COMPRESSOR ERROR

Cause  

Compressor failure.

Solution 

Check compressor connectors, voltage and winding values, May require new compressor or Main PCB

Compressor Ohm Values will vary based on the compressor type installed in the unit. Older heat pump dryers had reciprocating compressors while newer versions now use BLDC Compressors. Information on how to test both styles is shown below…

BLDC Compressor

The below example is for a heat pump dryer using an inverter BLDC Compressor 240Vac

Resistance : 2.56 ±0.3Ω (BLUE to RED)

Resistance : 2.56 ±0.3Ω (RED to BLACK)

Resistance : 2.56 ±0.3Ω (BLACK to BLUE)

Note: Be sure and check the wiring diagram for your specific model as wiring colors and pins could change per model.

Reciprocating Compressor

 The below wiring diagram is from model DLHX4072

Reciprocating Compressor resistance values are:

Yellow wire to Blue wire  = 1.21 ±7%Ω

 Yellow wire to White wire  = 5.04 ±7%Ω

 The voltage is 120Vac

Note: Be sure and check the wiring diagram for your specific model as wiring colors and pins could change per model.
