Good news! I've just added an Aga range cooker door liner replacement kit, at the request of a customer!, to the store. You can find the kits at the page - door liners/insides, DIY replacement kit, for use with Aga range cookers.
Kits for all supported Aga range cooker models are available. If you aren't sure which model you have then check out our handy guide to which Aga range cooker you have.
So if your cooker's door liners are hanging off or look like the picture below then perhaps it's time you had some new ones!
