E3 FROST PROBE OPEN: Normal operation is allowed. Replace probe.

E4 FROST PROBE SHORT: Normal operation is allowed. Replace probe.

E5 INDOOR PROBE OPEN: Control assumes indoor ambient temperature is 90 degrees F and unit will operate. Replace probe.

E6 INDOOR PROBE SHORT: Control assumes ambient temperature is 90 degrees F and unit will operate. Replace probe.

ERROR CODES LISTING FOR “WE/WY” MODELS

E1 SHORT CYCLE SITUATION: Defined as a compressor that starts and stops more frequently than it should (more than 6 times per hour).

E2 KEYBOARD STUCK ERROR: If any key button is stuck or pressed for 20 seconds or more, the unit considers it stuck. If a key is stuck it will be ignored until released. If the “Mode” key is stuck, the unit’s function will default to Cool mode.

E3 AMBIENT (INDOOR) AIR PROBE OPEN OR SHORT: Control will assume ambient temperature is 90 degrees F when in Cool mode and 60 degrees F when in Heat mode. Unit will operate (see note below).

E4 EVAPORATOR TEMPERATURE PROBE OPEN OR SHORT: Normal operation is allowed. Replace probe (see note below).

E5 CONDENSER TEMPERATURE PROBE OPEN OR SHORT: Normal operation is allowed.

Replace probe.

E7 MOTOR OPERATION

E9 HEAT PUMP FAILURE

NOTE: All error codes display for probes open or shorted will allow unit to operate. Unit may ice up if faulty components are not replaced.

Indoor Coil Frost Probe Sensor:

Disables compressor at 30 degrees F+/- 3 degrees F. Compressor resumes operation when indoor coil temperature reaches 55 degrees F.

Outdoor Coil Frost Probe Sensor (on WY models): Disables the compressor at 30 degrees F. Compressor resumes operation when temperature reaches 43 +/- 5 degrees F.

Indoor Air Probe Sensor:

Control range is 60 degrees F to 90 degrees F +/- 3 degrees F.

REBOOT THE CONTROL PANEL

Reboot the control panel as follows: With the unit on, simultaneously hold down the Mode button and the

Temperature Arrow button for approximately 10 seconds. If the panel will reboot, you will hear the fan come on and the temperature window will read 60 degrees. If this happens, all you need to do is turn the unit off for about 10 seconds and then turn it back on to finish the reboot cycle. If the panel does not reboot, you will most likely need to replace the electronic control.
