Indesit 3 drawer freezer, drawer front replacement.
Having read the above and examined the replacement fronts I saw that mine had 4 tabs top and bottom, I soon discovered that the bottom 4 tabs were to add rigidity, not to clip into any socket, the bottom rail is just a sliding fit the internal side moulding includes clips which are easily disengaged.
With the drawer upside down and facing me
I inserted a screwdriver in the L & R lateral holes ( just half an inch deep) and gently pulled the old drawer front, towards me. The front simply fell into my lap and the replacement just clicked home when offered up in the same way. What could be easier, and no cause for concern.
