Walk-In Cooler Condensing Unit Replacement at Alfonso's Pizza in Port St. Lucie

Alfonso's Pizza in Port St. Lucie reported that their medium-temperature walk-in cooler was running warm. The box was holding around 44°F — above safe food-storage temperature for a working restaurant kitchen.

• The walk-in cooler was holding approximately 44°F instead of proper medium-temperature range.
• Inspection traced the cooling failure to the condensing unit serving the walk-in cooler.
• The existing condensing unit could not be returned to reliable service and required replacement.

A failed condensing unit on the walk-in cooler left the box unable to hold temperature. For a restaurant, a walk-in running at 44°F puts refrigerated inventory at risk and forces an urgent repair decision.

• Performed on-site refrigeration diagnostics on the walk-in cooler system.
• Recovered the refrigerant from the failed condensing unit.
• Removed the failed condensing unit and set a new Tecumseh 4,100 BTU medium-temperature condensing unit.
• Reconnected the system and charged it with R-404A refrigerant.
• Started the system and verified operation and refrigerant condition.
• Measured final compressor amperage at approximately 5.5 amps.
• Monitored box temperature pull-down to confirm the repair.

• Tecumseh 4,100 BTU medium-temperature condensing unit
• R-404A refrigerant

With the new Tecumseh condensing unit in place, the walk-in cooler pulled down from approximately 44°F to 37°F. Final compressor amperage measured approximately 5.5 amps, and system operation and refrigerant condition were verified before the job was closed out.
