The lower seal develops cracks and eventually leaks hot air into the airbox
causing the safety lockout to trip

Can anyone suggest why this happens, the top seal and side seals eventually
harden but stay sealing after several years. The bottom seal seems to
start to crack as shown after a couple of months.
I am awaiting a reply from Potterton.
