6890 Shutdown 1 Oven Shut Off
Posted: Thu Dec 27, 2018 4:45 am
Oven shuts off while warming up. The flappers in the rear don't quite close all the way. Interestingly, if instead of warming up at 90C I immediately set it to 300C, the flappers shut all the way; I can then set the oven temp at 90C as it's passing through ~85C, and it functions as should. GC runs normally, ramps back down, accepts another run, etc. with no oven warning.
Are these signs of an incipient flapper motor failure? Or is there some maintenance I can do to rectify the situation?
