Shower mixer - broken or adjustable?

[Johnking]

Anyone know if this model of shower mixer can be adjusted? It never gets quite hot enough, but if I give the knob a bit of a nudge it does sometimes give me a busrts of hot, so I know the boiler is capable. It looks like there are adjustment screws on either side of the (lower) thermostat knob, but they seem frozen up and I don't want to force them in case I knacker it.

I expect the thermostat cartridge is knackered.

The word cartridge suggests it might be replaceable, is it?

Any idea how to find out what model, where to get a part, and how to fit it?

Sorry, total plumbing virgin.

Try removing the one that's in there. It might have a number on it or a name. If it has try googling it.
Apart from that I dunno!!

Took it apart, realised the stop had been set too low, there was nothing wrong with it! Thanks for your advice.
