When checking inverter voltage output, connect 
the test-meter leads to any 2 of the 3 compressor 
lead wires at the inverter plug (plug should be 
connected). The same reading should be measured 
between any 2 of the 3 wires.

The inverter controls compressor speed by 
frequency variation and by Pulse Width Modulation 
(PWM). Changing frequency and PWM will cause 
an effective voltage between 80 and 230 VAC to be 
received at the compressor.  

•  Low speed (1710 rpm) - 57 Hz

•  Medium speed (2100 rpm) - 70 Hz

•  High speed (3120 rpm) - 104 Hz

The inverter receives commands from the main 
control board. The main control board will send 
a PWM run signal from the J15 connector of 
between 4-6 VDC effective voltage to the inverter 
(all wires must be connected). The inverter will select 
compressor speed (voltage output) based on this 
signal. 
The main control board will only send a run signal to 
the inverter when the compressor should be on.

Note:

 When measuring signal voltage (from the 

main control board) at the inverter, a reading  of 4-6 
VDC will be measured with all wires connected. If the 
inverter wiring is disconnected, the board output will 
measure between 10-12 VDC.
The inverter will monitor compressor operation 
and if the compressor fails to start or excessive 
current draw (4 amps maximum) is detected, 
the inverter will brie

fl

 y stop voltage output.  The 

inverter will then make 12 consecutive compressor 
start attempts (once every 12 seconds). After 12 
attempts, if the compressor has not started, an 8-
minute count will initiate. After the 8-minute count, 
the inverter will attempt to start the compressor 
again. If the compressor starts, normal operation 
will resume. If the compressor fails to start, this 
process will be repeated. Removing power to the 
unit will reset the inverter count. When power 
is restored, the inverter will attempt to start the 
compressor within 8 seconds. 

The inverter has a built-in circuit protection to 
guard against damage from a failed or shorted 
compressor. However, if a failed compressor is 
diagnosed, order a new compressor and inverter.  
If the compressor fails to start after replacement, 
replace the inverter.

Inverter Compressor

Caution:

 Do not attempt to direct-start the 

compressor. The compressor operates on a 3-phase 
power supply. Applying 120 VAC to the compressor 
will permanently damage the unit. It is not possible 
to start the compressor without an inverter.

The compressor is a reciprocating, variable speed, 
4-pole type. It operates on 3-phase, 80 to 230 VAC 
within a range of 57 to 104 Hz.  

Note:

 Certain voltmeters will not be able to read 

voltage output or frequency from the inverter.

Compressor wattages at various speeds are: 

•  LOW - 65 watts 

•  MED - 100 watts

•  HIGH - 150 watts

The compressor is controlled by the inverter, which 
receives its signal from the main control board. 
Varying the frequency to the inverter changes the 
compressor speed.

Compressor speed is based on the temperature 
set point in conjunction with the speci

fi

 c cabinet 

temperature. Speeds are selected according to 
the following cabinet temperatures, with freezer 
temperature being the primary:
•   7°F to 19.5°F above freezer set point = high 

speed.

•   4.5°F to 6.5°F above freezer set point = medium 

speed.

•   1°F to 4°F above freezer set point = low speed.
•  1°F to 2.5°F above refrigerator set point = low 

speed.
