Well I thought I had the answer.....If all else fails, read the instructions...
The inner door panel can not be removed. See P. 15, Section 5, Para 1. ["...i.e. the door panel cannot be removed."] of the recently posted manual for the RM24 Dometic fridge
However, the science project that was my fridge
door has been removed. I opted for a total immersion, some good, friendly cleaner, elbow grease, a scrub brush, q tips and a shower rinse. Now I will wait it out for a thorough drying period.
I do not know what may be growing or evolving in the sewers under our fair town as a result of my actions but I hope it does not come back to haunt me.
Thanks again. D.
