Gas Valve Testing  

Unplug connectors and test valve terminals

 

(its numbering is from the front terminal.) 

Check across terminals #1 and #3 (Booster Coil).                550 

 

Check across terminals #1 and #2 (Holding Coil).               1350 

  

Check across terminals #2 and #3 (Both coils in series).   1900 

 

Check across terminals #4 and #5 (Secondary Coil).          1300 

 

Dryer continues to run after cycle completed 

Wrinkle Prevent option provides approximately 90 minutes (20 continuous and 70 intermittent) of tumbling in 
unheated air at the end of the cycle to reduce wrinkling. Press the Wrinkle Prevent button to activate or deac-
tivate this feature. The indicator light above the pad will illuminate when Wrinkle Prevent is selected. Chasing 
lights appear in the display when the Wrinkle Prevent option is selected. The load is dry, and can be removed 
at any time during the Wrinkle Prevent cycle.

 

SUBJECT: Dryer belt slides off the pulley when 
manually rotated counter-clockwise (ccw) 

SYMPTOM: The dryer drum will not turn. On occa-
sions, the customer will rotate the drum counter 
clockwise (CCW) to check for any remaining 
clothes left in the dryer drum. By rotating the drum 
CCW, the idler arm may shift causing the belt to 
slide off the pulley. 
SOLUTION: To prevent the dryer belt from sliding 
off the pulley, the pulley has been redesigned. 
The Outside Diameter has been changed from 
22mm to 27mm.

Special Test Mode: 

Press power button & Dry level  buttons                  
simultaneously will put you in System Check Mode.. 
Display will show t2 

Press Start/Pause to toggle through the following    
operations

Do not use dryer to dry clothes which have traces of any flammable substance, such as vegetable oil, cooking 
oil, machine oil, flammable chemicals, thinner, etc., or anything containing wax or chemicals, such as mops 
and cleaning cloths. Flammable substances may cause fabric to catch fire by itself.

 

Make sure the idler pulley and the 
motor pulley are straight in line 
with each other, bend to correct 

Service Test Mode: 

How to Enter: To enter Service Mode , press Temp + Signal for 3 sec-
onds, until it sends out a beeping sound 3 times
