OK, I gave Jimmy a call but he's on a service call on the other side of town, so I'm to call him again after 5PM. How do you know this guy -- personally or professionally?
The fridge is acting peculiarly. I think the freezer part kicked in again since the condensation on the back is now frozen again. Also, I played with the thermostat controller, pulling it back and forth, and after a couple of tugs I hear something kick in. Not very loud, but something none-the-less.
I don't think it's the condenser. I've been googling a bit, and with these frost-free models therre are potential other issues. The frost free apparatus consists of a small heater (to melt the frost), a drain leading to an evaporation tray, a thermostat and some timing circuitry. Periodically, the condenser is shut off and the heater comes on. The heater melts off the frost which goes through the drain hole into the evaporation pan. Then the heater goes off, the condenser goes back on and things go back to normal.
With all those extra parts there are potential issues: timing circuit, thermostat, drain hole. The condenser goes back on right after the heater turns off, so some of the frost may still be melting once the cold comes back on. It's possible for the resulting water to freeze over the drain hole. Over several iterations it could build up quite a bit, eventually covering the evaporator coil. And if the coils are covered in ice, then it cannot do its job.
Or something like that. I feel like Neo.
Whoa! I know refrigerators.
