Code Troubleshoong Guide Possible Causes What to Do

A004 Comp.Shutdown: Discharge-Sucon Trip

Heang source defaults to elements

due to compressor malfuncon

1. Conrm fan is operaonal while

compressor is on. (If the fan is not

operaonal, check connuity from

middle(ground)terminal to either out-

side terminal. If there is a 60V or higher

reading, the fan should be running and

will need to be replaced. If not, replace

the control board (rare)).

2. Conrm lter screen is clean.

3. Inspect compressor and surrounding

components for any obvious signs of

refrigerant leak (oily residue) If the

compressor is not operaonal or there

are signs of leakage, the unit will need

to be replaced as we do not service

sealed system parts.

A005 Compressor Shutdown: Discharge Temp High

T005 Compressor Shutdown: Discharge Temp High

Heang source defaults to elements

due to low airow

A006 Sucon Temperature Too Low

Heang source defaults to elements

due to compressor malfuncon

T006 Sucon Temperature Too Low

A008 Detected Dry Fire Condion

Dry re protecon- Not sucient

water in storage tank: Heater

disabled

1. Fill storage tank with water.

2. Purge all air from the storage tank by

running a hot water faucet (This is gen-

erally an installaon issue and indicates

there is air in the tank.) If the unit is sll

displaying the A008, air is sll present

and should be purged again. Any issues

with the board or sensors would exhibit

a dierent alarm code.

T009 Compressor wiring may be faulty

Heang source default to elements

due to compressor malfuncon

1. Check connecons of the wiring and

sensors.

2. Get an Ohm reading on the thermistors

(if mulmeter is available) (See Ohm

chart for correct readings based on

ambient temperature).

3. Check on display by selecng Service--

>Sensors-->If sensor shows - 40°F, the

circuit is open. +250°F indicates the

circuit has shorted. Note: To conrm

reading, power down the unit and

unplug the thermistor from the board.

Check Ohm reading. (See ohms chart)

A009 Compressor wiring may be faulty

A101 Sucon Temperature Sensor Failure

Heang source defaults to elements

due to heat pump temperature sen-

sor malfuncon

A102 Ambient Temperature Sensor Failure

A103 Lower Heater Temp Sensor Failure

Lower tank temperature sensor

malfuncon. Heater disabled.

A104 Upper Heater Temp Sensor Failure

A105 Evaporator Temp Sensor Failure

Heang source defaults to elements

due to heat pump temperature

malfuncon.

A106 Discharge Temp Sensor Failure

A107 Water Detected on Floor: Check For Leaks Water is detected in the drain pan

1. Check for obvious water leaks (If leak is

present, service for unit leakage).

2. If obvious leakage is not present,

disconnect rope sensor from the board

and if the code is no longer present, dry

(a blow dryer is an acceptable method)

or replace rope sensor.

3. If error is sll present once the rope

sensor has been replaced, the board

will need to be replaced.

4. Press and hold the "Clear Alarm" but-

ton for 5 seconds to override the alarm

for 24 hrs.

A108 Condensate Blocked: Unclog Line

Heang source defaults to elements

due to condensate drain blockage

1. Remove top cover from tank

2. Visually inspect to ensure condensate

line is clear and there is not excessive

condensate in condensate pan

3. If water is present, locate blockage and

unlock.

4. Ask customer to where the condensate

is being routed 5. If pan is dry and no

blockage is present, replace condensate

sensor.
