Oil Burner Safety Control (TF830.3) - red light was on .......

[Rollerball]

Good point about the pump pressure, I don't know why he didn't measure it either.

I now recall that he did think that the pump was the most likely cause of the issue but then said it would cost about £200 to replace (cost of pump plus his labour) but I wasn't keen on paying £200 for a possible non-repair.

Is the pump tricky to replace? Tempted to buy one and do it myself ......... or is that against safety guidelines as I'm not a certified boiler engineer, etc?

Thanks for that extra info too.

Have never replaced one, but definitely get the pressure checked out first and a flue gas analysis.

The pump pressure is easy to adjust, 5mm allen key needed. The required pump pressure should be on a sticker under the boiler top panel.
Pressure gauges are cheap enough, a flue gas analyser extremely expensive!
Best to check the pump pressure before venturing further.
Now I will stick my neck out.......if you don't adjust the plastic air door, then all should be well from previous work (I hope!)
Changing the pump is dead easy - disconnect the kerosene inlet pipe and the thin one taking high pressure fuel to the nozzle, undo the three allen grub screws and out it comes.
There is a small plastic coupling between the pump and motor, this gives little trouble.
You'll see a fuel tap within the boiler casing.....be warned, they often leak!

Thanks, would something like the following be needed to measure the oil pressure?

It would be a sound move to replace the coil and capacitor first
Cheap and the capacitor can be fitted loose without removing old one .

I have something similar. I use mine together with a Pressure Gauge Manifold, though they seem to have gone up in price since I got mine. Not totally essential but very convenient imo.

The pressure gauge screws into the port marked P, the manifold extension makes the job much easier!
I have the two gauge kit shown on your link which has a flexy length of tube too.
Put some ptfe on the threads first.
It’s always good to have a solenoid coil in as a spare too.....they used to be notorious for failure but the Diamond ones are better. Simple to fit, undo the top nut with pliers and plug it in - no need to replace the cable. They are expensive ( around £35) and new pumps come complete with one.
If you go for a new pump, the pressure must be adjusted, and yours will be around the 100 to 110 psi area I imagine.
