fault Condition Description
Indoors
Off 1 Dirty filter Clean filter,press warning/clear filter button
Off 2 Drain pan condensate fault
Condensate, check for drain blockage or
pump failure
Off 3 EPROM failure Check indoor EPROM
Off 4 Failure for ambient temperature detection Check ambient temperature sensor
Off 5 Failure for coil temperature detection Check coil temperature sensor
Off 6
Communication failure between indoor/
outdoor
Check for loose/broken connection, check
transformer
Outdoor
On 1 Failure for EPROM EPROM check outdoor EPROM
On 2 IPM Protection (component on heat sink) Replace heats ink
On 3 Over-current protection
Current exceeds maximum level or module
failure. Check
On 4 Outdoor control communication failure Check OD control wires and connectors
On 5 Compressor overload protection Module failure, replace
On 6 voltage too high or low Incoming voltage too high/low
On 7 Compressor blocked/stopped Module failure, replace
On 8 Discharge temperature too high
Discharge temperature too high, check
system air flow
On 10
Condenser coil temperature too high or
low
Check system air flow and sensor
On 11 Suction temperature too high or low Check system air flow and module
On 12
Outdoors ambient temperature too high
or low
Check outdoor ambient temperature sensor
On 13
Discharge temperature fault too high or
low
Failure for sensor or circuit detection
On 15
Communication failure (indoor or
outdoor)
Check wires, connectors, transformer
On 18 Compressor position lost, unknown Module failure, replace
On 19 Compressor position check failure Module failure, replace
On 20 Indoor coil temperature too high
Indoor coil temp too high in heating or
module failure
Outdoor
On 21 Evaporator coil freeze
Indoor coil temp too low in cooling or module
failure
On 22 High pressure switch open Check, reset high pressure switch
On 24 Compressor-over current protection Module failure, replace
On 25 Phase over-current protection
Phase over-current for compressor. Failure of
sampling
On 26 Module reset Module fault. Reset incoming field power
1. Indoor fault, warning lED flashes 1-6, other lED's off.
2. Outdoor fault, outdoor lED flashes 1-26 times. Indoor run lED turns on and indoor warning lED flashes 1-26 times.
3. While EEPROM failure on Indoor unit, all 4 lights flash.
