How do I diagnose a seized compressor? Danby DWC283BLS
« on: September 21, 2021, 03:15:20 PM »

Hi all. I've got a used Danby wine cooler (dwc283bls) that turns on but doesn't cool.

Symptoms:
A - Digital thermometers display set temp but fridge won't cool.
B - There's also a clicking sound every few minutes, I assume from the thermal protector.
C - Dividing shelf blows air up & down, but back-wall fan in upper part of cabinet doesn't run.

Things I tried:
1 - Checked the relay and it looks intact inside (whole ceramic/metal disk). But it does get warm quickly after turning on.
2 - Bypassed the relay and thermal protector by plugging wires directly into Common and Run terminals, but compressor won't start.
3 - Left relay in place and bypassed thermal protector. Compressor won't start.
4 - Reversed polarity without relay - Compressor won't start.
5 - Reversed polarity with relay in place - Compressor seems to run, but fridge won't cool (not surprised)

I have a multimeter but don't know how to check the running amps. Can anyone help me figure out if this can be fixed? Thanks!

<Reversed polarity with relay in place - Compressor seems to run>
So you reversed hot and neutral?

It's a 3-prong compressor, so Common and Run... I think the same as neutral & hot. The start prong was powered either by the relay or I bridged it briefly with a screwdriver to get it running.

<There's also a clicking sound every few minutes, I assume from the thermal protector.>
So the compressor is going out on overload for some reason. It will do this with high head pressure, faulty winding, faulty relay, partially  or fully seized compressor.

< Reversed polarity with relay in place - Compressor seems to run, but fridge won't cool>
Reversing polarity in this situation with relay installed is exactly the same as non reversed due to AC power.

<The start prong was powered either by the relay or I bridged it briefly with a screwdriver to get it running.>
So you got the compressor running, it's not reversed.

So with compressor running, check and feel for cooling where the capillary line goes into the evaporator, is there a cooling plate inside this cooler or is it behind a panel. Listen for gas hissing, surging, liquid changes to gas at this point
