Whirlpool ED27RQXXW00 Side/Side Fridge
Posted 23 July 2005 - 03:42 AM
The controls for the unit are set at max cold for the freezer ("C" on the control) and medium for the fridge ("3" out of 5 on the control). The ice maker works normally.
I removed the cover on the Evaporator and found it to have a bit of frost on it but not the block of ice that I expected. The Evaporator Fan was running. I located the Defrost Timer and turned the timer clockwise until the machine stopped running. The Defrost heater got hot and melted the small amount of frost. Moved the Defrost Timer forward and the machine began running again. Set a timer for 8 hours later and the machine was still running - at about 10 hours the machine shut down for a while - defrosted the evaporator coils again - and then started up again.
Peering at the Condenser Coils under the machine, I could see some dust on the coils. It didn't look bad but it doesn't cost anything to clean the machine so I removed a significant amount of dust (much more than I expected). After the cleaning I hoped there might be an improvement to temperature of the compartments but that hasn't happened. While I was cleaning the coils I could see that the Condenser Fan was spinning nicely and air was moving under the machine.
It is difficult to say how long this situation has existed. We only noticed the problem and started checking things when we noticed that our ice cream was soft. When we first got the machine 14 years ago we ate more ice cream than we do now and didn't notice this problem. The machine is fairly quiet so, until we started paying attention, we didn't really notice that the machine was running all the time.
This unworthy one awaits wisdom.

After it's been on normal settings for 24 hours, check the temps in both cavities and get back with us.
Do you have the rear panel installed? It may look like a piece of worthless cardboard, but it needs to be there for proper operation.

I have to say that, at the time I did the above tests, I was unaware of when the defrost timer would activate the defrost cycle. (Could that skew the temperatures if my timing was bad?) Since I'm not sure when the Defrost Cycle was running, I suppose Murphy's Law might in come into play and might change the results of the above test. I think that would be a remote possibility but it has to be considered.
When you refer to the "rear panel" are you asking about the cover over the Evaporator Coil? Yes, I have re-installed panel over the Evaporator Coil. I seemed to me that the Evaporator Coil Fan needs this cover to get the air to flow over the coils properly.
The reason I waited until now to start "operating" on the machine was to allow us to eat our way to a lower level of food in the machine. This week we got to a point where the food could be moved to the beat-up 25-year old "Beer Fridge" out in the garage. (It's freezer temp is a bit below zero by the way.)
I'll try your suggestion but, unless Muphy is a factor, I don't think the results will be favorable.

If things are not right after 24 hours, I think you may be done investigating. From all the tests and work you have done, I believe you have a sealed system problem. Either you have lost some refrigerant, or the compressor it worn out and not pumping to normal pressures. Either way, looks like a trip to an appliance retailer is in your future. I wouldn't recommend sealed system repairs on a machine this old, because of the high cost involved.
But you did a nice job hunting for the problem.

When I wrote my original post I suspected that this was a "sealed system" problem but thought it was worth running the situation up a flagpole to see if there was something else possible.
I'll pull the fridge out and have a look for the cardboard cover.
Thanks to all for taking the time to discuss this with me.
