the manufacturers.

Silly ain't it?

Lessen the risk and use long kitchen matches and don't press the thermocouple button/knob until the match is alight and positioned at the burner.
