TECHNICAL MANUAL for IBIS ROOFTOP CARAVAN

AIRCONDITIONER

ERROR CODES & THEIR MEANING:

E1: Room sensor fault. Usually a faulty connection (plug), damaged lead or a faulty sensor

itself.

Action: Check White plug is connected on main board.

Check resistance of thermistor & cable by measuring

with a multimeter. 10K ohm @25C. See g 19 and table 1.

If open circuit or out of calibration, replace.

E2: Inside coil sensor fault: Usually a faulty connection (2 plugs)

Damaged lead or faulty sensor.

Action: Check Yellow plug is connected on the main board. And also plug in

bundled wiring near the coil.

Check resistance of thermistor & cable by measuring

with a multimeter. 10K ohm @25C. See g 19 and table 1.

If open circuit or out of calibration, replace.

When replacing this thermistor, install such that cable is downward from

the copper pocket on the coil. See g 18

E3: Outside coil sensor fault Usually a faulty connection (2 plugs), damaged lead or

faulty sensor.

Action: Check Red plug on main board and extension plug in

bundled wiring usually located near capillary tube coils.

Check resistance of thermistor & cable by measuring

with a multimeter. 10K ohm at 25C. See g 19 and table 1.

If open circuit or out of calibration, replace.

E4: Indicates lack of refrigerant, or the compressor is not running, or the thermistor is out of

calibration.

Action: Check that the compressor is running by listening.

If it is apparent that the compressor is running, then check the

temperature difference across the evaporator.

i.e. Measure temperature of return air at inlet lters and

measure temp. of discharge air at grilles. This temp diff.

should be 14 to 18 C. with fan on hi speed. If temp diff. is less than this,

suspect lack of refrigerant.

Fit a suction gauge to access valve at rear of unit. See g 12. On a 35C

outside temp. then suction should be 380 to 450Kpa.
