In Topic: subzero 532- frost on back wall normal ?

yes, authorized subzero tech. the only shop in los angeles.
He did my warranty work a decade ago.

thermometer says my fridge is cooling to 35F now. Before, it wouldn't dip below 43F.
maybe blowing out the condenser coils helped..

but there is a little powdery frost starting to form on the back wall.
will have to observe a few more days.

tech came today, and measured freon level. it was at ~8.5. He filled it back up to 10.
He topped off the freon 8 years ago.

if it's a closed system, isn't freon supposed to stay at the same level forever ?


He didn't check for leak, though he did entertain the idea.
he thinks that cleaning out whatever remaining dust in condenser coil might solve the frost/icing problem. Basically a wait & see approach.

He said, in the worst case scenario, if it were an evaporator leak, he would have to change the evaporator AND the compressor.
Anyone know why the 2 must be replaced together ?


My evaporator seems to ice up whenever it's hot outside, 100*F weather, which we had the past week. Kitchen is probably 86*F.
Tech thinks the compressor might be overheating, and not cooling efficiently as a result.
But there is nothing wrong with the compressors themselves; they are nice and quiet.

If there's a leak, in what scenario does the evaporator need to be replaced ?

and if the evaporator needs to be replaced, I remember reading there was one type of evaporator that I need to avoid- one with inferior materials ?

Do I have a small leak?

The backwall frosted up a little more today, and the fridge temp rose to 56F, so I took the back panel off.

I heard the compressor shut off by itself today, so it's not running forever.
While I had the back panel off, the compressor turned back on.

Below is what the frost pattern looks like when the front side of the wall is frosted...
I already replaced the thermal control you see there.

What do you think needs to be fixed?
I'm gonna have a tech look at it, but just to get some 2nd opinions from you guys, what do I need to ask or look out for... in case he misses something ?
