I did see a case of a p61 where the door gasket was so old the air leak tripped the vacuum switch and the stove would shut down and not startup and run properly.
Here is a P52i Non TC - No touch control.
Approx 9 years old and the door gasket is frayed. The stove still starts and runs fine but not a good idea to have it stop on a cold night.
So how often do you change your door and/or ash pan or ash door gasket?
