Compressor Start-up Error

¿Qué significa E59 ?

The compressor has failed to start properly, which can be due to electrical issues, mechanical binding, or control problems. This prevents the system from generating cooling or heating capacity.

• Compressor unable to start within the specified time or torque.
• Low voltage supply to the compressor motor.
• Mechanical binding within the compressor.
• Incorrect starting capacitor or relay operation.

1. 1

   Verify the power supply voltage to the compressor terminals, checking for correct phase voltages and balance.

2. 2

   Check the compressor windings for proper resistance across U-V, V-W, U-W phases to detect open or short circuits.

3. 3

   Inspect the compressor contactor and associated control wiring for proper operation and secure connections.

4. 4

   Listen for any unusual noises from the compressor during a start attempt, such as humming or grinding, indicative of mechanical issues.
