Took the inner front panel off and 'exposed' the burners. it fired ok and heated water & ch. Put the cover back on and it shuts down again. Apparently, the air pressure switch needs replacing. Any ideas what to get and is it easy to fit?

not guaranteed switch but yes something based around the pressure switch, tubing, venturi fan etc. You shouldnt really be in there anyway, can you prove all seals are still in good order? is there a potential hazard that youve missed which a rgi would have spotted?
