LV Heat Pump Series

8 733 905 683 (2013/04)

LV Heat Pump Series

No compressor

operation but fan runs

Is fault LED Blinking

4 times?

Condensate fault - poor

drainage

Check condensate pan for high

water level. Check drain line for

blockages, double trapping or

inadequate trapping.

Condensate fault -

blocked return air

Check condensate pan for high

water level. Check air filter and

return air duct work for blockage.

Check that there is adequate space
between the return air opening and

walls or other obstructions on free

return applications.

Is fault LED Blinking

5 times?

Brown out fault - low

supply voltage

Check primary voltage - insure it is

within the limits listed on the unit

data plate.

Brown out fault -

overloaded control

circuit

Check control voltage - if it is below

18 V check accessories connected
to the unit and insure that they do

not exceed the VA draw shown on

page 11.

Brown out fault - bad

thermostat connection

Check that thermostat wiring is

proper gauge and length, that it is

not damaged and that all

connections at the thermostat and

heat pump are secure.

Is fault LED Blinking

6 times?

Freeze fault, air coil - no

or low air flow

Check fan motor for proper

operation.

Check air filter

Inspect air coil for dirt/debris

Check duct work - are dampers

closed or blocked?

Freeze fault, air coil -

blocked return air

Check that there is adequate space
between the return air opening and

walls or other obstructions on free

return applications.

Freeze fault, air coil - low

refrigerant

Check refrigerant pressure with

gauge set.

No fault LED -

contactor not

energized

Thermostat not calling

for compressor

operation

Ensure that the thermostat is on

and calling for "Y"

Bad thermostat

connection

Check "Y" connection from

thermostat. Insure that there is 24

VAC between "Y" and "C".

Loose wire to contactor

coil

Check wiring - insure that there is

24 VAC across the contactor coil.

Burned out contactor

coil

Test contactor with 24VAC

(between "R" and "C"). Ohm

contactor coil - an open circuit

indicates a burned coil.
