a.

If there is continuity to Ground for

Yellow/Red (Y/R) wire with no

load, look for a short in the Sen-

sor or Y/R wire. Verify harness

connections both at the Sensor

and the Even Heat control.

b.

If the Sensor and Y/R wire are

good, replace the Even Heat

Control Assembly.

2.

If Factory Test is passed, verify

thermistor by performing test proce-

dures outlined in “Thermistor Test”.

3.

If problem persists after replacing

Moisture Sensor and thermistor,

replace the Even Heat Control

Assembly.

PROBLEM: Timer

Continuously Advances

(Refer to Timer Drawing, page 5,
and Motor Strip Circuit, page 6)

If the dryer continues to advance past

the OFF position, check the following:

–  HARNESS/CONNECTION
–  TIMER

IMPORTANT:

Electrostatic (static

electricity) discharge may cause

damage to electronic control assem-

blies. See page 1 for details.

Procedure:

1.

Verify the Blue wire and the Black L1

wires are in the correct positions:

The Black wire goes next to the Red

wire, and the Blue wire is located on

the three terminals that are close to

each other.

2.

Test the Timer by following the proce-

dure outlined in “Factory Test”, be-

ginning on page 1.

3.

If the Timer continues to advance

past OFF, then replace the Timer.
