Trouble

 

Probable Cause

 

Remedy

COMPRESSOR DOES NOT

J.

Inoperable control board

J.

Replace control board.

OPERATE (con’t).

 

 

 

 

 

K.

Inoperable contactor

K.

Replace contactor.

 

L.

No voltage to control board.

L. Check for loose or broken wiring.

 

 

 

 

Check 240/24 VAC power

 

 

 

 

transformer for 24 VAC output.

 

 

 

 

(see NOTE below).

 

M.

Inoperable control board or

M.

Replace control board.

 

 

water/ice sensor PC board.

 

 

 

N.

Inoperable ICE SENSOR.

N.

Replace ICE SENSOR.

 

O.

EVAP IN, COND OUT, or

O.

Replace inoperable sensor.

 

 

EVAP OUT sensor is open,

 

 

 

 

shorted, or out of temperature

 

 

 

 

range.

 

 

P.Hydro Boostâ WATER SENSOR is shorted or open circuit.

P.Check for loose, broken, or disconnected wire or plug at pre-cool coil. Repair or replace wire or secure plug. If Hydro Boostâ WATER SENSOR is inoperable, replace sensor.

NOTE: Confirm which sensor has failed by using the Aurora Series System Analyzer (P/N 309197-000).

NOTE: The 240/24 VAC power transformer has an overload reset button located on its 24 VAC output side (see Figure 3). An overload on the transformer will cause its reset button to pop out disrupting the 24 VAC output to the main control board. Overload button must be pressed in to restore 24 VAC output.

COMPRESSOR OPERATES

A. Cooling capacity is exceeded

CONTINUOUSLY BUT DOES

by overdrawing.

NOT FORM SUFFICIENT ICE

 

BANK

 

A.Reduce amount of drinks drawn per given time.

B. Air circulation through Remote

B. Check and if necessary, clean

Condenser Coil and Fan

condenser coil as instructed.

Assembly Condenser Coil is

 

restricted.

 

C.Insufficient refrigerant charge. C. Check Cooling Unit sight glass for bubbles or liquid break. Find and repair refrigeration leak, the replenish refrigerant charge.

D.Inoperative or disconnected pulse-modulating expansion valve (see REFRIGERATION FLOW DIAGRAM).

D.Check that expansion valve is operating by touch (should be able to feel valve pulse).

Check for loose or disconnected wire to solenoid coil. If necessary, troubleshoot expansion valve with a gage set to see if it is opening. If expansion valve is not opening, suction pressure will be in a vacuum.
