C. Evaporator coil is frozen
D. Faulty TXV
E. Condenser coil is dirty
F. Liquid line restriction (filter drier blocked, if present in system)
G. Thermostat is malfunctioning
LED on Solid
A short circuit or
over-current condition exists
on "P" terminal
Yellow “ALERT”
System Pressure Trip
1.
Flash Code 2
Discharge or suction
2.
Condenser coil poor air circulation (dirty, blocked, damaged)
pressure out of limits or
3.
Condenser fan is not running
compressor overloaded
Return
4. If low pressure switch is present:
air duct has substantial leakage
Yellow “ALERT”
Short Cycling
1.
Thermostat demand signal is intermittent
Flash Code 3
Compressor is running
2.
T ime delay relay defective, if present
only briefly
3.
4.
Yellow “ALERT”
Locked Rotor
1.
Flash Code 4
2.
Low line voltage (contact utility if voltage at disconnect is low)
3.
Excessive liquid refrigerant in compressor
Compressor bearings are seized
Hot gas sensor defective, if present
Yellow “ALERT”
Open Circuit
1.
Flash Code 5
2.
3.
Compressor contactor has failed open
4.
High pressure switch is open, if present
5.
Open circuit in compressor supply wiring or connections
Unusually long compressor protector reset time due to
extreme ambient temperature
Compressor windings are damaged
Yellow “ALERT”
Missing Phase
1. Broken wire or connector on one phase
Flash Code 6
"Lockout"
"Lockout"
"Lockout"
2. Compressor motor winding is damaged
3. Utility supply has dropped one phase
Yellow “ALERT”
Reverse Phase
1. Compressor running backwards due to supply phase reversal
Flash Code 7
"Lockout"
"Lockout"
Yellow “ALERT”
Welded Contactor
1. Compressor contactor has failed closed
Flash Code 8
Compressor always runs
2. Thermostat demand signal not connected to module
Yellow “ALERT”
Low Voltage
1. Control circuit transformer is overloaded
Flash Code 9
Control circuit < 18VAC
2. Low line voltage (contact utility if voltage at disconnect is low)
• Flash Code number corresponds to a number of LED flashes, followed by a pause and then repeated.
• TRIP and ALERT LEDs flashing at same time means control circuit voltage is too low for operation.
• Reset ALERT Flash code by removing 24VAC power from module.
• Last ALERT Flash code is displayed for 1 minute after module is powered on.
