(continued)
Probable Cause
5. Motor Failure
6. Current Sense board/
function failure
7. One line of power
loss
8. Program Issue
1. System is Short on
refrigerant
2. Solenoid valve not
activating
3. Low pressure control
is Faulty.
4. Restriction is
refrigeration system.
5. Faulty wire
connection.
6. System component
failure
Remedy
5. Check motor starting components,
check motor for shorts to ground,
check for proper winding resistance.
Replace Motor as needed
6. Check current sense board wire
connections, check max current
setting in control system. (Contact
Electro Freeze Factory Tech Support)
7. Check main power supply, and
main wire connections and correct as
needed
8. Ensure U.I. Program version
and Main P.C. Program Version are
compatible. (Contact Electro Freeze
Factory Tech Support)
1. Locate refrigerant leak and repair as
needed. Ensure refrigeration system is
evacuated to at least 200 microns.
2. Determine if Solenoid coil is
receiving proper voltage (208/230
Volts), If coil is receiving voltage,
ohm out coil windings. If coil is
not receiving voltage, check relay
responsible for activating coil and
repair as needed.
3. Confirm Low pressure control is
faulty by installing manifold gauges to
confirm suction pressure is above cut-
in set point of control. Replace control
as needed
4. Locate and remove restriction i.e.
restricted drier, AXV closed down,
Solenoid valve not opening etc.
5. Repair connection as needed i.e.
faulty connection on LPCO, etc.
6. Locate failed component
(Diagnostics Mode in Technician
Menu will aid in locating) i.e. solenoid
coil, AXV valve not opening, control
relay, Compressor contactor staying
energized causing unit to pump down,
etc. and repair as needed.
