EVAP MOTOR OVERHEATED
•
TRIGGER–ON: One or both of the evaporator fan motor (IPEVM1 AND 2) in Compartment One circuit is
open.
•
UNIT CONTROL: Engine and standby operation: compartment 1 evaporator will shut down All other
•
UNIT CONTROL: Engine and standby operation: compartment 1 evaporator will shut down. All other
enabled compartments will continue to run.
•
RESET CONDITION: Auto Reset when motor overload input is within limits, or change to engine
operation, or alarm may be manually reset via keypad or by turning the unit off, then back on again.
NOTE: Follow the steps below until a problem is found. Once a repair or correction has been made, the active alarm
should clear itself (see reset condition above). Operate the unit through the appropriate modes to see if any active
alarm occurs. Continue with the steps below as necessary.
1.
Check Evaporator Fan Motor Contactor
a. Inspect the three contacts behind the
top cover
If the contactor buttons are blue due to chattering caused
by a defective IP, replace the contactor.
b. Check tightness of the contactor wire
connections
Tighten with screwdriver and check for discoloration of
wires.
2.
Check Evaporator Fan Motors
a. Disconnect power plug at motor
Test IP circuit for continuity using ohmmeter
If open, remove and replace motor
If closed, then an intermittent IP circuit is suspect. Check
phase to phase and phase to ground for short or open
circuits See Section 2.13.
If motor tests good, check the DC IP circuit to
microprocessor.
3.
Check Motor Operation
a. Turn the unit ON
Check current on each phase (must be less than shown
on Section 2.13).
Check voltage on each phase (must be at least 440VAC)
4.
Check Motor Operation
a. Turn the unit ON
Check current on each phase (must be less than shown
on Section 2.13).
Check voltage on each phase (must be at least 440VAC).

CHECK REMOTE DEFROST LIGHT
•
TRIGGER–ON: Defrost light current (amp) draw is higher than 0.8 Amps.
•
UNIT CONTROL: Engine and standby operation: alarm only
•
UNIT CONTROL: Engine and standby operation: alarm only.
•
RESET CONDITION: Auto Reset when Defrost light current (amp) draw is normal, or alarm may be
manually reset via keypad or by turning the unit off, then back on again.
NOTE: Follow the steps below until a problem is found. Once a repair or correction has been made, the active alarm
should clear itself (see reset condition above). Operate the unit through the appropriate modes to see if any active
alarm occurs. Continue with the steps below as necessary.
1.
Check Defrost Light
a. Inspect Defrost light & socket
No damaged or corroded pins
b. Check resistance of light bulb
Refer to Section 2.14
2.
Check Defrost Light Wiring
a. Inspect harness & control box
connector pins & terminals (See
wiring schematic)
See Notes 2 & 6
No physical damage to harness.
No damaged or corroded pins
