# How to Fix Maytag Error F39 (Relay Failure)
The F39 error code on a Maytag washing machine points directly to a critical electrical failure, specifically related to the machine’s ability to switch power to key components. This is rarely a simple fix and almost always requires replacing the central electronic component.

## 1. Explanation: What This Code Means
The F39 code signifies a **Relay Failure**.
Relays are electromagnetic switches located on the Main Control Board (sometimes called the CCU or MCU) that are responsible for turning high-power components on and off—such as the motor, the drain pump, the heating element, or the door lock.
When the washing machine attempts to activate one of these components, the control board closes a relay. The F39 error indicates that the control board failed to receive the expected feedback or confirmation that the relay successfully switched power.
**Likely Culprit:** Since the relays are soldered directly onto the Main Control Board, the failure usually means the entire board must be replaced.

## 2. Step-by-Step Fix: How to Diagnose and Resolve F39
Before assuming the worst, it is crucial to perform a basic power reset to clear any temporary electronic glitches.
### Step 1: Perform a Hard Reset (Required)
Sometimes a transient voltage spike can confuse the control board, leading it to incorrectly register a relay failure.
1. **Safety First:** Unplug the washing machine completely from the wall outlet. Do not simply turn it off.
2. **Wait Time:** Leave the machine unplugged for a minimum of 5 minutes. This allows the internal control board capacitors to discharge completely, effectively “clearing” the memory.
3. **Plug In:** Plug the machine back into the outlet.
4. **Test:** Attempt to start a new, short cycle (like “Rinse and Spin”).
*If the F39 code returns immediately, proceed to Step 2.*
### Step 2: Check the Drain Path and Filter
While F39 is a relay issue, a severe blockage that prevents the drain pump relay from completing its circuit can sometimes trigger this specific code on older or specific Maytag models.
1. **Access the Drain Filter:** Locate the drain pump filter, usually behind a small panel at the bottom front of the machine.
2. **Drain Water (If Present):** Place a shallow pan and towels nearby. Slowly unscrew the cap to drain residual water.
3. **Clear Debris:** Pull out the filter and inspect it for lint, coins, socks, or foreign objects. Clear any blockages.
4. **Test:** Replace the filter cap securely and attempt a test cycle.
*If the F39 code persists, the Main Control Board is confirmed to be faulty.*
### Step 3: Replacing the Main Control Board (The Primary Solution)
Since the relay itself is not a user-serviceable part, the entire Main Control Board must be replaced.
**A. Identify the Correct Board:**
* You must locate the specific **Model Number** and **Serial Number** of your washing machine (usually found around the lip of the door opening or on the back panel).
* The exact control board required depends entirely on your specific model variation. Ordering the wrong board can cause further electrical issues or the new board may not work correctly.
**B. Control Board Replacement Procedure (General Steps):**
1. **Disconnect Power:** Unplug the washing machine from the wall (absolutely critical).
2. **Access the Board:** Depending on your model, the control board is accessed by removing the top panel (common on front-load models) or the rear access panel.
3. **Document Connections:** Before unplugging any wires, take multiple, clear photographs of the wiring harness connections attached to the old control board. This ensures correct reassembly.
4. **Remove the Old Board:** Disconnect all wire harnesses and screws/clips holding the old board in place.
5. **Install the New Board:** Secure the new board. Reconnect all wiring harnesses exactly as documented.
6. **Reassemble and Test:** Replace the access panel(s). Plug the machine back in and run a diagnostic or test cycle to confirm the F39 error is gone.

**Note on Programming:** Some newer Maytag control boards are “universal” and require a small programming step (usually involving setting a specific jumper or downloading a configuration file) after installation. Consult the documentation provided with your new replacement board.
