This guide helps you decide whether the issue is energy source, ventilation, operation conditions or a dangerous cooling-unit failure.
Know the energy source
Propane and electric modes both add heat to the cooling unit. A failure on one mode but not the other helps isolate the path.
Respect leveling limits
Operating far outside manufacturer leveling limits can damage cooling performance and the cooling unit.
Ventilation is part of the appliance
Heat must rise through the rear compartment. Missing baffles, nests or dead fans can ruin hot-weather performance.
Thermistors and door seals
A misplaced thermistor, overpacked shelves, frost or weak gasket can leave the food section warm while the freezer looks acceptable.
Danger signs
Ammonia odor, yellow residue and overheating faults are not normal maintenance problems. Stop operation and arrange service.
Keep troubleshooting

When to call a professional
Use refrigerator service for cooling-unit leaks, gas burner work, control-board testing, heating element replacement, recall questions or repeated overheat faults.
