E5: Over-Current Protection
E5 TROUBLESHOOTING STEPS:
Step 1: Check for High Voltage
Ensure that the voltage levels are within the specified range. High voltage can trigger over-current protection.
Step 2: Check for Low Voltage
Verify that the voltage levels are not below the recommended range. Low voltage can lead to increased current draw, triggering over-current protection.
Step 3: Check for Dirty Filters, Coils
Inspect and clean filters and coils. Accumulated dirt can cause the system to work harder, potentially leading to over-current situations.
Step 4: Check the Reactor
Inspect the reactor for any signs of damage or malfunction. A faulty reactor can contribute to over-current issues.
Step 5: Check the Outdoor Fan Motor
Examine the outdoor fan motor for proper operation. A malfunctioning fan motor can affect heat dissipation and lead to over-current situations.
Step 6: Check the Service Valve
Inspect the service valve for any abnormalities. A malfunctioning service valve can disrupt the refrigerant flow, impacting system performance.
Step 7: Check the Outdoor Board
Examine the outdoor control board for any visible issues or signs of damage. A malfunctioning control board can contribute to electrical irregularities triggering over-current protection.
