Introduction
Go to step 1 ↓If a Speed Queen TC or TR Series washer won’t run correctly, the main control board may be failing. Replacing the control board can fix issues like nonstop beeping you can’t cancel, all the lights flashing and the washer only working briefly after unplugging, or no drain-and-spin even though the other components are working. This guide uses the TC5 as the example, but the access and replacement process is similar on the TR-3, TR-5, TL-3, and TR-7.

Step 1 Confirm the problem and get the correct board
-
Replace the control board if the washer beeps nonstop and won’t cancel.
-
A failing board can also cause all the lights to flash, prevent drain and spin, or let the washer work only briefly after being unplugged.
-
Flashing wash, spin, and lid-lock lights in sequence can also point to a failed control board.
-
Order the board that matches the exact washer model, because each model uses a different board.

Step 2 Unplug the washer and prepare the work area
-
Pull the washer forward so you can comfortably access the front and lower edge.
-
-
Step 3 Remove the front panel screws
-
Use a 5/16 inch nut driver to remove the two screws at the bottom of the front panel.
-
Remove the left screw and the right screw, and set them aside.
-
-
Step 4 Remove the front panel
-
Pivot the front panel away from the washer so it swings out and drops down from the bottom edge.
-
Pull the panel away from the cabinet to access the inside of the washer.
-
-
Step 5 Remove the control board assembly
-
Locate the control board assembly in the lower left corner of the washer.
-
Find the board inside its plastic housing on a metal mounting bracket.
-
Use a 5/16 inch nut driver to remove the screw securing the metal bracket to the chassis.
-
Lift the board assembly up to free it from the chassis, and pull it out where you can work on it.
-
-
Step 6 Open the board housing
-
Use a 5/16 inch nut driver to remove the three screws holding the plastic cover to the metal backing.
-
Remove the two screws on the front of the cover and the one screw on the back of the cover.
-
Lift off the plastic cover to expose the circuit board.
-
-
Step 7 Disconnect the wire harnesses
-
Depress the locking tab on a wire connector, and pull the connector straight off the board.
-
Repeat for all wire harness connectors until the board is fully unplugged.
-
-
Step 8 Remove the old board
-
Pull the board assembly away from the main wire harness trunk once all connectors are unplugged.
-
-
Step 9 Install the new board and reconnect the harnesses
-
Attach each wire harness connector to the matching socket on the new board.
-
Match connectors by their pin counts and shapes, and don’t force a connector into place.
-
Press each connector in until it’s fully seated and snug with no loose connection.
-
Route the wire packs the same way they were originally routed so the board will fit on its mounting bracket.
-
-
Step 10 Reinstall the board cover and secure the assembly
-
Set the plastic cover back onto the board housing in the same orientation as it was originally.
-
Route all wires through the gap on the lower right side of the cover so they can exit to the main harness trunk.
-
Use a 5/16 inch nut driver to reinstall the three screws that secure the plastic cover to the metal backing.
-
-
Step 11 Reinstall the board assembly in the washer
-
Slot the metal tab on the board bracket into the washer chassis.
-
Use a 5/16 inch nut driver to reinstall the chassis screw that locks the board assembly in place.
-
-
Step 12 Reinstall the front panel
-
Hook the front panel’s metal clips into the notches in the top lip of the washer opening.
-
Pivot the front panel into the cabinet so it rotates into place and the clips lock in.
-
Seat the two front-panel pegs into their matching holes so the panel sits flush.
-
Use a 5/16 inch nut driver to reinstall the two screws at the bottom of the front panel.
-
-
Step 13 Restore power and test the washer
-
Plug the washer back in.
-
Run the washer to confirm normal operation.
-
-
If the washer still won’t operate correctly after replacement, recheck every connector for a fully seated, snug fit, and confirm the wiring is routed through the cover’s lower-right wire gap without being pinched. Make sure the installed control board matches the washer’s exact model. Repair didn't go as planned? Ask our Answers community for help.
