Mitsubishi air conditioner error code e6

Mitsubishi air conditioner error code e6

The E6 fault code appears when there is an issue with the ThIR heat exchanger sensor. This may result from resistance related to open or closed circuit. Also, there may be a disconnection on the power control board. Turn off the unit, disconnect it from the mains, check all connections, then reconnect and turn it back on.
