06 R-134 Compressor Current Too High (Check Alarm)

Thermo King Alarm Code

Description

Corrective Action

Compressor Current Too High (Check Alarm Occurs during Pretrip (PTI) or Function test only. Compressor power consumption is 25% above expected current draw (above approximately 13 amps); or compressor phase current level difference of 10% or more, depending on ambient temperature. Indicates: (Defective KVQ valve if CRR Model) (Defective stepper valve if CSR Model) Defective compressor or valve plate Defective volt or amp meter on relay board Inaccurate ambient, condenser or evaporator temperature measurement Out of range power supply Excessive condenser pressure due to air or wrong refrigerant in system, or refrigerant over charge

Check evaporator, condenser and ambient sensor temperatures for correct value (+/- 5 C [+/- 9 F]) by viewing Data menu. Enter Manual Function Test menu. Start and check current draw of the following components separately and together: compressor, compressor 100%, condenser fan and evaporator fan (high and low). Check volt and ampere meter. Check power supply volts.
