Freezer too warm - thermostat or leak?

1

Frigidaire FRS26LR5CW0 side by side fridge/freezer. Freezer side is cool, but not cold - things were slowly thawing and new stuff not freezing so I had to remove everything. Fridge side is just cool enough to keep the food in it.

What I've done/checked:

Cleaned exterior front/back coils/compressor/kick plate. Verified the exterior compressor fan works--Compressor comes on (i can hear it) I removed interior back panel of freezer - the fan above the coils works, as well as the fan that blows from freezer into fridge (located on left rear Fridge wall). When i first opened the back up, the freezer coils were frozen, but only the top 1-2 rows. I believe the inlet line is the small diamater line - that line had a big block of ice formed on it, probably an inch thick. I've defrosted and re-started and the inlet line (the small diameter) almost immediately frosts up, and within a couple of hours the first row is frosted up. I let it run for 4 days and got another block of ice...

Sounds to me like your fridge has built in coils, which is the cause of the heat on the outside sides (condensing), and that your refrigerant is low, likely due to a leak.

To start with, you have to understand how it works to get the why. The refrigerant gas is compressed, passes through the outside coils (condenser) releasing heat and turning into a liquid. The compressed liquid goes through an expansion valve, reducing the pressure and extracting heat from inside (evaporator), turning back into a gas, where the process repeats. Your refrigerator is working (heat being released outside, heat being extracted/cooling slightly inside), but because of the low refrigerant, you have lower pressure which means a lower boiling point.

My opinion is that the compressor does more work trying to compress the gas, it is generating more heat outside, but less heat is extracted inside because the liquid changes back to a gas more quickly. I would recommend a worthwhile service...

Complaint.

Freezer Too Warm.

Evaporate or Blocked With Ice.

Clause-Remedy

1. Inoperative fan motor - check wiring and fan motor.

2. Improperly positioned fan blade - position blade at

end of shaft.

3. Evaporator iced up - check defrost system.

4. Defrost heater in operative - check wiring and

defrost heater.

5. In operative defrost thermostat - checked wiring and

defrost thermostat.

7. Wire loose at defrost timer - repair wire.

8. Excessive service load - advised customer.

9. Freezer lid left open - advise customer.

10. Controlled thermostat out of calibration - replace

control.

11. Lid gasket not sealing - adjust or replaced

necessary parts.

12. Control thermostats sensing element improperly

positioned - reposition sensing element.

13. Shortage of refrigerant - check for leaks.

14. Restricted filter drier or capillary tube -...

Stan HarrisonFeatured FlashbacksWhen food spills mar the glass inside your oven door, there is a way to remove them. Here's how to take apart the oven door so you can clean the glass -- inside and out! Broken light switch? It could be a fairly simple matter to replace it -- if no other switches or outlets share the same electrical box. Warning: Before doing or touching anything, turn off the power at the circuit breaker box or fuse box!Watch Stan's helpful how-to videos.

Refrigerator Temperature Control Dial - What Do The Numbers Relate ...
USUALLY the higher the number on the temp control dial, the colder the temperature your refrigerator will get. If your drinks and food are not as cold as you like, set the temperature dial up one number higher. If it is at 3 and you want your food colder, set it to 4 and test 12-24 hours later to see if your food is ...

Best Refrigerator Temperature to Keep Food Fresh - Consumer Reports
Knowing that, the reasonable step would be to set your refrigerator to those temperatures. But the temperature controls on many refrigerators only allow you to choose from a series of numbers—say, from 1 to 5, with 1 being the coldest and 5 the warmest. Even when refrigerators have digital controls that ...

I was always clueless about how a freezer defrosted itself as well. I remember the first apartment I lived in had one of the older freezers that didn't defrost. It was a nightmare to get rid of the ice. You could run the defrost setting, but then you ran the risk of ruining your food. Scraping it never seemed to help either, and there always warnings that using something like a screwdriver or ice pick could puncture the wall and ruin the freezer. I'm thankful for whoever invented the self-defrost.

Anyway, I notice that sometimes a small amount of frost starts to build up in my freezer. I wonder if maybe my thermostat is out of line like the

article mentioned. We were moving the fridge recently while were were retiling the floor and painting the walls. Does anyone know of an easy way to test the defrost thermostat and fix it if it is not at the right settings? Maybe it is something that I...

Most homeowners consider the refrigerator as one of the hardest working appliances in their home. Today, it is difficult to imagine a life without a refrigeration appliance. However, if the fridge or the freezer is too warm, it becomes difficult to store the fruits and vegetables in the refrigerator.

There are several parts that can cause the freezer and the fridge to become too warm. To rectify the problem, you must inspect each part carefully and replace the problem part. Here are a few tips to identify and repair these parts.

Evaporator Fan Motor

You can find the evaporator fan motor in the freezer compartment. The evaporator fan is used to circulate the cold air throughout the refrigerator. If the fan is damaged or defective, the temperature in the freezer section will increase slowly. This will force the compressor to run longer and more frequently. This can affect the cooling efficiency of the refrigerator.

If the evaporator fan is not...

Quick answer, buy a small ice maker unit designed for a wet bar or small outdoor kitchen. The units I worked on was basically what you are trying to build. By the time you build your own unit you aren't too far from the price of a unit already made.

What follows is the long story of why you should chalk it up as a good idea but too much crap to deal with.

I've been out of the small appliance repair biz for about 10 years so the information may be dated. I would double check location and routing of the evaporator lines (cooling coils), in most of the small freezer chest units I worked on the evap lines ran on 4 sides embedded into the walls.

There was no real way to really tell just where the line really was inside the wall. Sometimes, there is a sort of layout of the refrigerate lines posted in the handbook or on a sticker pasted the the backside. Many times, there was not. One wrong hole drilled into the cabinate at the wrong place and you are screwed!

Due the...

The ice on the coils was negligible.

Well, not iced up. Sounds like it can't ice up anyway.

I switched it back on and the coils at the top of the freezing element started to get cold quite quickly and soon my fingers were sticking slightly when touching.

OK, some capacity, but with cover removed to 'touch' there isn't designed air flow that would strip that ice anyway. KWIM?

The bottom of the freezing coils were not overly cold, but none the less cold.

Happens because there is gas flow in there and some carry-over of chill. Thats needed all the way back to compressor dome, so the motor windings get some cooling too. You would want to see ice over the whole coil... then again, because of the heat in cabinet it could take some time to form.

Only thing of note was that where the freezer coils joined the very thin copper line to the dryer (or from the dryer???) there black insulating tape round it which looked like it...
