To Next PageTo Next PageWhat to do if the receive LED is solid green on my Daikin DM97MC Furnace?
If the receive LED on your Daikin Furnace is solid green, it might be due to a short between the data 1 and data 2 wires. In this case, you should check the data 1 and data 2 voltages.
Why is the receive LED on my Daikin DM97MC Furnace solid green?
If the receive LED on your Daikin Furnace is solid green, it could be because the data 1 and data 2 wires are reversed at the furnace, thermostat, or communicating compatible outdoor AC/HP. To resolve this, check the wire connections at the terminal block.
