expected. 50% above expected amps for 4
minutes.
• Indicates:
• Digital Control valve malfunction.
• Compressor, evaporator fans motor,
condenser fan motor or heater current too
high.
• Defective volt or amp meter on power
module.
• Power supply voltage too low.
• Enter Manual Function Test menu and test
(operate) each component. Check volts and
amps to determine which component has high
amp draw.
