How easy is it to replace a ENO cooker oven thermostat?

I have the classic symptoms - oven burner fails to sustain when the On tap is released so all fingers point at a duff thermostat.

My question has anybody ever replaced this thermostat and how easy is it to do?

Looking at the picture of the replacement unit it looks fairly straight forward but I don't want to blow the boat up!

FFD, flame failure device, not thermostat, just replaced my 3 and written it up for PBO. The biggest issue is getting the top off to get at the control valves, the burners are screwed to it and the SS screws in to the aluminium burners seize. I drilled them out. Once that is off then you can use an 8 mm spanner to unscrew the brass nut holding the copper thing with the wire inside. Using a multimeter you should see 20-30 millivolts at the contact when a gas lighter flame is put on the nipple that sits in the flame. Mine read 8 millivolts so werent energising the holding coil enough.

PS you will have to lift the stove off the gimbles, the sides have to be removed to change the oven FFD, the gas pipe has to be undone, 14mm spanners, holding one under the top so remove the top first. The connection is a bog std olive and is the only gas connection that you have to undo, the FFDs are fail safe and are not gas live.

Thanks for getting back.

Just to be clear I am thinking of replacing ENO Cooker Spare Oven Thermocouple. (https://www.socal.co.uk/marine-leis...ooker-spare-oven-thermocouple-all-models.html)

As yet, I haven't dismantled the stove so where does the thermocouple connect into the cooker?

When you speak of 'getting the top off' I assume you are refering to the top of the stove?

I had a problem with the oven failing to sustain.

I moved the end of the flame sensor closer to the top of the inner cone of the flame and centralised it, bit of hit and miss here.

I took the oven door off to ease access.

It was a tedious job but saved a deep strip to replace.

Good luck

You know how thing happen in 3’s...

My wife finally gave up on patience last weekend with the same problem so I’ve been checking out this week on doing it.

It’s nice to have a mutual support group!

Before you go tearing into it check that the tip of the thermocouple , aka flame failure device. is in the flame and has not been dislodged
 
What about an Eno oven that no longer gets as hot? Being the basic one I don't think it has a thermostat - just bigger or smaller flames depending on the knob position. However, the flames are never as big as they used to be. Gas bottles make no difference and the rings seems to be as good as ever, and having them on or off doesn't change the oven flame height. So I assume something is slowing the gas flow just to the oven.
Any suggestions?

I took the curved flame tube off, one screw and the ffd hold it in place, the jet gets "blocked" with carbon and needs a poke with a wire to clean it, I also found that the tube was half full of loose carbon. Cleaning it all out nearly doubled the flame size, however yellow tops appeared, a sign of incomplete combustion. There is an "air throttle" hole with an adjustable band over it that allows more or less air in to the burner. I adjusted it until I got a blue flame throughout. The oven is now "hotter and quicker"
The top I refer to is the top of the stove under the wire stand. This has to come off before the sides and back come off. The ffd for the oven runs across and down the side under the figlass insulation. All very simple but the sequence has to be followed dismantling it. It is held together by self tappers in to captive sheet nuts. The captive nuts slide off without you noticeing be warned, guess how I know?

Thanks to Stu and all you others for the advice. :angel:

As advised I have rechecked the thermocouple and all the fingers of suspicion point firmly in that direction. :(

So just about to order the bit and when it arrive here in rainy Lagos, attack the stove.

End of the salad season is insight - hurray. :encouragement:

As they say, pictures say a thousands words

Thats it, just like mine, the voltage check is between the centre and the outside.

Bluddy hell, they know how to lean on the pencil, as you can see mine were cheap as chips from the Spanish Chandlery in La Linea

Re: How easy is it to replace a ENO cooker oven thermocouple?

Just one more question.

No wires apparent so how do you measure thermocouple output voltage? Between outer copper casing & centre of connector?

Have you tried holding the button in a bit longer? Enough to get the fed hot?
 
Salad Season OVER!

Stove once again fully serviceable.

Many thanks for all the help and advice and a special thank you to Skipper_Stu. Looking forward to reading your article in PBO. Any idea which issue it will be in?

Should also record my thanks to Peter Spreadborough and the sales staff at SoCal (Southampton Calor Centre) for excellent technical advice and very efficient delivery service. Ordered late on Monday evening and here in Lagos by Friday morning.

That's the fridge and oven fixed so what's next?

Sometimes don't you just love boats!

I did the story, sent it off. The Ed decides when it goes in.
