How to Troubleshoot Dometic Furnace Error Code E1

Dometic is a leading manufacturer of residential and commercial heating, ventilation, and air conditioning systems. Dometic furnaces are known for their advanced technology, superior performance and reliability. But like all things mechanical, these furnaces are prone to operational issues from time to time. When the furnace is working correctly, an error code will trigger the unit’s self-diagnostics and shut down automatically until repairs can be made. However, if you don’t understand what each error code means or how it might impact your furnace operation, you could end up with a more serious problem on your hands. This article covers everything you need to know about Dometic furnace error codes so that they remain nothing but an inconvenience in the future.

What does E1 in Dometic error codes mean?

E1 stands for “Discharge Air Temperature Sensor”. This error might be caused by a dirty sensor, a bad sensor or a broken sensor. A dirty sensor needs to be cleaned, a bad sensor needs to be replaced and a broken sensor needs to be replaced. When the air temperature sensor detects a temperature rise in the furnace, it activates the burner to warm the house. If the sensor is dirty, it could be reading a false temperature rise, which could result in the burner activating at the wrong time, resulting in higher gas bills. When a sensor is broken, the furnace will keep trying to start, but it won’t be able to. That’s what happens when you get this error. It’s rare, but it can happen.

E2 in Dometic error codes

E2 stands for “Discharge Air Flow Error”. This error is usually caused by a blocked sensor. When the sensor is blocked, the furnace will try to operate normally, but it will end up shutting down because the sensor reading is incorrect. Once you unclog the sensor, the furnace should start operating normally.

E3 in Dometic furnace error codes

E3 stands for “Low Discharge Air Pressure”. This error is usually caused by a dirty or clogged sensor. When the sensor is dirty or clogged, the furnace will try to operate normally, but the sensor reading will be incorrect. Once you clean or unclog the sensor, the furnace should start operating normally.

E4 in Dometic error codes

E4 stands for “High Discharge Air Pressure”. This error is usually caused by a bad sensor. When the sensor is bad, the furnace will try to operate normally, but the sensor reading will be incorrect. Once you replace the sensor, the furnace should start operating normally.

E5 in Dometic error codes

E5 stands for “High Discharge Air Temperature”. This error is usually caused by a dirty or a clogged sensor. When the sensor is dirty or clogged, the furnace will try to operate normally, but the sensor reading will be incorrect. Once you clean or unclog the sensor, the furnace should start operating normally.

E6 in Dometic furnace error codes

E6 stands for “High Burner Temperature”. This error is usually caused by a dirty or a clogged sensor. When the sensor is dirty or clogged, the furnace will try to operate normally, but the sensor reading will be incorrect. Once you clean or unclog the sensor, the furnace should start operating normally.

What does E7 mean?

E7 stands for “Discharge Air Pressure Sensor Error”. This error is usually caused by a blocked sensor. When the sensor is blocked, the furnace will try to operate normally, but the sensor reading will be incorrect. Once you unclog the sensor, the furnace should start operating normally.

E8 in Dometic errors

E8 stands for “Excessive Charge Air Temperature”. This error is usually caused by a dirty or a clogged sensor. When the sensor is dirty or clogged, the furnace will try to operate normally, but the sensor reading will be incorrect. Once you clean or unclog the sensor, the furnace should start operating normally.
