LG fridge… I’m poking around w/ my fridge, the basic symptom is “doesn’t cool enough”. I hired a certified fridge repair guy, but he looked at it for 10 minutes and pronounced it “dead and worthless. It has a clog. Don’t bother replacing it, it’s not worth it”. I contacted LG and they said even though it has a 10 year warranty on the sealed system, there is only ONE technician they will send out for coverage of the seal system’s parts, and that one guy charges a flat rate of $950. Yeah, right, I don’t think so.
Symptoms:
- Frost all over the freezer evaporator coil.
- Frost on first 8" only in the fridge’s evaporator coil.
- while-running low-side PSIG reading: 5
- while-not-running stable low-side PSIG reading: 30
- PCB just replaced
- Temperature sensors verified to be in-range
- M-FUSES verified working
- Compressor sounds good and “happy”, very quiet (linear compressor)
- can hear (and feel) gurgling freon through the evaporator coils, both of them.
- Sticker on fridge states Low Pressure: 140 PSI Ga, High Pressure: 400 PSI Ga.
- Fridge is set to 36F, but temperature inside reads 50-55F most of the time.
Technician’s diagnosis: You have a clog. It’s affecting refrigeration, you should throw out your $3000 fridge. Don’t try to repair it.
My questions:
-
140 PSI Ga - what’s that mean? not-running pressure on the low-side, or while-running pressure? If mine’s reading “5” and it’s supposed to be “140” while running, then man, I’m really off.
-
If I can feel gurgling in the evaporator coils, how can I have a clog if I feel gurgling liquid flowing through it?
-
Freezer runs cold great. Doesn’t this imply the compressor is working great?
any comments?
