Replace part 3405281 - Kenmore Dryers

  • shockda Dec 13, 2009

    I have a Kenmore Elite Electric Dryer.

    Dryer only runs (drum turns and air flows) when pushing start button.

    Shuts off when start button is released.

    While holding this start button to run dryer no heat is produced.

    Checked heating element for Continuity(yes) and any Shorts(no).

    Checked Thermal fuse (has continuity)

    Checked high-limit thermostat (also has continuity)

    Checked voltage coming in and each line to ground have 124V to ground and 240 across lines

    the only thing thats unusual is the fact that the start button pushes in starting as normal but when released the dryer shuts down.

    All ducting are clean and free flowing.

    This is really a puzzler and any help would be greatly appreciated.

    Thanks in advance-ShockMan

The problem is with the two relays, heater relay and the motor relay, both of which are identical relays. If the motor relay is broken, you have the switch problem. If the heater turns on and then goes off for several minutes or longer, it is the heater relay.

You can order two relays if needed, using the part number, Potter & Brumfield part number T9AP1D52-48-03, costing about $4 per relay versus $25-$40 if you use the Kenmore part number 3405281. Jameco is a good supplier.

If you need both order 4 since it will probably go bad again. Keep spares at $4 a pop. It is worth it.

My Kenmore Elite gas dryer, model 110.73932192, only runs when I hold the start button. If I let go, it shuts off. What's going on?


The first thing to check on that is going to be the relay for the motor and see if its not working as supposed to. Th easiest way to check that is temporarly swap it with the one for the heat which is identical to the motor relay. Both can be found in the control panel next to each other. The way to tell them apart is the BIG HEAVY WIRES on the one for the motor the wires are going to be blue and on the heater relay the the big wires are going to be RED.The picture shows what the relays look like and it will indicate what i mean as big wires because will they go ill circle in red. A tip to swap the two is use your cell phone/digital camera and take picture first so ya jnow where the wires go.oldtech2332_8.jpgThe part # is 3405281

it could be purchased at your local appliance parts store or online at;

I hope i have been able to help you determine why your dryer wont run,

Kenmore Elite dryer start button turns off after 2 seconds

Hi and welcome to FixYa, I am Kelly. This is often caused by the relay inside the control panel.

If you don't have heat or the motor stops as soon as you let go of the PTS (push-to-start) button, there is a quick test you can do to see if it is a bad relay. There are two identical relays inside the control panel: one for the heater circuit (#15) and one for the motor control (#36). They are both part number 3405281.
  • Unplug the dryer.
  • Identify the two relays. Looking at the panel from the front, the heater relay is just to the right of the circuit board, and the motor relay is just left of the PTS button and at a slight angle. You probably want to label and/or diagram which wire goes onto each of the spade lugs.
  • Remove the wires, unscrew the relays and switch them.
  • Ensure that nothing is going to short out and plug in the dryer.
  • Set fabric selector to High and the timer to Timed Dry past the 10 minute mark
  • Press the PTS button and release it.
What you are looking for after the changing relay positions:
  • If you had motor-stops problems before, but now it continues to run but with no heat, you almost certainly had a bad motor relay.
  • If you had motor-runs-but-no-heat problems, but now the motor stops, had a heater relay problem. Try holding the button in for 10 or 15 seconds and observe the heating element. If it starts glowing, the heater relay failed.
The replacement relay can be found via these sources: (It pays to net search!)

Kenmore elite dryer 11063942101 works if I force the switch to stay in the on position but won't start by just pressing the switch. Replaced pust-to-start switch. Same problem. Vacuuming out the areas...

The problem is definitely not the motor but rather the motor relay or the electronic control. Either the motor relay is not working to close the motor circuit or the electronic control is not powering up the motor relay to serve its function.

The motor relay and the heater relay are identical and can be used interchangeably. The heater relay may be used in place of the motor relay if the dryer heats up when the start switch is held on. It indicates that the heater relay is working.

Disconnect power to the dryer then pull the end cap trims off then remove the control panel securing screws. Once the screws are removed, rotate the control panel up to the rear of the dryer.

Disconnect the wires and remove the relays then put each in the place of the other. Refer to the component layout diagram for the location of the relays.

Reconnect the wires then rotate the control panel down back into position then plug the dryer in and start it. The dryer should start and continue to run when the start switch is released since the working heater relay is used but will not heat up indicating that the motor relay is not working. Otherwise the fault is in the electronic control.

Replace the faulty component and it should address the problem. The relay (heater/motor) is part number
3405281 and the electronic control is part number W10116565.

Squeeze on the electronic control mounting bracket as shown then pull the board up to remove.

Insert the new control board and gently press it down into position. Transfer the wires from the old board to the new board one at a time.

Simply unscrew the relay to be replaced then secure the new one into position and transfer the wires.

Rotate the control panel down and secure it back into position to complete the repair.

Kenmore model:110.62974100 not heating. Tested heating element, thermal cut out, hi limit thermostat,and 220 at the outlet. All tested good. What am i over looking?

What you have not tested is the heater relay located behind the console. Disconnect power to the washer then remove the screws attaching the console rear panel to the console. The are two relays behind the console; the one with the red wires connected to it is the heater relay while the other one is the motor relay. Clean the heater relay terminals and ensure a snug fit connection then plug and start the dryer.

The relays are identical and can be swapped out; swap them out when the dryer still doesn't heat after the terminals are cleaned. Just make sure to label the wires and mark the terminals.

Replace the electronic control board, part number 3976627, if the dryer runs and doesn't heat after the relays are swapped out. Replace the heater relay if the motor doesn't run after the relay swap. The relay is part number 3405281.

The 3405281 relay burnt out. I replaced and the dryer still will not run unless I hold the start switch

It doesn't work at all If your dryer doesn't work at all, it could be because of problems with: Power from the house Door switch Thermal fuse Wiring Power from the house Check to see whether there's power getting to the dryer. Is it plugged in? If you plug something else into the outlet, does it work? If not, check for a blown fuse or tripped circuit breaker. Door switch If the door switch or the door-switch actuator is defective, the dryer won't work and you need to replace the failed component. The switch is inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. Thermal fuse On many dryers, there's a thermal fuse (a heat-sensitive fuse that blows if the dryer overheats) mounted to the exhaust duct inside the back cover panel. The fuse is about an inch long. It's usually embedded in black resin and mounted in a white plastic housing.

If the fuse has blown, it has no continuity. When this happens, your dryer either just stops heating, or it doesn't work at all. Be sure to inspect the venting/heating system before replacing the fuse to put the dryer back into operation. (You can't re-set this type of fuse.)
Wiring Often the main wiring connection from the house, at the dryer, burns and the connection breaks. In this has happened to your dryer, you need to replace the power cord and the terminal block inside the dryer to which the wire is attached.

My Kenmoor dryer will not start. When pushing the

send model number, an even heat board would cause this,or you can unplug dryer and open console on top and see if the even heat board is in there,check it for burn marks,there should be a tech sheet in the console that will help you out but put it back,if you have to call someone in to work on your dryer and the tech sheet is gone they might not be able to help you, there is a relay part 3405281 could be in there,there are actually two of them,there is a heat relay and a motor relay,you can change them out as they are the same part and see if motor stays running,if so change out the motor relay, but i need model number to look up your dryer

The dryer worked then we moved it and replaced the cord. now it does not work. it will start but only runs if you hold the button down

The Model # would help to answer this. Is it an evenheat dryer. Should say evenheat above the timer. If it is it will have a computer panel inside the control panel that may need replacing. You will usually see a burnt resistor on the board. If it is not an evenheat dryer, than youmost likely have a bad relay inside the control panel. There are 2 relays. One is the motor relay and one is the heat relay. The heat relay will be the problem. Part # 3405281. I believe its the relay on the right, but cant say for sure without a model #. To check, the easiest way is to order yourself a new relay, theyre cheap. Unplug the old relay and plug in the new one. If it works your set, if not try the other relay. Theyre both the same part, just for a different source. If you have anymore questions you can contact me through my forum at, thanks
