Low airflow. 1. Airflow is blocked. Remove any obstructions in return-air stream. Clean return-air
filter and grille. Check for crushed or restricted ducting; ducting must be as straight,
smooth and taut as possible.
2. Fan speed is set to Manual Low. If the fan speed is set to Manual Low, press and
release the Fan button until the desired fan speed and airflow are reached. If
automatic fan-speed control is desired, press and release the Fan button until the
indicator light next to the word AUTO is lit.
3. Fan Coil is iced. See below.
Fan coil is iced. 1. Thermostat set point is too low. Raise set point.
2. Improper airflow. Remove any obstructions in return air stream. Clean return air filter
and grille. Check for crushed or restricted ducting. Ducting must be as straight,
smooth and taut as possible. See the “Digital-Controls Troubleshooting” on page 15
for reprogramming options.
3. Supply air is short-cycling. Redirect supply air so that is not blowing into the return
air stream. Seal any air leaks on duct.
4. Humidity level too high. Close hatches and doors.
5. When all else fails. Switch air conditioning unit to heat until ice melts or use hair
dryer to melt.
Water coil is iced in the
Heating Mode.
Seawater temperature is below 40°F (4.4°C). Shut down system to prevent damage to
condenser. Allow coil to defrost.
System runs continuously. 1. Set point temperature is improperly set: too low for cooling or too high for
heating. Raise or lower set point.
2. Porthole or hatches open. Close all port holes and hatches.
3. Seawater temperature too high for cooling or too low for heating. Seawater
temperature will directly affect the air conditioning unit’s efficiency. This air
conditioning unit can effectively cool your boat in water temperatures up to 90°F
(32.2°C) and heat (if reverse cycle option is installed) in water as low as 40°F (4.4°C).
4. Improper air sensor location. Check your specific control troubleshooting section.

PROBLEM POSSIBLE REASON/SOLUTION
Digital display panel is not
lit.
The 8-pin display-cable plugs are not making contact (unplugged, dirty, bent, or
broken pins). With POWER OFF at the circuit breaker, remove connector and inspect. If
damaged, replace connector or entire display cable.
Fan is not running or runs
continuously.
Digital control is set for either fan cycling with compressor or continuous fan
operation. Press and hold the Fan button for five seconds to change the fan operation to
cycled (“CYC”) or continuous (“con”). Note: When configured for electric heat, after a heat
cycle ends the fan will stay on for 4 minutes even if the fan is set to cycled operation.
Fan is not running but the
compressor is.
Failed triac on circuit board. Send for repair or call local service technician.
Fan runs continuously
although it is set to cycle
with compressor.
Failed triac on circuit board. Send for repair or call local service technician.
