gas fires
fanmaster 5500 turbo
fire will ignite but wont remain lit can i repair or does a gas engineer need to do this
or any tip s please
Hello Ramcab,
Without seeing the appliance in situ it is premature to jump to the conclusion the thermocouple is at fault. There are several possible reasons for a heater to refuse to stay aligh.
Contrary to Top Cats advice, you should never attempt a repair on a gas appliance unless you are competent to do so. Even to gain access to the thermocouple on 5500 almost certainly requires the heater to be removed from its installation, which means breaking gas connections. In domestic and commercial application that must only be carried out by a registered Gas Safe fitter.
For your continued safety and that of your family I suggest to arrange to get a fitter to thelook atthe heater in the caravan.
Now I know this may be a silly question, but you do realise that you need to hold the button down for as much as 30 seconds after the flame lights so that the thermocouple gets hot and lets the flame stay alight?
Like John, I think it highly unlikely the Thermocouple is at fault, however, it's quite possible it's indirectly part of the problem? The point is the thermocouple is only able to do it's job if you have the control knob in the correct position.
Try this, turn the knob towards the marked lighting position, before you get there press down fully and continue to turn, somewhere near the the mark you will feel the knob drop a little further into a slot, here it will lock and prevent further turning, this only place it will light and stay lit after several seconds for the thermocouple to warm and you let go of the knob.
In any other place, the thermocouple is not connected and although the pilot light may well light, the thermocouple cannot do it's job.
Hi Ramcab360.
Don't know a lot about the particular fire but in general gas fires have a "thermo couple" which is a flame failure device to allow the gas to flow. This couple is normally placed with its tip in the flame. These fail and when they do the safety system thinks there is no flame and shuts of the gas supply. Thermo couples are overridden by the pressing of the start valve but as soon as you let it go the gas flow is stopped. They are not involved directly with the gas supply piping and, if you are reasonable at DIY you could replace it yourself. Generally however it does not take long to fit one.
