5.4 High Voltage cable
If sparking starts during trial-for-ignition, the cable is good.
If there is no sparking during trial-for-ignition: Disconnect
DC power at the refrigerator terminal block or switch unit
off. Disconnect high voltage cable from electrode. Recon-
nect DC power. If there is a sparking sound from the ignit-
er during trial-for-ignition, then replace high voltage cable
and/or electrode. On newer units the electrode and high
voltage cable are integrated into one component.
5.5 electrode
Do a visual check for cracks or breaks on the ceramic insu-
lator. A hair-line crack can be hard to see at the electrode.
The spark gap must be set at three-sixteenths (3/16”) of
an inch and tip of electrode above the slots in the burner.
When adjusting, always loosen the screw and move into
place: never try to move without loosening the screw. On
newer units the electrode and high voltage cable are in-
tegrated into one component. To acquire the proper part
always provide the product number.
5.6 control Panel
do not use the
Channel Mark 6, Model 12 E igniter.
Check for continuity between the solder joints when the
button is held down. If the control panel has continuity it is
ok. From the 4 pin connection at the control panel conti-
nuity can be tested for proper operation also.

5.7 climate control Heater
The climate control heater keeps the frame from sweating
in high humidity. Unplug the light green wire from J3 and
test for proper ohms. From the light green wire to ground
the reading should be 24 ohms +/- 10%.
