removing burned in screw from stove

brodev

I have a wood burning stove in a house I have just moved into. It requires a replacement glass as one has cracked. The old glass is held in by 3 brackets which are held on by 3 screws. The screws have phillips heads but refuse to budge. Anybody any idea on how to move them or will I need to drill and tap.

A little bit wd40 on them? make sure the phillips is the best fit it can be, perhaps even try a flat head if it gets a better grip of the screwhead.
Have you tried to tighten them slightly? (just to break whatevers stopping them loosening without damaging the side of the screw needed to remove).
Failing that, a bit of heat perhaps?

System

failing all else screwfix do a screw extraction set for approx £2-50.

try removing them when the stove has been on

The stove would be cast and the screws could be steel/brass, with the differnece in contraction caused by heat you may be able to free them
