IV. Service Diagnosis

WARNING

1.This unit should be diagnosed and repaired only by qualified service personnel to reduce the risk of death, electric shock, serious injury, or fire.

2.Risk of electric shock. Use extreme caution and exercise safe electrical practices.

3.Moving parts (e.g., fan blade) can crush and cut. Keep hands clear.

4.Make sure all food zones are clean after the unit is serviced. For cleaning procedures, see "VI. Cleaning Instructions."

A. Diagnostic Procedure

The diagnostic procedure is basically a sequence check that allows you to diagnose the electrical system and components. Before proceeding, check for correct installation and proper voltage per unit nameplate. As you go through the diagnostic procedure, check to assure the components energize and de‑energize correctly. If not, those components or controls are suspect. Always choose a white (W) neutral wire to establish a good neutral connection when checking high voltages. If the display module is in alarm, see "II.D.2. Alarm Safeties." For further details, see "IV.B. Control Module Check." For factory default settings, see "II.C.2.a) Default Settings."

Note: When power is turned on, the 2-hour high-temperature alarm timer is bypassed. Therefore, a high-temperature alarm can occur at startup. To silence the alarm, press and release the upper button. Alarm clears once temperature is within factory parameters.

IMPORTANT

The maximum allowable voltage variation is ±10 percent of the nameplate rating. 115VAC is used as a reference voltage when checking voltage to components. Voltage may vary depending on power supply.

1)Move the power switch to the "OFF" position.

2)Unplug the unit from the electrical outlet.

3)Remove the control box cover.

4)Plug the unit back into the electrical outlet.

5)Move the power switch to the "ON" position.

6)Confirm proper supply voltage (115VAC) to the power switch. On 3-section units, also confirm proper supply voltage to the receptacle box (115VAC for refrigerator/208‑230VAC for freezer).
