Give me a museum and I'll fill it. (Picasso) Give me a forum ...
I had to clear the drain on our Whirlpool refrigerator again yesterday. It froze over for the second time in a month. I made absolutely sure it was clear this time.
So far I've replaced the defrost timer, defrost thermostat, and temperature controller. I also cleaned all the dust bunnies from the coils under the fridge. The defrost system IS working, and it maintains the proper temperature in the fridge and freezer compartments, but the fridge still seems to run all the time.
The condenser fan runs, but it seems kind of slow to me, so I have a new fan on order. Hopefully that will fix the continual run situation.
Oh, and I somehow broke the ice maker and had to get a new one. Oops.
We thought about just getting a new fridge but they're $1000 and back ordered everywhere. The new fridges are deeper than our current one, which would stick out further into our walkway. I would have to replace the water supply valve for the ice maker with a new inset valve so the fridge could be pushed back further. That's plumbing and sheetrock work I would prefer to avoid right now. So, I'll keep this fridge going as long as I can.
Of course you already cleaned the coils on the fridge.
Maybe try squirting some warm, diluted bleach solution down the drain tube, perhaps there is growth in there that only takes a little freezing to blow it.
