I have a Lily space heater and it runs a few minutes and cuts off; then I get an E3 on the heater. I don't know what it means.

Since we do not know if your heater is new or used or if this is a new problem that has not happened before, your best advice is to call/contact the seller and ask your questions.


  • Since this is a safety thing you should try to find an answer for your make of heater.
  • If you cannot contact the seller then try to find a telephone number on the plate on your heater as they should be able to assist you in finding an answer.
  • A friend has a similar heater and this is the answer that Tractor Supply gave her:
  • Tractor Supply's answer for a similar problem; Their technical told me to disconnect the thermostat bulb from the back of the heater and let it hang loose. It fixed it and they sent me a bracket to hold it away. It was sensing the heater temp and not room temp.
  • The heat sensor is sensing the heat from the heater it needs to sense the air away from the heater.
  • Don't cut, rip out or destroy the sensor or the heater won't work at all.

It is probably overheating. If you haven't had it long, it may still be under warranty.
