Name
Cause
Solution
Recirculating material to
heat with drum feed pumps
only.
Recirculate material using
Jog mode for heat exchanger
heating.
Coolant circulation pump
not working.
Check for 240 VAC on pump.
If there is the correct voltage,
replace circulation pump. See
Replace Circulation Pump,
page 78
.
Air lock in circulation pump. Check for coolant flow in sight
glass.
Loose or incorrect wiring
connections.
Verify coolant valve con-
nections, see
Electrical
Schematics, page 134
. Check
coolant valve harness (D).
See
Harness Identification,
page 134
. Verify voltage is
11–13 volts at coolant valve
connectors.

No voltage to coil of
valve.
Turn on the manual valve
switch, on the load center,
to manuallyturn on the
solenoids and see if the
temperature rises. If
not, check voltage output
on J6 connector on the
load center (242) and
ensure the LEDs are on.
See
Load Center, page 143
.
Follow
Load Center
Diagnostics, page 37
. If
necessary, replace the
load center board. See
Replace Load Center, page 64
.
If voltage is present, measure
the resistance of the coil, it
should be approximately 12.5
Ω, if coil is open replace coil.
If voltage is present, test the coil
withscrewdriver. The screw-
driver should magnetically stick
inside the coil. If screwdriver
sticks, then the coil is good.
Replace the plunger on valve
or replace the complete valve
assembly. See
Replace Control
Valve, page 77
