Hello, I know you guys get this question all the time but I've been having a heck of a time with my insert this year. I've had it since 2013. I deep cleaned it this summer and everything was great the first week or two after we turned it on. Now I can't get it to burn for more than a day without being completely overrun with half burned clinkers and huge, lazy flames. At first I thought it was what it always is and cleaned it out again, worked a bit better for a night and then back to the same old issue. I tried the dollar bill test and the door is solid while the ash tray wasn't. I bought a new gasket and while it offers a bit more resistance, I can still get the bill out fairly easy. The ash tray itself is all kind of warped (the front looks fine), could this be the issue? I'm not sure what else I can clean, I've taken off the inside baffles, vacuumed the vent pipe, the intake, the motors, the tubes, etc. If there's something that's often missed please let me know and I'll try that. The place I bought it from is out of business so I'm hoping to knock this out myself but I'm getting close to finding a technician. Thank you for any help in advance.
