If your air conditioner displays E1 in the display panel and won't turn on, it means that the Room Thermistor (a device connected to the thermostat that detects room temperature) is shorted or defective, and you need to have your air conditioner serviced.

If it displays E2, E3, or any other E error, you also need to have your air conditioner serviced.

To arrange for service, contact Samsung Customer Care at 1-800-Samsung (1-800-726-7864). Have the model number of your air conditioner on hand when you call.

You will have to find the contactor which is located in the outside unit. And check the voltage at the contactor, 26 v as this is the thermostat calling for the compressor to come on.
