Safe Checks vs When to Call for Service

Before scheduling service, these basic checks can help you rule out common issues:

  • Confirm the unit has power and hasn’t tripped a breaker
  • Check thermostat or control settings
  • Replace or inspect air filters if applicable
  • Make sure vents or airflow paths are not blocked
  • Inspect door seals or gaskets for refrigeration equipment


Stop and request service if you notice:

  • Temperature continuing to rise after basic checks
  • Unusual noises, smells, or system cycling issues
  • Ice buildup, leaks, or electrical concerns
  • Commercial refrigeration not maintaining safe temperatures
  • Any issue involving refrigerant, wiring, or internal components


These steps help protect your equipment while avoiding unnecessary risk or damage.
