WARNING !
WHAT TO DO IF YOU SMELL GAS:
IMPORTANT SAFETY NOTICE
The information in this service guide is intended for use by individuals possessing adequate backgrounds
of electrical, electronic, and mechanical experience. Any attempt to repair a major appliance may result in
personal injury and property damage. The manufacturer or seller cannot be responsible for the
interpretation of this information, nor can it assume any liability in connection with its use.
RECONNECT ALL GROUNDING DEVICES
If grounding wires, screws, straps, clips, nuts, or washers used to complete a path to ground are
removed for service, they must be returned to their original position and properly fastened.
IMPORTANT
Electrostatic Discharge (ESD)
Sensitive Electronics
ESD problems are present everywhere. ESD may damage or weaken the electronic
control assembly. The new control assembly may appear to work well after repair is
finished, but failure may occur at a later date due to ESD stress.
Use an anti-static wrist strap. Connect wrist strap to green ground connection point or unpainted
metal in the appliance.
- OR -
Touch your finger repeatedly to a green ground connection point or unpainted metal
in the appliance.
Before removing the part from its package, touch the anti-static bag to a green ground connection
point or unpainted metal in the appliance.
Avoid touching electronic parts or terminal contacts; handle electronic control assembly by edges only.
When repackaging failed electronic control assembly in anti-static bag, observe above instructions.
Do not try to light a match, or cigarette, or turn on
any gas or electrical appliance.
Do not touch any electrical switches. Do not use any
phone in your building.
Clear the room, building or area of all occupants.
Immediately call your gas supplier from a neighbor’s
phone. Follow the gas supplier’s instructions
carefully.
If you cannot reach your gas supplier, call the fire
department.

Caution
Trouble Symptom
Measurement Condition
When measuring power, be sure to wear insulated gloves, to and avoid an
electric shock.
No power was applied to Controller. (LED, Display off)
With Dryer Power On; Connector linked to Controller.
Check the outlet, is the voltage
110V ~ 125V AC?
YES
NO • Check the fuse
or circuit breaker.
Check if the voltage measured between
Connector “RD3- ” (Black) linked to the
Controller and “WH3- ”(White) is
110V ~ 125V?

Caution
Trouble Symptom
Measurement Condition
Before measuring resistance, be sure to turn Power off, and do voltage discharge.
(When discharging, contact the metal plug of Power cord with the Ground.)
During Diagnostic Test, tE1 and tE2 Error occur.
During operation, Heater would not turn off, or remains on.
Difference between actual and sensed temperature is significant.
After turning Power off, measure the resistance.
Check if resistance is in the range of Table 1
when measuring 6pin connector Pin
(Blue wire) and Pin (Red wire) connected
to Controller.
NO
YES
• Check if Control
and 6Pin
connector is
properly
connected.
• Replace
Controller.
Check Harness-linking connector.
Take 6pin Connector from
the Controller.
