Eventually it will break.
This is the rule for household appliances. I would just prefer that it not be a two year old microwave that I had installed into the kitchen cabinetry. Yes, I can probably fix it… after I dismount it and lower it out of place. A task much easier typed than done. No matter, I am on-call this weekend. I will be around the house all day anyway, may as well get something productive done.
An over-the-stove microwave costs a few hundred dollars, too much to just run out and buy a new one. Not enough to justify a repair call. I do not even want to think of what it would cost to get a repairman out to the house. Driving from Kona? Hawaiian rates? I can think of few easier ways to get robbed.
