and ConFM energize. Cabinet temperature appears in the Display.
a)
EvapFM Diagnosis
: Confirm EvapFM energizes. If not, check for 115VAC at
EvapFM terminal connection in Brown and White wire. If 115VAC is not present,
check continuity between the Brown wire at power switch at the
“ON” position and
Brown wire at EvapFM terminal. If there is no continuity, replace the main wiring.
If continuity does exist between the Brown wire in the power switch and the Brown
wire at the EvapFM terminal, check that Evap FM is energized and fan blades turn
freely, if not, check fan blades for binding and FM winding continuity. Replace as
needed
.
b)
Controller Diagnosis
: Cabinet temperature appears on Display. If not, check for
115VAC at the controller terminals #6 (Brown) and #7 (White). If 115VAC is not
present, check power switch, power cord connections, and breaker/fuse. Confirm
wiring connections are secure. If 115VAC is present and the Display is off, replace
the controller.
