IMPORTANT: Electrostatic Discharge (ESD) Sensitive Electronics

ESD problems are present everywhere. ESD may damage or weaken the electronic control assembly. The new control assembly may appear to work well after repair is finished, but failure may occur at a later date due to ESD stress.

■ Use an antistatic wrist strap. Connect wrist strap to green ground connection point or unpainted metal in the

appliance

-OR-

Touch your finger repeatedly to a green ground connection point or unpainted metal in the appliance.

■ Before removing the part from its package, touch the antistatic bag to a green ground connection point or

unpainted metal in the appliance.

■ Avoid touching electronic parts or terminal contacts; handle electronic control assembly by edges only.

■

When repackaging failed electronic control assembly in antistatic bag, observe above instructions.

PRECAUTIONS TO BE OBSERVED BEFORE AND DURING SERVICING TO AVOID POSSIBLE EXPOSURE TO EXCESSIVE MICROWAVE ENERGY

a. Do not operate or allow the oven to be operated with the door open. b. Make the following safety checks on all ovens to be serviced before activating the magnetron or other

microwave source, and make repairs as necessary:

1. Interlock Operation

2. Proper Door Closing

3. Seal and Sealing Surfaces (Arcing, Wear and Other Damage)

4. Damage to or Loosening of Hinges and Latches

5. Evidence of Dropping or Abuse

c. Before turning on microwave power for any service test or inspection within the microwave generating

compartments, check the magnetron, waveguide or transmission line, and cavity for proper alignment, integrity and connections.

d. Any defective or misadjusted components in the interlock, monitor, door seal, and microwave

generation and transmission systems shall be repaired, replaced, or adjusted by procedures described in service manual before the oven is released to the owner.

e. A microwave leakage check to verify compliance with the CSA should be performed on each oven prior

to release to the owner.

f. Do not attempt to operate the oven if the door glass is broken.

Diagnostics

IMPORTANT: Before powering microwave (MW) magnetron, be surethat a load, such as a microwave-safe cup of water, is present in the microwave oven cavity.

Unplug oven or disconnect power before performing thefollowing checks:

■ A potential cause of a control not functioning is corrosion on connections.

Observe connections andcheck for continuity with an ohmmeter.

■ Check all connections before replacing components, looking for broken

or loose wires, failed terminals, or wires not pressed into connectors far enough. Damaged harness must be entirely replaced. Do not rework a harness.

■ Resistance checks must be made with power cord unplugged from outlet

and with wiring harness or connectors disconnected.

IMPORTANT: Do not replace the control if there is no evidence of any failure.

To Enter Diagnostics Mode:

Before proceeding with any corrective action, perform the following steps to enter the Diagnostics mode:

1. Press “Setting”, scroll down and press “Info.” Press “Service and

Support.” NOTE: Check to see that the model number on the screen matches the

product. If it does not, then a U.I. Conguration will need to be done. If the model number does match, continue with the steps below.

2. Press “Diagnostic” for 10 seconds. Enter the password “123123123.”

Press “Enter” to conrm.

3. Press “Component Activation”. Available components depend on the

oven model. All possible components are Bottom, Ring, Light, Grill, Cavity Fan, Cooling Fan, Boiler, Drain Pump, FC Valve, Door Lock, Turn Table, and Magnetron. Each component will turn off after about 3minutes.

NOTE: Keep the Cooling Fan on when testing the Magnetron.

U.I. Conﬁguration Mode:

1. Press “Setting,” scroll down and press “Info.” Press ‘Service and

Support.”

2. Check that the model number on the screen matches the model number

on the oven model/serial tag.

3. If it does match, follow the nal steps listed in the “Final Steps” section.

4. If the model number does not match, press “Diagnostic” for 10 seconds.

Enter the password “123123123.” Press “Enter” to conrm.

5. Press “System Info”. Scroll and press “Edit Product Conguration.”

Select the correct model number.

Final Steps:

1. Plug in the oven or reconnect power and turn on the oven.

2. If it does not turn on, unplug the oven or disconnect power and repair the

cables and connections. Reassemble all parts and panels and plug in the oven or reconnect power.

3. The display must turn ON. The Whirlpool logo is shown, then the time and

date appear.

4. If the U.I. Conguration was not done, run one per the U.I. Conguration

Mode section.

5. Check that each load works correctly. If the load runs correctly, then the

issue is xed. If it does not, unplug oven or disconnect power and repair the cables and connections. Reassemble all parts and panels. Plug in the oven or reconnect power and verify oven is working.

F3 Sensors

SUGGESTED CORRECTIVE ACTION PROCEDURE

NOTE: If the temperature is above 1112°F (600°C), the sensor is considered

open. If the temperature is below -4°F (-20°C), the sensor is considered short. Be sure the oven is cold in both the cavity and electronic system.

1. Unplug oven or disconnect power. Check the sensor probe, cable, and

connector (J64 in microwave section, J62 in oven section.) Check the whole board connection harness to see if anything is loose or damaged.

2. If they are loose, t the connectors in the proper place. Replace the

harness if damaged. If they are not loose, replace the sensor.

3. Reassemble all parts and panels. Plug in the oven or reconnect power.

Make sure the cavity is cold and start a forced air cycle and preheat to 212°F (100°C). Watch the progression bar to see if the temperature rises regularly. If the temperature does rise correctly, follow the “Final Steps” section.

4. If the temperature does not rise correctly, unplug oven or disconnect

power. Replace the new sensor with the original one and replace the AM control board.

5. Reassemble all parts and panels. Plug in the oven or reconnect power

and start the cycle. If the error code does not appear, follow the “Final Steps” section. If it does appear, unplug oven or disconnect power and place the new sensor back in the oven and test it with the new AM control board.

F5 Inputs E0 Door and latch switch do not agree SUGGESTED CORRECTIVE ACTION PROCEDURE

1. Unplug oven or disconnect power, wait for 10 seconds and plug back in.

Be sure the door is closed and verify the latch system motor is running. This means the door is locked.

2. Start a Pyro function and wait 1 minute. If the error code does not appear,

the issue has been resolved.

3. If the above does not happen, check to see if the door latch is working

properly. If needed, follow the steps in the “Diagnostic Mode” section. Then run a Pyro function. If the error code does not appear, the issue has been resolved.

4. If the error code appears, unplug oven or disconnect power. Check the

wiring on the fasten connectors of the door’s motor. Plug them in if they are not mounted in the proper way. Fix or replace any that are damaged. Reassemble all parts and panel and plug in the oven or reconnect power. Follow the steps in the “Diagnostic Mode” section. If the error code does not appear, the issue has been resolved.

5. If the error code appears, unplug oven or disconnect power and use a

tester to check the micro switch functionality. The door switch contact must be an open circuit if the door is open. Latch contacts must be open if the door is unlocked. If this is not true, replace the door switch/latch component.

6. If the door switch and latch component are functional and correct,

replace the AM control board. Reassemble all parts and panels and plug in the oven or reconnect power. Follow the “Final Steps” section.
