My x-96 has 12.3 vdc going to it, but drops to 7 vdc when unit is plugged in. HELP.....

Indoor inlet pipe sensor. Cause of error, Open/short, Solder poorly, internal circuit error.

Check point & Normal condition, Normal resistor 5 ohm at 25 C unplugged.

Normal Voltage: 2.5 vdc/ at 25 C ( plugged in )

Check Point:
1. Unplug the sensor on the indoor unit PCB.
2. Estimate the resistance of the sensor.
3. If the resistance of the sensor is 10 ohms/ 5 ohms at 25 C then the sensor is normal.
4. If the resistance of the sensor is - 0 - ohms then replace the sensor.
5. Plug the sensor on the PCB and Power on.
6. check voltage.
7. If voltage of sensor is 2.5 VDC at 25 C then the sensor is normal.
8. If the resistance is O or 5 Vdc replace the PCB.

E-02 Inverter low DC/Battery voltage shutdown Battery voltage has dropped below 10 VDC for 12-volt units or 20 VDC for 24-volt units.

• Code: 003 S97
• Description:38-VDC power supply voltage error A voltage drop is detected when a voltage drop is sensed by the IP PCB based on the signal resulting from dividing the 38-VDC resistance inside the power supply unit. The detection level is approximately 18 VDC. Voltage polling is conducted at 100-ms intervals by the IP-CPU. An error is detected when a voltage drop is sensed 10 times in succession (approx. 1 sec). No detection is performed when the interlock SW is open.

• Description:24-VDC power supply voltage error A voltage drop is detected when a voltage drop is sensed by the IP PCB based on the signal resulting from dividing the 24-VDC resistance inside the power supply unit. The detection level is approximately 11 VDC. Voltage polling is conducted at 100-ms intervals by the IP-CPU. An error is detected when a voltage drop is sensed 10 times in succession (approx. 1 sec). No detection is performed when the interlock SW is open.

• Code: 006 S97

it sounds that you have a voltage drop caused by bad wiring or a bad connection for the wiring of the trailer plug. you need to check the wiring of the trailer plug wiring back to were it connects to the truck wiring.pay attention to the condition of the plug connector itself.

The new PCB you purchased should take care of it. If you need assistance connecting the new part or the unit continues to give you trouble please contact us directly or add a comment here.

I have the same problem and it seems like it is going into thermal shutdown as ICs 104 and 106 are overheating which are fed from C138. All input source voltages seem to be correct and I do not get any voltage fluctuation from any input on the following regulator ICs. IC 106 3.3 VDC regulator is giving me 3.3VDC as a Output Source voltage and IC 104 5VDC regulator is giving me 5.0 VDC. IC102 15VDC regulator is giving 15VDC output and IC103 -15VDC regulator is constantly dropping voltage from the time of "Power On" until shutdown which takes about 5-7 minutes. I get right around -11VDC when shutdown occurs. ICs 102 and 103 are not overheating which leads me to believe that the IC 103 -15VDC regulator is faulty and putting a load on the other regulators which are trying to compensate for the voltage drop. I plan to replace the regulator with an NTE 969 replacement.
