What Does Error 50 Mean?
The Sub Zero Refrigerator error 50 indicates a malfunction of the evaporator fan, leading to excessive compressor run time and higher than normal interior temperatures. This can result from heat dissipation issues, causing the compressor to work harder than expected and potentially leading to cooling stress.
Common Symptoms:
- Compressor runs continuously
- Higher than normal interior temperatures
- Service/EC and error code 50 displayed on control panel
Possible Causes
- Excessive compressor run due to heat dissipation issues (high)
