This Page Contains Information on Earlier Versions
On earlier versions of 3-Way
models, the control panels were
built with a 2-Position AC-DC
switch. Later models have a 3-Posi-
tion switch labeled "AC-ELECTIC
STANDBY-DC". See Figure 1 and 2.
5-Amp Fuse Blows
Intermittently
Symptom:
• Blowing of 5 Amp fuse when
switching from "AC" to "DC"
or "DC" to "AC".
• When operating the refrigera-
tor in the "ELEC" mode and the
gas Ignition Switch is left "ON",
components of the relighter
can burn out when the 2-Posi-
tion switch is changed from
"AC" to "DC" or "DC" to "AC".
Possible Cause:
If the control panel has a 2-Po-
sition "AC-DC" switch, it may be
defective.
Remedy:
Replace the AC/DC (2-Posi-
tion) switch with the AC/ELEC-
TRIC STANDBY/DC (3-Posi-
tion) switch.
The replacement AC-DC Selector
Switch (61694822) has a feature
which the control panel nomencla-
ture does not indicate.
The switch has a center position
as shown in Figure 2.
The addition of the center position
provides a user convenience and
is labeled ELECTRIC STANDBY.
When operating in the electric
mode, there are occasions when
electric power needs to be tempo-
rarily shut off. (example: When op-
erating in the DC mode, an RV
makes a short stop, thereby shut-
ting down the battery re-charge
means. The user can flip the switch
to ELECTRIC STANDBY to con-
serve battery charge.)
