Section 5 Troubleshooting
5-3
Scratching or
chipping of the drum
finish.
1. Always remove foreign objects from pockets
before laundering. Remove objects from drum
and restart dryer.
2. It may be necessary to sew a scrap of material
securely around ornaments before drying to
prevent scratching and damage to the dryer.
*Drum damage caused by foreign objects or
permanently attached items is not covered by
the warranty.
Problem
Correction
1. Foreign objects such as coins,
pins, clips or buttons are inside
the
dryer.*
2. Permanently attached items such
as belt buckles, zippers and
fasteners may be hitting the
inside of the drum.*
Cause
Electrical Tests For Electric and Gas Dryers
Continuity
When measured by an Ohm meter, there should be no more than .1 Ohms resistance between the terminal block
ground and any exposed metal dryer cabinet component including control shafts and switches when probed through
or in any unpainted area.
Check continuity between motor frame and motor support bracket using a continuity light. Test light must illuminate
when probing the motor frame with one end of the test light and the motor bracket with the other. If dryer fails
continuity with a low voltage tester, check continuity using 120 VAC.
Insulation Dielectric Strength
Disconnect ground link from the neutral of the terminal block on the dryer. With the dryer completely assembled and
with the door closed, apply 120 VAC or more for one second to the terminal block terminals or service cord.
Connect one probe to all three terminals and the other probe to the backsheet. There shall be no more than 5mA of
current during the one second test interval. During the 1 second test, no drop in voltage below 120 VAC is
permissible.
Motor Power
Audit - (power required after 20 seconds with no load, motor CW direction, and no heat) 200 to 280 watts.
Line Test - (power required after 1-5 seconds with no load, motor CW direction, and no heat) 210 to 290 watts.
Low Voltage Start
The dryer motor should start and operate at 100 volts (200 volts for 230 VAC, 50Hz dryers). The power will be set to
not dip below this voltage during any part of the cycle. Increase the voltage to allow for meter error and line
fluctuations. Test the run with a 50 pound clothes load (25 pounds at 100% moisture) at “Maximum” heat setting.
Motor Protector Trip Time
When the motor is locked, the thermal protector must open to shut off motor within 3 to 10 seconds. This test also
applies to the 50/60 Hz Motor when test is conducted at 230VAC 60 Hz. Tests must be run at 120VAC (line voltage
not to sag below this value when the rotor is locked), unless specified otherwise.
Tests must be run with a cold (ambient) motor. When tested in the unit, a jumper harness will be needed to bypass
the software alarm for the motor not starting. Without the jumper, the software will stop the cycle within 3 seconds
(before the thermal protector opens) if motor movement is not detected.
