While off, something fell through the grid. I opened the fan heater to remove it. It now doesn't blow hot air (setting 1 or 2) for more then 4/7 seconds. Cold air is fine.
It seems to me that the thermostat function is playing up but I'm not an electrician, the warranty is gone, I cannot afford a new one and according to GOT: "Winter is coming"
I've attached 1 photo as I'm not allowed to post more than 2 links.
I've circled what seems to be the thermostat (1) and where the trigger to stop the fan is (2). If the trigger is opened the fan doesn't work but when closed it does. Nothing is/has burned.
Here is #1 that I thought would be a kind of thermostat or resistance.
If something had burned I would have understood. I've 'only' moved an object out of the way. It still works for cold air and also starts blowing hot air for 4 to 7 seconds until the trigger 'click' (sound) open. Then I have to wait (2 min approx) for the thermostat (non-damaged) to cool down (I guess), the click sound happens again and the trigger is closed and it's ready to go again for a few seconds. Turning the thermostat button does not change anything.
