F&P DEGX1 Repair

[DADoES]

 
My DEGX1 SmartLoad dryer has been having a problem with throwing an airflow fault (element overheat thermostat triggering) when run on high temp.  I've been working around by running low and medium.  Last week I refurbed the matching Norgetag dryer to the Norgetag washer that I worked-over recently.  Moved the Norgetag dryer in, F&P dryer out for examination.

Here's the Norgetag.

The F&P DEGX1, 9-1/2 years old.

Top and front removed.

After rolling the drum forward to close the door, next step is remove the door grabber assembly.  F&P tries to avoid screws & bolts when possible, parts often attach with latches, tabs, or clips.  Depress the tab, lift upwards.

Drum door grabber assembly (the lid of the machine is behind it on the bench).  A small motor in the left-side bracket tilts the panel forward or back to grab or release the sliding drum door.

The tab at the left side of the panel is to manually open the drum door in case of a malfunction or power failure.  Open the lid, pull the tab forward to tilt the panel and manually roll the drum backward until the drum door comes around and is caught by the panel.

Door grabber removed.  The sticker on the drum gives instructions for opening it with the tab.

After disconnecting a few wires from the motor control board at the lower left, the inner chassis is tilted forward and out of the cabinet.

View looking from behind the cabinet to the front.

The u-shaped bracket and yoke inside it at the left is the belt idler/tension assembly.

The heat input duct can be seen at the lower/bottom left.  It mates to the heater box in the base.

View looking from front of the cabinet.

Airflow is through the heater box, up the duct on the right side, through the drum, out through the filter and duct at the left, through the blower.

Another view.

 

[DADoES]

 
Two elements.

Left/rear is 3.6KW, operates at all temp settings when the drum is running in "forward" direction.

Right/front is 1.4KW, operates on high temp (both elements) and at all temps when the drum runs in "reverse" direction.

 

[DADoES]

 
The smaller-capacity element is bad, broken in two places.

Interesting! Have never seen the inner workings of a top-loading dryer. Thanks for the step-by-step disassembly photos.

Interesting set-up and great to see how all the components work, is this the first time you have stripped the dryer down Glen?

Do the latest model of dryers still use these coil elements do you know?

Lint storage system?

Were you surprised at the amount of lint in the dryer duct system?  Granted, 9 1/2 years of daily-driver use would build up in any dryer but I would guess by your pics that you have a fairly short vent so that wouldn't be the cause.
