Why does my EQUATION WILD 2 3300 W construction heater heat up and then blow cold air?

Question

Accepted Answer

If your EQUATION WILD 2 3300 W construction heater heats properly and then starts blowing cold air, several causes may explain this behavior:

1. Thermostat operation

The built-in thermostat may stop heating when the ambient temperature reaches the programmed value. In this case, the device continues to circulate air, which may then be perceived as cold.

2. Selected operating mode

Check that the heater is set to "heating" mode and not to "ventilation" or "cooling" mode if the latter is available on your model.

3. Overheating protection

In case of overheating, the heater may go into safety mode and stop the heating element, resulting in a blast of cold air to cool the device. Ensure that the air vents are not obstructed and that the device is placed in a well-ventilated area.

4. Technical issue

If none of the previous checks resolve the issue, it may be an internal malfunction, such as a fault in the thermostat, fan, or heating element. In this case, a technical inspection or repair may be necessary.
