1. Decide to finally heed the "clean me" light on the range hood and remove washable filter screen for cleaning.
2. Promptly drop one filter behind the stove.
3. Attempt to fish out with extendable magnetic probe-- no result; can't even tell where the filter has ended up.
4. Attempt to probe behind stove with wooden dowel. Accidentally drop dowel as well.
5. Realize that the storage drawer beneath the oven can probably be pulled out for access. Successfully(!) pull out drawer without major trauma.
6. Observe filter and dowel companionably resting against wall behind stove. Also observe that the drawer gap is not large enough to tilt the filter out from the bottom for retrieval, and that the filter appears to have no ferromagnetic components.
...so at this point, I guess I'll wait for the rest of the day until the wombat-consort gets home from work, and maybe then I can try to use kitchen tongs to lift up the bottom of the wooden dowel until he can grab it from the top of the stove again. (The stove is probably too heavy for him to move by himself, and I'm not terribly useful in appliance-moving assistance right now.) I guess if I were really clever, I could try fastening the bottom of the dowel to the filter-- maybe by reaching a piece of packing tape onto them with the tongs?-- so it would pull the filter up at the same time. However, I have probably considerably overextended my Cleverness Allowance already :b
