Hello,

This morning our Maytag washer was stuck in the door locked position and had no signs of life. Evidently we had a storm with lightning last night, my MIL noticed that the door lock light would flash on and off but didn't think much of it, this morning the door was in the locked position but seems like it has no power but we have verified the outlet it is on is working.

Is there a fuse or something that could have blown on the washer?


Thanks

Hi, I'm attaching your tech. data sheet below.

On Page 2--->First check the main control board to see if the LED is ON.

DIAGNOSTIC LED – MAIN CONTROL
A troubleshooting tool has been implemented onto the main control board—a diagnostic LED.
LED ON – The Control is detecting correct incoming line voltage and the processor is functioning.
LED OFF – Control malfunction. Perform TEST #1: Main Control, page 12, to verify main control functionality.

Here's the main control board for your model:
W11116592 Cntrl-Elec


This video gives you the general idea of how to access the main control board:


Let us know what you find.

Ok, if no LED then do TEST #1: Main Control

TEST #1: Main Control
This test checks for incoming and outgoing supplies to and from the main control. This test assumes that proper voltage is present at the outlet.

1. Unplug washer or disconnect power.
2. Remove console to access main control.
3. Verify that ALL connectors are inserted all the way into the main control.
4. Plug in washer or reconnect power.
5. With a voltmeter set to AC, connect black probe to J5-2 (Neutral) and red probe to J5-1 (L1).

If 120VAC is present, go to step 6.
If 120VAC is not present, check the AC power cord for continuity (See Figure 9).
6. Is the “Diagnostic LED” ON or OFF? (See Figure 3 below for LED location.)
--->ON: (+5VDC present) continue to step 7.
--->OFF: (+5VDC missing) proceed to step 8.
7. With a voltmeter set to DC, connect black probe to J12-4 (Circuit Gnd) and red probe to J12-1 (+12VDC).
--->If +12VDC is present, main control supplies are good.
--->If +12VDC is not present, go to step 8.

8. Check if shifter assembly is affecting the main control DC supplies.
a. Unplug washer or disconnect power.
b. Remove connector J12 from main control.
c. Plug in washer or reconnect power.
d. Repeat steps 6 and 7. Perform the +12VDC check inside header J12 on the board – do not short pins together.
--->If one or more DC voltages are still missing, go to step 9.

9. Main Control has malfunctioned.
a. Unplug washer or disconnect power.
b. Replace the main control.

Hello everyone,

Got the new control module in, mother in law installed it as I'm in the road today, the LED lights up but still doesn't work, so I have more investigation to do.

What was the TEST #1: Main Control results?

If you were not getting the +5VDC and the +12VDC in steps 6 and 7, then it says to go to step 8.

8. Check if shifter assembly is affecting the main control DC supplies.
