SECTION.

J.No voltage to control board.

J.Check for loose or broken wiring. Check 240/24 VAC power transformer for 24 VAC output. (see NOTE below)

K.

Inoperative compressor.

K.

Replace compressor.

L.

Temperature sensor is shorted

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 reset 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.Standard Cooling Unit with condenser coil and fan assembly-- Cooling Unit located in excessively hot area or air circulation through condenser coil is restricted.

C.Remote Rooftop Condenser Coil and Fan Assembly-- Air circulation through condenser coil is restricted.

B.Relocate unit or check and if necessary, clean air filter as instructed.

C.Check and if necessary, clean condenser coil as instructed.

D.Insufficient refrigerant charge. D. Check refrigeration system with gage set and Aurora

Series System Analyzer

(P/N 309197000). Find and repair refrigeration leak, then replenish refrigerant charge.
