The original Traeger gasket that allows a temp probe into the grill and provides some amount of air resistance at the hole wore out. This fits the hole and isn't too bad to install. However, it doesn't stay in well enough and the force of pushing the probe through the gasket made it come out. I will try some workarounds such as inserting the probe through before the grill is heated so I can use my hand to hold it in place while I push the probe through. However, the gasket is going to require extra effort to use for its entire life. It needs to be made of stiffer rubber.
