7-9yo GE wine chiller, model ZDW24ABB. The light works, but the fan and the compressor will not turn on. Nothing appears loose or burnt. After much searching on the web, I learned likely prospects for failure are the temperature control, PTC relay, and the run capacitor. I tested each component with a DMM and a continuity tester. Here's what I've found...
- PTC relay shows 4.5olms resistance across 5 and 6, and shows continuity.
- Cap reads zero olms at all ranges, and shows continuity.
- Temp Control on all settings reads zero olms, and shows no continuity.
- All switches, wires, and connectors are good.
From what I've read my troubleshooting indicates that either or both the temp control and cap might be bad. (Of course, the compressor could be broken also. I haven't discovered how to test it yet--and I hope I don't need to.)
Each of these parts are very expensive so I want to be reasonably certain I am replacing a bad part before I purchase new.
Any assistance from folks experienced resolving this problem will be appreciated.

Here are your parts Replacement parts for ZDW24ABB models | AppliancePartsPros.comGE keeps all tech data a secret so the below is just general info.
- Temp Control on all settings reads zero olms, and shows no continuity. I do not understand the above. "0 ohms" is a dead short and "no continuity" is an open (infinite ohms). Most thermostats have an off position so if it read the same at off and mid-scale it is probably toast. If the thermostat is a 2 wire type, you could unplug the unit, short the two connectors together, then plug it in and give it a try. If it runs then the thermostat is the problem. I often use a bent paper clip as a shorting device, just make sure it cannot short to anything else. If necessary tape it up. |

Thank you for your response.
I shunted the temp control and the thing came to life. On one hand, I’m relieved I've identified the fault, and the problem is relatively easy to repair. On the other hand, the temp control is the most expensive of the three suspect parts I was t-shooting--over $200 from GE Appliance Parts. I purchased the part from AppliancePartsPros.com for much less, and the shipping costs were very reasonable.
Now I need to research the recommended steps to replace a temp control.
