R-290 Self-Contained Case Not Cooling
A plug-in / self-contained display case running on R-290 (propane) isn't holding temperature. These are sealed hermetic systems with a tiny charge, so most no-cool calls are airflow, condenser, or electrical — not a charge problem.
Symptoms
- Case product temperature climbing above setpoint
- Compressor running constantly or short-cycling
- Warm condenser area; evaporator not cold
