An urgent service call for a broken Samsung wall-mounted air conditioner
At AirGreen , we often receive calls from customers whose wall-mounted air conditioners suddenly stop working during the hot season. This is exactly what happened during our recent intervention in an apartment in the Côte-des-Neiges sector of Montreal . The customer, concerned to find that his Samsung unit was no longer blowing cold air, immediately contacted our team for a complete inspection.
Our technician visited the site the same day to assess the situation. The unit in question was a Samsung wall-mounted air conditioner that had been in place for over ten years, showing clear signs of aging: clogged filters, a slight damp odor, and a front panel that had yellowed over time.
Complete diagnosis of Samsung air conditioner
Upon arrival on site, our technician carried out a multi-step analysis :
-
Electrical Operation Check :
The unit no longer responded to the remote control. Upon testing, it was found that a start capacitor had failed, preventing the compressor from starting. -
Inspection of the temperature sensor and the electronic board :
The system also exhibited an intermittent error code , suggesting poor contact on the main board. This type of problem is common on older Samsung models and requires targeted soldering or replacement of faulty components. -
Internal cleaning and disinfection :
As is often the case in urban housing, dust and dirt accumulate on the evaporator. We therefore carried out a deep cleaning using a biodegradable antibacterial product, ensuring cleaner air and better performance.
The repair steps carried out by AirGreen
The repair of this wall-mounted air conditioner required careful technical intervention :
-
Replaced the start capacitor to restart the compressor.
-
Cleaning the electronic board connectors and resoldering a damaged track.
-
Tested the compressor and indoor fan to ensure voltages were correct.
-
Complete disinfection of the evaporator coil and condensate tray to eliminate all traces of stagnant moisture.
-
Reinstallation and calibration of the temperature sensor .
After these interventions, the device restarted normally and regained a stable flow of cold air , confirming that the fault was indeed due to the combined failure of the capacitor and the control circuit.
Comfort restored to the client's apartment
The customer immediately noticed the difference:
-
Fresh air was circulating evenly throughout the living room again.
-
The operating noise was much quieter after cleaning.
-
And most importantly, the indoor temperature returned to a comfortable level after just a few minutes.
Our technicians took advantage of this visit to check the pressure of the R-410A refrigerant , which was still at a correct level, a sign that the system had no major leaks.
Before leaving the premises, we reminded you of some good maintenance practices :
-
Clean the filters at least once a month.
-
Avoid leaving the “auto” mode on continuously during prolonged absences.
-
Schedule annual maintenance with AirGreen to extend the life of the system.
