My Dyson heater switches off even if air temperature has not been reached and a message E7 is shown. Does this mean it is a faulty device?

The gas valve is not sensing flame, and the unit shuts down on safety.

Chances are the flame sensor is bad, its a common problem.

If its a thermocouple you can buy one for 10 bucks, If its a newer style they can usually be had for less than 30.

They are easy to replace ad they are usually installed with two screws and one to two wires.

They sit directly in the flame pattern in front of the burners.

A service call should only cost you 250 or less for the repair, but you can do it yourself for less than 50 (including gas to drive to the HVAC supply house that sells your brand unit.)

You will need the model and serial #s when locating the parts.

The heater in your car depends upon a flow of hot coolant going through the heater core in order to get hot air into the car. If the heater core is partially plugged, it will restrict the flow. If you have a head gasket that is putting exhaust into the cooling system, it will eventually get into the heater core. When this happens there is no coolant in the heater core to make the air warm. If the water pump vanes have corroded away the result will be very poor coolant circulation causing the heater to not blow hot air. If your car is equipped with a heater control valve that is not functioning properly, the coolant flow will be restricted. One or a combination of these factors is likely the culprit in your case.

To attempt to clean the core, you must flush the system multiple times. If this does not work, the core cannot be cleaned and must be replaced.

lower the tempature setting so the residual heat is the right temp your looking for
