If you experience a problem on any of the above checks, verify the fuses on the lower circuit board are
good.
If all checks prove to be good, and the refrigerator does not operate on electric mode, replace the lower
circuit board. It has been damaged by AC volts in excess of 180 volts.
LOWER CIRCUIT BOARD
A. DC VOLT: ALL TESTS ARE TO BE DONE WITH THE REFRIGERATOR IN THE COOLING MODE.
Measure volts between terminal J4 and the ground strip. Voltage should be the same as at the positive
(+) and negative (–) on the terminal block.

B. AC MODE: Check that incoming AC voltage is present at terminals J5 and J6 on the circuit board. Check
for voltage at the heating element connection terminals J7 and J8 on the circuit board. If no voltage is
present, check the 5-amp AC and 3-amp DC fuses. If fuses are good, replace the circuit board.
C. DC MODE: Check for voltage between terminal J4 on the circuit board and the ground strip. If voltage is
12.8 volts DC or above, check for DC volts between the heating element (J1) connection and the ground
strip. Check the fuses and the DC heating element.
