Section 8 Service Procedures Unique to Electronic Control Model Dryers
To reduce the risk of electric shock, fire, explosion, serious injury or death:
Disconnect electric power to the dryer(s) before servicing.
Close gas shut-off valve to gas dryer(s) before servicing.
Never start the dryer(s) with any guards/panels removed.
Whenever ground wires are removed during servicing, these ground wires must be
reconnected to ensure that the dryer is properly grounded.

d. Grounding Instructions
The dryer must be grounded. In the event of
malfunction or breakdown, grounding will
reduce the risk of electric shock by providing
a path of least resistance for electric current.
The dryer is equipped with a cord having an
equipment-grounding conductor and a three-
prong grounding plug. The plug must be
plugged into an appropriate outlet that is
properly installed and grounded in
accordance with all local cords and
ordinances.
DO NOT modify the plug provided with the
dryer if it will not fit the outlet, have a
proper outlet installed by a qualified
electrician.
If a positive ground cannot be established
through the power cord and if local code
permits its use, connect an external ground
wire (18 gauge minimum, available at your
local hardware store). Connect one end of the
wire under the ground screw (located at the
rear of the dryer) and the other end to a
known effective electrical ground.
If your homes electrical supply does not
meet the above specifications and/or if you
are not sure your home has an effective
ground, have a qualified electrician or your
local electrical utility company check it and
correct any problems.
e. Gas Dryers Equipped with Electronic
Control
After connecting the dryer to the electrical
supply, start the dryer (refer to the Operating
Instructions supplied with the dryer). If the
electronic control flashes (with the dryer
door closed) it could mean the polarity or
grounding of the outlet is incorrect. Have a
qualified electrician check out the polarity
and grounding and correct the problem.
Refer to Page 78.
76. SERVICE PROCEDURES FOR
TROUBLESHOOTING ELECTRONIC
CONTROL
IMPORTANT: These procedures are intended to
be used as an aid in diagnosing potential problems
with the electronic control. Refer to Section VII
(Service Helps) for diagnosing problems with
components other than the electronic control. Refer
to Figure 59 for terminal numbers, connections and
color coding.
77. DIAGNOSTIC CYCLE
a. A diagnostic cycle is built into the electronic
control to detect internal problems on the
printed circuit board of the control.
IMPORTANT: The diagnostic cycle is not intended
to diagnose any components built into the control
(i.e. relays, transformer, capacitors, etc.).
Improper connection of the equipment-
grounding conductor can result in a risk of
electric shock. Check with a qualified
electrician or service person if you are in
doubt as to whether the dryer is properly
grounded.
