Hi all,

 

I became a grasshopper to ask questions about my broken Amana bottom freezer. But, now that I'm here, I would like to ask a question about my 2000 Sub-Zero 700-TCI, SN M1661963. It seems to be cooling well (which is good because it has all the crucial food from the old Amana in it). But it's had the service light flashing for months, from time to time. If I turn off the unit, the light stops for a day, a week, a month. But it comes back on. I'm wondering what it might be. It's just the flashing "SERVICE" light, no EE, no flashing ICE. At http://www.appliance...FaultCodes.html I found this:

 

00 SERVICE (Flashing) 38
Several excessive compressor run periods OR
Refrigerator evaporator thermistor fault

 

As for the condenser and evaporator, the condenser coils were somewhat dusty. Now they are clean. And the evaporator, after an hour or so of running, looks like this:

Seems fine to my uneducated eye.

 

I've put it in diagnostic mode multiple times. Here's what I wrote down a few days ago:

 

04 F, 22 R, 03 FE, 16 RE

 

The reason I say "wrote down" is that the R compartment was not that cold. It's full of food, none of it frozen. Either I wrote the number in error, or something is faulty. I suspect the actual temp was 42, not 22. Here's what I wrote over the last half an hour:

 

04 F, 40 R, 04 FE, 33 RE

01 F, 40 R, -08 FE, 34 RE

-07 F, 40 R, -11 FE, 12 RE

 

Clearly the freezer is getting too cold, at times. And my nice new liquid thermometer confirms this. I should also admit I have no idea what the FE and RE readings refer to, let alone mean. I've learned from previous threads that this unit is too old to have all the clever error codes newer units have. So all the data I've got, I've listed here. Perhaps I'm getting excessive compressor runs because the freezer is getting too cold? If so, what might I do about it? Or am I barking up the wrong tree?

 

Thanks for any hints,

 

Franz

Thanks, RegUS_PatOff.

 

That was the freezer evaporator, presumably, as it was at the back of the freezer. I didn't realize there were two evaporators. I guess that's what I paid all the money for, all those years ago. I suppose the fridge evaporator is behind the fresh food compartment. Any reason to take out the contents and look at it?

Thanks for the props on the enormous expenditure. As for the taking apart, I am on it. Or I'll be on it, tomorrow morning. This evening is reserved for family stuff. I am, though, highly curious about the FF evaporator now.

 

Cheers,

 

Franz

Reg, (Is it okay if I call you that?),

 

It's my other fridge that's running constantly (since it almost certainly has a sealed system issue and can't cool down to its setting [though it gets close enough to be useful]). The Sub-Zero does not run constantly. I just went in there to get myself a Sunday evening sort of beverage (if you get my meaning), and the compressor and fan were definitely not on, but the unit's temps were fine.

 

I promise to check out (and upload if it looks odd) my FF evaporator situation, tomorrow.

 

Cheers,

 

Franz

1) yes

2) neither Compressor on the SubZero ?
