Whirlpool Dryer Repair – How to Replace the Rear Drum Seal (Whirlpool Part # 239087)

bit to get

Hi, it’s Jack. Today we’d like to show you how to change the rear drum seal on your dryer. Over time the drum seal may dry and crack out and it allow air into your drum which will affect the drying performance.

It’s a really easy job to change.

Let me show you how we do it. Now, before we begin this repair, the first thing we’ll need to do is to disconnect the power. We’re also going to need to gain access to the back of the dryer so we’ll need to pull it forward and that may require disconnecting the exhaust fan.

So, our next step will be to remove the lint filter simply pull it out and set it aside that will give us access to two Phillips screws that secure the top to the inlet duct assembly we’ll need to remove those. Now, that will allow us to lift the main top and there are a couple of spring clips located into two or three inches from either side.

We can either use a putty knife to go into that gap and depress them or you can simply pull the main top forward while holding the cabinet just far enough that we can lift it away from them. You get that on both sides and then we can lift the main top up. Now, we’ll need to support that in some method or have somebody hold it in place.

Now, with it properly supported, our next step will be to disconnect the door switch harness. We’ll take a flat blade screwdriver, we’ll remove the little locking tabs are on both sides of that connector, you just pry that up a bit on both sides to release it. Then our next step will be to remove two, five sixteen hex head screws that secure the front panel, just hold that front panel in place.

You may need to lift up just slightly on the drum tilt the panel forward.

Then you will need to lift it up slightly to disengage two clips on the lower edges of the cabinet. Once you disengage it, you can pull that front panel away. So, when the front panel removed, our next step will be to release the tension on that belt so we’ll reach in your right hand side you’ll find the idler assembly, we’re just going to pull that towards the right side of the cabinet and that we’ll release a tension on the belt so if you roll it off with the motor pulley and the idler using the belt will then be able to lift up out of the cabinet.

Now, that we have the drum out, we can remove the old seal on the rear edge of that. Now, our next step will be to remove what’s left of the rear seal, just take a putty knife lean under the edge of that which we have the old seal removed, you can discard that. And next we’ll want to clean as much of that adhesive off particularly any areas that the adhesive might be loose and the excess felt that will be there.

So, you either using a putty knife, a wire brush, or a solvent that will soften that glue and remove it keep it as clean as you possibly can.

Now, we’re ready to put the new seal in place, so if you look at it you’ll note that there is a colored thread on one inch and two white threads in the center and opposite edge. You open it up on the back side you’ll note that there is a performed fold in place, that fold will go over the lip of the drum in that fashion. So, the right adhesive is going to be underneath the coloured thread area.

need to

Now, we advise putting the adhesive on the drum rather than trying to put it on the seal as it would be difficult to keep it from getting absorbed by the fold.

So, you just do a little at a time, place that seal on the top of the adhesive.

We’ll take a spring clamp just hold that section in place continue to feed that single around and keep some tension on it, it’s a snug fit and it will require a little bit of stretching. You have a short session done, just rotate the drum and it’s more adhesive. Carefully open that folds up and keeping some tension on it, put another clamp on and just continue to do that until you’re all the way around the perimeter of the drum.

Now, when we are reinstalling the drum, we want to make sure that the groove here sits on top of the two drum rollers and that the lip of that rear seal lays against the rear bulkhead.

So, begin by just tracking the belt around the tumbler groove side of the belt against the tumbler, lift it in to the opening and then position it on top of the drum rollers. You may need rock it back and forth a bit to get it seated it then just let it hang there. Now, our next step will be to route the belt around the idler and the motor pulley.

Now, when reinstalling the drum and the belt you need to know how that belt will fit around the idler and the motor pulley.

Essentially, the belt will come through that opening on the bottom of the idler and will wrap around the motor pulley then the crew side of the belt will wrap around the drum.

So, when we put it in the belt will be just hanging loose, we’ll pull it through that opening pull the idler over to release the tension on the belt so that it can roll it on to the motor pulley. So, reaching from below pull that belt from the right hand side towards the center locate the idler roll over the top of the idler whether it is a glide or roller and then pull it through underneath push the idler towards the right to release the tension on the belt and then roll the belt onto the motor pulley, hold that properly seated should be able to turn the drum and the motor will turn as well. And now we’re ready to put the front panel back on, we’re ready to put that front panel back on, we want to make sure that we fold that felt up because it will fit into the opening of the drum you’ll probably need to lift that drum as you position the front panel in place.

On the bottom of the front panel there are two square holes then we’ll fit over top of a hook click on both sides of the cabinet. So, we’ll engage that first making sure that the bottom edge of the front panel goes below this guard. So, just position it like that, lift up on it fit those clips into the square holes with the drum up and then push it into place so that we can attach the screws and tighten both of those screws securely, remember to reconnect the door switch harness and make sure it is fully inserted so that the locking tabs are engaged.

And now we’re ready to tilt the top down engage with the front panel, just pull slightly forward, make sure it’s hooked on both sides.

And then we’ll reinstall the two screws into the lint filter opening, reinstall the filter. We’re now ready to push the dryer back into position, reconnect even if you disconnected it and reconnect the power and our repair is complete.”
