Fired up the stove for first time yesterday (model 10-cpm 49 shcpm 49 trcpm new englander) and it wouldnt stay lit. All gaskets are new on it, fully cleaned top to bottom before using. It feels like there is some air escaping near the handle on the door, even with new door gasket. i dont see any other issues that might cause the low flame and eventual shut off, any thoughts? thanks
