A. LINT DRAWER/LINT CHAMBER SWITCHES

1.Lint Drawer Switches

The dryer utilizes two (2) magnetic proximity switches (wired in series) to indicate a lint drawer closed status. The magnetic proximity switch is a device whereby the contacts within the device close when it comes in to close proximity of a magnetic field. If either of the proximity switches are opened, the entire circuit will be open.

The switch can be checked for failure using an ohm/continuity meter; power down the dryer and place an ohm meter across the two (2) leads that come from the switch. With a magnet in front of the switch...it should measure a closed circuit. When the magnet is removed the circuit should measure an open circuit.

a.Proximity Switch Replacement

1)Discontinue electrical service to the dryer.

2)Remove the screws securing the junction box cover.

3)Mark and identify the wires that will be removed for proper reinstallation.

4)Disconnect the two (2) leads of the defective proximity switch from the terminal block.

5)Remove cap and lock washer from the cord grip.

6)Gently pry the rubber bushing out of the cord grip.

7)Pull the proximity switch out of the bushing.

8) Replace the proximity switch.

9) Gently reinstall the rubber bushing removed in Step #6.

10)Reinstall lock washer (removed in Step #5) and reinstall the cap from grip but do not tighten.

11)Adjust the distance between the

proximity switch and the magnet to 3/8".

12) Tighten cap on the cord grip.

13) Reverse Step #4 thru Step #2.

14) Reestablish electrical service to the dryer.
