Customer:

Hi , is there an overheat cutout on the boiler?

JACUSTOMER-3io817g8- :

there is but i have checked it it is ok and there is a live on the control box

JACUSTOMER-3io817g8- :

you seem to be going off line all the time

Customer:

Someone I answered last night came back on . I am just going to download the manual for your boiler ,please give me a few mins , thanks

JACUSTOMER-3io817g8- :

ok thanks

Customer:

Do you have a multimeter?

JACUSTOMER-3io817g8- :

no

Customer:

if you have power to the burner there are only a few components to test. The high limit statstat, the manual reset overheat stat and the main control stat.

JACUSTOMER-3io817g8- :

am thinking

Customer:

You would need to test these by testing for continuity through them .easy with a multimeter switched to ohms

JACUSTOMER-3io817g8- :

the live and neutral are fine coming to the burner and the connections to the burner

Customer:

yes , but they power is routed through those components that create a safe circuit for the boiler to run

JACUSTOMER-3io817g8- :

the live and netural are fine coing live into the burner

Customer:

If you look at the wiring diagram once the power goes to the burner it then routes through the safety controls

JACUSTOMER-3io817g8- :

is there any componat on the burner itself such as a fuse or reset button that may have switched off

Customer:

Yes , there is a reset button on the burner

Customer:

Should be under a clear plastic cover

JACUSTOMER-3io817g8- :

is there any other one other than thaqt

JACUSTOMER-3io817g8- :

are u talking about the reset button on the control box

Customer:

No ,its possible it could be a fault with the burner control box or the burner transformer

Customer:

Yes

JACUSTOMER-3io817g8- :

we got a new burner box is there any way of testing the burner transformer

Customer:

You could check the amount of voltage that's coming from the transformer to control box

JACUSTOMER-3io817g8- :

am thinking

Customer:

You definitely need to check the stats

JACUSTOMER-3io817g8- :

on the control box should there be live and netural connection going into the control box the same as an oil control box

Customer:

You can get a multimeter for ten pounds

Customer:

I'm pretty sure the power goes from there to the stats, which control if the boiler fires or not

JACUSTOMER-3io817g8- :

i have one though not with me although i am not convinced that's the problem i will check again is it possibel for you to stand by.

Customer:

I have to go out soon , but if we are doing it now that's fine

JACUSTOMER-3io817g8- :

ok thanks very much i wont be long

Customer:

Nonprobs

JACUSTOMER-3io817g8- :

the live is coming through the stats to the burner and am now going to test wi mulitmeter it wioll take me 20 mintues. is there four conncetions going into the transformer

Customer:

It depends what burner model you have . is there a model number on it?

Customer:

Should just be one cable

Customer:

Its the box that sits under the control box usually

Customer:

Hi , do you have power coming from the control box to the fan?

JACUSTOMER-3io817g8- :

model no 40gs5 375526

JACUSTOMER-3io817g8- :

this is oliver house owner mick has gone out tyo test with mulitmeter

Customer:

Ok ,check if you have power from the control box to the fan

JACUSTOMER-3io817g8- :

sorry to hold you there is no power goingto the fan

Customer:

Are you sure the control unit is ok

JACUSTOMER-3io817g8- :

its a new one

Customer:

Ok . I'm sorry but I am stuck myself. If all the stats are ok . the control unit is new , then I'm not sure what else. The only thing I can think is the control unit is a lemon.

Customer:

Hi . I will opt out to see if another expert has any other ideas. All the best

JACUSTOMER-3io817g8- :

on the live connetion going into the control box is showing 230 volts

JACUSTOMER-3io817g8- :

on the live connection going into the control box there is 230 volts

Customer:

That's ok , that's what it should be. I wonder if its worth taking the control unit back

JACUSTOMER-3io817g8- :

sorry i only seen your answer about a lemon now

Customer:

Nonprobs

Customer:

Hi , so sorry have to go out for a couple of hours
