I have a leisure rangemaster 110 double gas oven the left oven stays low i have tried cleaning jets but this has no effect can you suggest a cause

Bolcked injectors and blocked burner jets . I would also check and see if you have a valve on the that might be not be fully on . All points to lack of gas pressure I would also check the reg on your tank or bottle .

hello Terry,

it is not to difficult.
I tried to download a picture here, but that does not work.
On this link, you can see how they look like:

Here you have the complete unit. This unit is connected at the bottem of the oven with 2 screws. You need also to disconnect the small gaspipe. Then you can remove the whole item.
When that is done you easyly can remove and replace the ffd.
I wish you succes.

Kind regards, Di

Hi Stella,

i am sorry for you, but you can forget repairing the timer.
You can replace it of course.
You do not need the timer to operate the oven.
For that you need to bypass the timer. The clock will stay working normally.
Although the 55 is smaller then the 110, the working of the clock should be the same.
Net link will give you more information and I hope you will fin the solution there.
Kind regards and a good weekend, Dik

Leisure Rangemaster 110 Electric Range Cooker How to bypass

Your left hand oven is a conventional oven it has two heating elements one at the top and one at the bottom, if one of these is not working then the high temperature cannot be reached.

common problem, there is a device in the oven called a solenoid/ff device these are safety devices and fail after a few years. replacements can be obtained from main stockist Gas On spares on 0121-585-7799

Faulty FFD's ( flame failure devices) once the flame is established it allows the full flow of gas to the burner... must be a gas-safe engineer to replace part..

sounds like your jets are blocked try poking a bit of wire in them carfully.

Its the flame failure device faulty (FFD)

Hi
Just to say we sorted the problem. Simply the bulb was out in the one oven. We replaced this and problem solved.

Reading the user manual, it states that the flame initially comes on low, until it is "sensed" by the flame sensing device. This to me sounds suspiciously like the flame isn't being sensed and so never gets increased to the normal level.
I've not had time for a proper look at it.... but from a quick glance this morning this looked like a "flame rectifier" probe next to my burner (as we commonly use in boilers to sense if the gas burner is lit). This is just a metal probe. They send a high-ish AC voltage signal (Sine wave) from it, through the flame, to the earthed metal case. The flame acts like a diode (yes it really does work !) and simple electronics detects the change in the applied signal (rectified) due to the flame. I know from personal experience they (the probes) get coated with crud (carbon, etc) and need a good clean. I suggest you try cleaning both it and the metal area opposite it. If necessary the probes metal tip could be GENTLY rubbed with very fine Emmery cloth, etc, if badly coated.
Other than that, if it is sensing the flame, then it must be the gas control device (solenoid valve ?) that is jammed, blocked or just defective.
Simples......
