Thorn Apollo boiler problem, can anyone help?

try lighting the pilot without switching the heatinh/hw on... test like this for an hour... if it still shuts off will give a better of idea of what may be wrong.

Chances are, it only the thermocouple, also the pilot burners are prone to distortion over the years.

could also be a overheat problem, and if you're unliky the gas valve!

You'll need to get a Corgi guy in to check out these posiblities.

Let us know where you are, mayb one of the corgis on here could help.

 

Which model apollo you have a choice of about 20.

gc No will do

Most likely problem is gas valve or pilot flame

 

its fine...

70% sure it thes theremocouple
25% the pilot buner needs replacing/injector cleaning
5% i could be wrong!!!!

 

Boiler model and gc number is on the plate inside the door

Thermocouple has an overheat connection which could also be a problem.

if the pilot stays alight then the thermocouple is ok.

need the number

 

if its only the thermocouple/pilot then £50 should be about right...

I'm pretty sure its not actually overheating, but as DoItAll says it could be a faulty overheat stat as well...

probally best to change all 3... Should be less £100 all in, hopefully closer to the £50 tho.

shame you're not a bit closer!

 

We got guys live in trowbridge, frome, melksham, westbury and god know where else spike.

lets find out whats wrong first, may be something simple like re-setting the gas valve.

thats the grey knob, turn it in the direction of the arrow and wait 3 mins or till you hear it click, then light the pilot.

 

No according to the gas valve number you have the 40B GC number 41-789-79

It seems to be the only model with that valve

 

Sorry yes you can light it with the electric off.

on the thermocouple about half way along theres two wires coming off, temporarily bridge them with a piece of wire and see if the pilot stays on then.

post an email address.

 

8409 boiler manufactored sept 1984

the data plate is on outside of silver meatl casing, just above the two numbers you quoted.

to access, you need to undo one screw which hold white case on at center bottom of white case, it'll then lift off.

 

mail on its way

I'm a single mum and my Apollo boiler has been doing just as on the first page describes. My heating guy came out did a full service and told me the boiler is old and it could be a number of things but he is not interested in TRYING to find out what it is. He's changed the thermocouple but already it was not that. He said he could spend a few hundred quid of my money replacing what you say here and it not be any of them, needs a new boiler and I don't have £2,000 right now. My son is 6 needs bath etc and so hopefully heating man is coming out again this Saturday to see if it's any of these things you all say it could be here. I get the pilot to light then 5 mintues it clicks off and I have to wait turn it all off and try to light it again. He gave it all a good clean etc with the service and had it on high and continuous and it worked that night then following morning it was off again.

Any further suggestions would be appreciated.

If they are Thorn Apollo's then that's the oldest model of Apollo & could be 20+ years old.
The Apollo is a simple enough wee boiler, with a limited number of controls. With the high temperature cut-out being one of the most common faults, as said. This intercepts the pilot in a couple of ways, but given that's it's a Thorn I'd say it be via two connections as stated above. You both need a Corgy RGI, who knows the appliance.

Sorry, but you also both need new boilers.

 

Kimbers64,if you are a single mum and on certain benefits you may qualify for a warmfront grant for a new boiler not 100% sure but worth a try
