Wine Cooler Condenser was Clogged

On 2/2/2023 On arrival I checked in with the owner. Owner turned off the wine cooler because it was not cooling. I turned it on, then found that the Wine Cooler condenser was clogged, I cleaned it . Then turned it on and went to lunch in order to let the unit cooling. Coming back found the unit at 62°-64° Set point is 54°. I called tech support and since the unit was off, they want us to allow the unit running for at least 48 hours. Cooler is working within the wine temperature range of 50°-65°. Owner agreed on coming back later to keep troubleshooting the walk-in cooler in Austin Texas.
