Repair Procedures
Replacing the Heater
If the heater fails to warm the air, it may need to be replaced.
Model 43 Driers have two heaters; Model 44 Driers have four heaters.
Required Items:
Screwdriver
To replace the heater:
1
Press the power switch to the
OFF
(O) position, then unplug the power cord.
2
Remove the upper white door seal, then loosen—but don’t remove—the screws
just inside the Drier door, behind the door stop (see Figure 4.1 on page 4-2).
3
Pull out and remove the front cover (Figure 4.3 on page 4-3).
4
Unhook, remove, and set aside the plenum hold-down springs, then disconnect
the thermal cut-out wires (see Figure 6.4 on page 6-12).
5
Lift the plenum and unscrew the heater from the socket. Ensure that the socket
cap is tight, then screw in the new heater.
6
Replace the plenum; ensure that the plenum and filter are fully seated. Install
the plenum hold-down springs, then reconnect the thermal cut-out wires.
7
Position the front cover, tighten the screws, then push the white door seal
into place.
8
Plug in the power cord, then press the power switch to the
ON
(|) position.
9
Test for proper operation (see page 2-4).
NOTE
#
Ensure that the proper voltage and wattage heater is being replaced into the correct
socket. For example, place the 500-watt heater in the Model 44 120V~ Drier in the right
plenum nearest the blower; the three 400-watt heaters fill the remaining sockets.
For proper operation and correct locations, see the wiring diagrams appropriate for the
device’s electrical configuration (see Appendix A).
WARNING
Electrical shock hazard when the front panel is removed.
NOTE
#
In Model 44, the left and right plenum assemblies are mirror images of one another. For
example, the thermal cut-out on the right plenum assembly is located on the back, while
that on the left is visible from the front.
CAUTION
Take care to not damage the HEPA filter. Any hole or tear adversely affects the filter
function.
