So, some mice dug around in the insulation around my MGR6875ADS lower oven.
Now, whenever there is a flame ignition, after a few minutes there is a *whuff* and flame erupts from behind the case, from a slit through which I can see the ceramic wool insulation. There are no evidence of leaks upstream of the safety valve. Could it be a leak between the safety and the nozzle? Could this be a leveling issue?
There was definitely some insulation that had been dragged into the air intake area beneath the burner assembly, but I was surprised to find that clearing it out did not solve the problem.
I have not tested more than a few minutes, but the issue appears to *NOT* occur when the burner plate or baffle or whatever is removed. If I let the gas burner free-burn without the shroud on it, it burns correctly. If I place the plate back over the burner, poof.
What sort of issues could cause this? I'm used to stove issues being fairly obvious, but I just cannot figure this one out. Thanks in advance for any help.
