Its the turn of my warm air central heating to need mending
It was playing up bit time, investigation revealed this

Am I ok to just replace these?
Ive bought a new PCB as it seemed the best option to quickly get the system running again, and to also identify the bad components, as this isnt a common unit theres not a lot of info out there on it. Ideally I'd like to repair this in case of 'next time'. clearly no urgency to this now though.
Can put other photos on if needed. Of old or new
