Safety precautions

Your safety should always be the top priority when performing any appliance repair.

• Always power off and unplug your appliance or switch off the circuit breaker before you attempt any maintenance or replacement work. This keeps you safe by eliminating any risk of electric shock. 
• If the appliance has recently been used, give it plenty of time to cool down before working on it. 
• Take your time while working to prevent accidents and personal injuries. Rushing is the enemy of precision.
• Work in a well-lit area so you can see and access appliance parts.
• Keep your workspace free of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with wet hands. Make sure the work area is completely dry.
• Check the user manual to see if there are specific installation or safety instructions related to your appliance or replacement part. 
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause personal injury.
• Wear insulated work gloves to protect your hands from sharp metal parts and debris.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Always take photos or make a note of wiring terminals or other connections before disconnecting them to make reassembly easier.
• Don’t test live voltage with a multimeter if you’re unfamiliar with how to prevent short-circuiting.
• Consider wearing safety glasses and/or a dust mask when working with chemicals, dust or a large amount of debris to prevent irritation or injury.

How to test and replace the Whirlpool range’s blower motor

Follow these steps to test the functionality of the blower motor and replace it if necessary.

Step 1. Prepare the range

1. Disconnect the range from power to avoid any electrical risks.
2. Open the oven door fully and flip up the hinge latches on both sides.
3. Partially close the oven door, lift it from both sides, and set it aside safely.

Step 2. Access the console

1. Use a Phillips head screwdriver to remove the screws securing the console.
2. Remove the console trim panel if required by your model.
3. Remove the two corner screws beneath the console.
4. Lift the console and flip it onto the cooktop.

Step 3. Run diagnostic tests

1. Reconnect the power to the range.
2. Enter diagnostic mode by pressing Cancel twice, then Start.
3. Navigate to the TEST menu using the 3 or 6 buttons and press Start.
4. Press TIMER to activate the cooling fan test and check for a capital “C” on the display.
5. Observe whether the cooling fan is running.

Step 4. Troubleshoot the fan

1. If the fan is not running, unplug the range.
2. Locate the blue P5 and red P6 connectors on the control board.
3. Disconnect the connectors and set a multimeter to read resistance in Ohms.
4. Measure between the purple wire on P5 and the white wire on P6.
5. If the reading is approximately 105 Ohms, the fan is functional.
6. If the reading is out of range or open, replace the fan.
7. If the fan is functional but does not run, replace the main control board.
8. If the fan runs in diagnostic mode but the F8 error persists, replace the cooling fan first.
9. Replace the main control board if the error persists after replacing the fan.

NOTE: Generally, for every 1 degree in temperature difference, 2 Ohms could be added or subtracted. If the temperature in your home is cooler, resistance would be subtracted.

Step 5. Remove the blower motor

1. Remove the three screws securing the rear vent trim and lift it off.
2. Lift the glass cooktop and place it on a towel or blanket for protection.
3. Remove the screws securing the back panels, anti-tip brackets, and the cooktop to the frame.
4. Swing the left-side body panel outwards, being cautious of sharp edges.
5. Locate the blower fan behind the front console.
6. Remove the screw securing the cooling fan to the console bracket.
7. Reposition the fan and disconnect its harnesses.
8. Fully remove the fan from the range.

Step 6. Install the new blower motor

1. Connect the harnesses to the new fan.
2. Secure the new fan in place with the screw.
3. Test the new fan in diagnostic mode to confirm it is working properly.

Step 7. Reassemble the range

1. Swing the body panel back into position and secure it with screws.
2. Reinstall the cooktop, rear vent trim, and all screws.
3. Flip the console back into position and attach the corner screws.
4. Clip the console trim panel back in place and install the remaining screws.
5. Reattach the oven door by sliding the hinge arms into the slots and opening the door fully.
6. Flip the hinge latches down to secure the door.
7. Reconnect the range to power or turn it back on at the breaker.
