Diagnostic Tests

IMPORTANT: The following procedures may require the use of needle probes to measure voltage. Failure to use needle probes will damage the connectors. To

ease the process of measuring voltage and resistance, test points for each pin are accessible through the slots in the plastic beneath each CCU connector.

Test Name Description Steps

TEST #1

Main Control

(ACU)

This test checks for incoming and

outgoing power to and from the

main control. This test assumes

that proper voltage is present at

the outlet.

Example:

■ 14 VDC output from ACU

1. Unplug range or disconnect power.

2. Remove door and toe panel to access main control.

3. Verify that ALL connectors are inserted all the way into the main control.

4. With a voltmeter set to AC, connect black probe to J5-2 (Neutral) and red probe to J5-1 (L1).

5. Plug in range or reconnect power.

■ If 120 VAC is present, unplug range or disconnect power and go to step 6.

■ If 120 VAC is not present, unplug range or disconnect power and check the AC power cord

for continuity.

6. Disconnect P9, use a voltmeter set to DC, connect black probe to P9-1 (GND) and red probe to

P9-5 (+14 V) on the board. Plug in range or reconnect power. If DC 14 V is not present, unplug

range or disconnect power and change main control. If DC 14 V is present, unplug range or

disconnect power.

7. Reassemble all parts and panels. Plug in range or reconnect power.
