Common Marine Fridge Problems & Repairs
Refrigerant Leaks and Low Pressure
Symptoms: Your fridge feels warm, cycles constantly, or the unit is unusually loud. These signs often point to low refrigerant levels—usually from leaks. While DIY kits are tempting, they rarely seal leaks properly or recharge to spec.
What We Do: Our certified techs locate leaks fast using pro-grade tools, then reseal and recharge to OEM specs—right at your dock.
Electrical Malfunctions and Faulty Thermostats
Is your fridge cooling inconsistently or flashing error codes? The thermostat or control board could be to blame.
What We Do: We run full diagnostics with marine-rated tools, source reliable replacement parts, and verify system performance before we leave your boat.
Compressor or Condenser Problems
When major components like your compressor or condenser fail, it’s not a job for guesswork. These parts are expensive and vital to overall system health.
What We Do: We’ll inspect and replace worn or damaged components. If needed, we’ll rebuild systems using manufacturer specs and high-quality parts. Whether it’s a standard setup or a high-end yacht system, we handle it all.
