Need to replace the main wiring "harness" that connects all electrical components

In the Maytag MHWZ400TQ01 washer model, the wire harnesses refer to the various electrical connectors and wiring throughout the machine. They connect the different components, such as the control board, motor, sensors, and other electrical parts.
To locate the wire harnesses and check them for any issues, you'll typically need to access the inner components of the washer. Here are some steps to follow:

1. Unplug the washer: Ensure the washer is disconnected from the power supply for safety.
2. Remove the top panel: Look for screws at the back of the washer holding the top panel in place. Remove these screws and slide the top panel backward or lift it up, depending on the model, to access the internal components.
3. Locate the wire harnesses: Once the top panel is removed, you should see various wire harnesses connected to different components. They are typically bundles of wires with connectors at the ends. These connectors plug into corresponding receptacles on the components.
4. Inspect the wire harnesses: Check each wire harness for any signs of damage, such as loose connections, frayed wires, or connectors not properly seated. Ensure all connections are secure and properly plugged in.
5. Repair or replace as needed: If you find any damaged wire harnesses, you may need to repair or replace them. Repairing involves fixing loose connections or re-crimping connectors. If a wire harness is severely damaged, it's best to replace it with a new one.

As for obtaining a diagram or parts list specific to your washer model, it's recommended to visit the Maytag website or contact their customer support. They can provide you with the necessary documentation or direct you to resources that can help you identify and locate the parts in your washer.
Remember to exercise caution when working with electrical components and ensure the washer is completely disconnected from the power supply before performing any inspections or repairs. If you're unsure or uncomfortable with these procedures, it's best to consult a qualified technician for assistance.

Hi David:
That is a really bad experience to have had happen. Serious sympathies to you.
I'm hoping/assuming that the fire did not destroy the entire unit and perhaps was restricted to electrical components.
I've a couple of suggestions that may be helpful.
First, I'd see if I could find a Haynes manual for the vehicle.
If I were to be faced with your situation I would probably sip a beer and ponder the engine compartment for a while. I'd try to determine if major components had been damaged, and then replace any that had been overcooked.
Most wiring harnesses have plug connections and I would try to get as complete a harness as possible from an auto salvage company.
Then, as each component was replaced or confirmed undamaged, I would try to splice or plug in the appropriate section of harness.
Reply as a COMMENT to this post if you wish to discuss more.
All the best.

Possible causes
- Oxygen sensor harness is open or shorted
- Oxygen sensor circuit poor electrical connection
- Exhaust system leak
- Faulty front or rear (pre-cat or downstream) oxygen sensor


what it means Harness is open or shorted It means that the wire(s) connected from and to the component (sensor, solenoids, actuator, etc.) is either open (cut, broken, disconnected) or shorted (touching other wires, components, body). "Open" and "short" are common electrical terms. An open is a break in a wire or at a connection. A short is an accidental connection of a wire to ground or to another wire. In simple electronics, this usually means something won't work at all. With complex electronics (such as ECMs or PCMs) this can sometimes mean something works, but not the way it's supposed to.
Circuit poor electrical connection It means that the component (sensor, solenoids, actuator, etc.) connector is not fully connected or is disconnected. Before replacing any components, try fully disconnecting the connector, reconnect and test the system or component again.
Faulty or Failed component It means that the component it's more than likely the cause of the code and that needs to be replaced
Engine mechanical problems When a code list as possible causes an engine mechanical problem, it means that the problem is not caused by electronic component, but rather by a mechanical component such as pistons, valves, mechanical pump

HI, this is a Serial communication error. This issue will more than likely concern the wiring harness.

The Communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly.

Potential Causes

• Check Wire Harness connections to the MCU, the motor, and Central Control Unit (CCU)
• Check the Drive system for any worn or failed components
• Check MCU
• Check CCU
• Check Motor
• Check Wire Harness

Replace failed component.((Usually the wiring harness will need to be replaced))

before replaceing check voltage from switch to regulator then to motor that will tell you which component is bad when you find that out look at the mounting styl off the failed component mos are held in with clips or rivets if they are riveted in you will have to drill them out

Hi,

To my knowledge, there are no onboard electrical/electronic components capable of shorting and blowing the fuse with out blowing any of the secondary fuse. The main fuse could possibly blow due to a short in the wiring or an exposed/frayed wire touching the body. The three most likely areas would be:

• wire harness leading to the regulator;
• wire harness leading to the fusebox; and/or
• wire harness leading to the ignition switch.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.
