HVAC LED Code Troublehsooting

In the case of HVAC technical issues please reference the flashing LED light on the interior HVAC board, and reference the flashing LED code to the chart description below.

In the event of an HVAC error please verify the number of LED flashes on the HVAC board as seen below, and compare the number of flashes to the chart below for a description of the error.

LED Flashes	Error	Description
1	Short or output over-current	The driver will alarm over current failure when the peak value of output current is larger than 30A, and stop the output. The driver will restart in 3 minutes. The driver will lock if there are more than 7 times the current within 1 hour. The alarm will clear after a power cycle.
2	Motor stall	The motor will stop the output and alarm if the motor stalls. The driver will attempt to run after 3 minutes.
3	Temperature sensor failure	The driver will shut off if the temp sensor is not detected.
4	MOSFET over temperature	Stop the output if the MOSFET temp reaches 105°c Will restart when the temp of PIM reduces to 85°c If over temp is detected the driver will stop and re-attempt after 3 minutes.
5	V_BUS low voltage	The driver will alarm - and stop the output if detected under 19v and will restore when output is over 20v for over 3 minutes.
6	V_BUS over voltage	The driver will alarm and stop the output when V_bus is higher than 33v and will restore when V_BUS is lower than 32v and last more than 3 minutes.
7	Lack phase	The driver will alarm and stop the output if disconnecting between the driver and the compressor. The drive will re-attempt after 3 minutes.
