Problem Possible Cause & Corrective Action
Will Not Start or Run
• All connectors are plugged in correctly.
• Dryer is plugged into the power outlet.
• Check if house fuses or circuit breaker is blown.
• Check if the door is closed properly (if it is open, “do” will light up).
• Check if the rotary selector dial works well.
• Check if Control Board is good.
• Check if the belt is cut off or Belt Cut-off switch is initiated.
• Check if Drive Motor is spinning properly.
• Check motor winding resistance: 2.88ohms between pin #3 and 4, 3.5ohms between pin #4 and 5.
Motor runs/ tumbler will not turn• Check if the belt is cut off.
• Check if Idler Tension Spring is fatigued and get relaxed, pressing Belt S/W.
• Check if Idler Pulley is jammed or stuck.
Runs a few minutes and then stops
• Lint built-up around Drive Motor.
• Insufficient power.
• Blower Impeller stuck in Blower Housing.
5-1. Troubleshooting
5.Reference Information
Problem Possible Cause & Corrective Action
Blown Fuses
Tripped Circuit Breaker
(Electric Model)
• The amperage readings are at 240 volts. One line will be 24 amps and the other
line will be 21amps. The neutral line will be at 3 amps. If the above amperages
are present, then the house wiring, fuse box or circuit breaker could be
suspicious (faulty).
• Shorted heating element to housing.
• Incorrect wiring or wire-short to ground.
• Drive motor winding shorted to ground.
Blown Fuses
Tripped Circuit Breaker
(Gas Model)
• During ignition, the dryer will draw 7 amps. With the burner ON, the dryer will
draw 4.5 amps. If the dryer is drawing amperages roughly about, then the house
wiring, fuse box or circuit breaker could be suspicious (faulty).
• Igniter harness loose and shorted to base.
• Incorrect wiring or wire shorted to ground.
• Drive motor winding shorting to ground.
No Heating (Motor Spinning)
• Defective Heater (Open Circuit).
• Hi-Limit trips easily or is open.
• Regulating thermostat trips easily or is open.
• Membrane Switch (Open – Centrifugal S/W).
• Check Thermistor.
• Check Sensor Bars

5.Reference Information
Problem Possible Cause & Corrective Action
Will Not Dry Gas Model
Poor Gas Ignition
When the dryer is operated on a heat setting, the igniter should be energized and burner shall fire within 45 seconds at 120 VAC. The failure of a component in this system will usually be indicated by one of three symptoms:
The igniter does not glow.
If the igniter does not heat up, remove power and using an ohmmeter, check the following:
• Open Radiant Sensor (Flame Sensor)
• Open Igniter
• Shorted Booster Coil
• Open wiring
• Bad Motor Switch (Centrifugal S/W, Neutral supply)
• No power from control ( L1 supply)
No gas ignition with the igniter glowing.
If the igniter heats up but the main burner flame is not ignited, remove power and using an ohmmeter, check the following:
• Open Secondary Coil
• Open Holding Coil
• Open wire harness
• Stuck Radiant Sensor (Stuck closed)
It dies after the ignition (gas).
If a normal ignition takes place and after a short while the flame goes out, check for the following:
• Radiant sensor contacts opening prematurely.
• Weak gas valve coil may get open when being stressed by higher Temps.
• Weak Hi-Limit
• Poor venting
• Bad drum rubber seal
Problem Possible Cause & Corrective Action
Insufficient Drying
Too much wrinkle
Rough texture
Long drying time
• Clean Lint Filter.
• Remove any restriction in the exhaust system.
• Too long Exhaust Pipe (extended) or too many elbows.
• Insufficient air-intake.
• Incorrect tumbler speed due to the slipping of Tumbler Belt.
• Remove any restriction in Blower Impeller.
• Overloaded Dryer.
• Set the selection according to labels on the clothes.
• Clothes containing too much water.
Noise/Vibration
• Thumping - Check for loose tumbler baffle, worn or misaligned rear tumbler rollers, eccentric tumbler or stepped weld-seam on tumbler.
• Ticking - Check for loose wire harness or any restriction in Blower Wheel.
• Scraping - Check if front or rear bulkhead Felt Seal is out of position or Tumbler Front Bearing is worn out.
• Roaring - Check if Blower Wheel rubs on Blower Housing, or Motor Bearing is worn out.
• Popping/Squealing - Check for belt slipping.

5-10. Q & A
5.Reference Information
Q. What does it mean when chasing light appear in the display?
A. The chasing lights appear in the display when Wrinkle Prevent is selected. This lets you know that the dryer is tumbling intermittently for 95 minutes with room temperature air after the cycle is complete to reducing wrinkling. The load is dry and can be removed at any time during Wrinkle Prevent.
Q. Why is the estimated drying time so long?
A. The initial estimated drying time will be longer because the dryer has not yet detected the amount of moisture in the load. After the dryer has been running for several minutes, a more accurate estimate will be displayed. Remember, the times are estimated. The actual drying time may be longer or shorter, depending on the load.
Q. My dryer seems to run longer than I expect. Why?
A. The dryer automatically senses the dryness level of load. Be careful to avoid overloading your dryer. For best drying results, avoid mixing heavy and lightweight items in the same load.
