Pioneer AC Defrost
Defrosting of the outdoor heat exchange is controlled by the microprocessor from detection from the indoor pipe temperature sensor. Defrost control type is according to the JC on the PCB whether it is connected. According to the condition, enter the defrosting operation, the first defrosting operation time is 8 minutes; after defrosting operation for one cycle, then regulate the defrosting operation time if needed. After the compressor cumulative operation time exceeds 120 minutes and the temperature of the IPT is less than 95F for 2 minutes…
When the defrosting operation time on this condition exceeds 8 minutes, it will terminate. After the compressor operates continuously for 20 minutes and the IPT is less than 73F or from the last time of defrosting operation is 50 minutes or more interval. When the defrosting operation time on this condition exceeds 10 minutes, it will terminate.
When the JC isn’t connected on the PCB = When the conditions of a) or b) is satisfied, the defrosting operation starts. Under the heating operation, the compressor cumulative operation time exceeds 50 minutes and the temperature of the outdoor pipe temperature sensor reads lower than 14F. Under the heating operation, the compressor cumulative operation time exceeds 50 minutes, if the indoor pipe temperature sensor reads lower than 104F continuously for 2 minutes.
Pioneer AC Defrost terminating conditions
The outdoor defrost sensor reads 68F the defrosting operation will terminate.
The defrosting time exceeds 10 minutes the defrosting operation will terminate.

Kirk,
It seems as if your Pioneer Inverter is displaying error codes OC and EL.
These codes typically indicate issues with the outdoor unit and the communication between the indoor and outdoor units.
OC: Outdoor unit malfunction, usually related to the compressor or fan motor.
EL: Communication error between the indoor and outdoor units.

My Pioneer Inverter stopped working and is flashing O C , E L.
I can not find what codes mean.
Our pioneer indoor AC unit just started showing the Fy Error Code.
No airflow.
Was working great before.
Can’t find that code anywhere.
Our new (to us) home has a Pioneer mini split installed in the master bedroom. I checked to see if it had the WIFI dongle installed or if I should buy one and it turns out there is no USB port. There is a small card hardwired to the main board and placed where the USB port ‘should’ be. There are a couple lights on the card which blink occasionally which leads me to believe this might be a hardwired version of the dongle. There are a couple random WIFI networks which show up when the unit is in AP mode, one is locked and the other isn’t. The ‘12345678’ password doesn’t work on the locked network and the unlocked one gets me nowhere with the Pioneer Airlink or NetHome Plus apps. None of the auto-discovery options in the apps find the unit either… Please Help!!!
Just installed a 9000 btu 115v mini split. Outside unit fan is on but the condenser isn’t kicking on. Inside unit is on and function – no error codes. Checked the voltage on the poles outside – 120v. Not sure if this is a refrigerant issue or if there’s an actual issue with the compressor pcb.
I have a WS024GMF that keeps displaying two dashes and shuts down.
