A service call for a broken Sharp compressor
At AirGreen , we were recently called to work on a Sharp Eco Inverter air conditioner located in the Côte-des-Neiges–Notre-Dame-de-Grâce area of Montreal . This unit, known for its Plasmacluster Ion technology and its eco-friendly inverter compressor , had been providing consistent comfort to our customers for several years—until a performance issue arose at the end of the summer.
Diagnosis: a fan that no longer starts
The customer contacted us after noticing that the outdoor unit was no longer turning on , although the indoor unit was showing signs of operation. There was no cold airflow, and the unit appeared to be "frozen" despite attempts to restart it via the remote control.
Our technicians carried out a series of checks:
-
Voltage and electrical continuity test on the wiring between units.
-
Visual inspection of the main fan and outdoor condenser .
-
Reading internal error codes using the Sharp diagnostic module.
-
Checking the compressor inrush current and inverter control circuit .
The diagnosis was clear: the fan's start capacitor had lost a large portion of its capacity, preventing the motor from starting properly.
Repair and replacement of defective parts
We immediately replaced the defective capacitor with an original Sharp certified model. Taking advantage of the intervention, our team also:
-
Cleaned the condenser radiator to remove accumulated dust and debris.
-
Checked the R410A refrigerant level .
-
Tightened the electrical connections and cleaned the terminals.
-
Tested the operation of the inverter and fan at different speeds.
Upon powering up, the fan started effortlessly, and the compressor resumed stable operation. The system quickly returned the indoor temperature to an optimal comfort level.
Result: restored comfort and improved performance
After the repair, we carried out a complete performance test : the temperature differential reached 10°C again between the air inlet and outlet, a sign of normal performance . The customer, relieved, found the silence, efficiency and comfort typical of Sharp models.
We also advised the customer to perform annual preventive maintenance , to prevent sensitive electronic components, such as inverter boards or capacitors , from wearing out prematurely.
