An Eber problem........It must be coming on winter!

[Pladdatoo]

A D1LC compact......

Ran perfectly until recently when it has decided to only run for about 5-8 minutes before entering shutdown mode and switching itself off.
When running, it runs up fine, producing great heat, but the fuel pump will then stop clicking and she enters a full and proper shutdown.
Can't be power as after that amount of time the power draw would be dropping off.
Plenty of fuel ( I run it permenatly on paraffin).

I am suspecting some thing to do with the thermostat.......it has an external thermostat located in the cabin, so deffinately not getting up to temperature and shutting the unit down. However, is the a way I can check whether it is faulty, or the internal thermostat is kicking in for some reason?
Thoughts appreciated....
Thanks

Is it possible that the ducting has been squashed, restricting air flow and triggering an overheat shutdown?

An interesting thought/idea, however, flow through my one and only vent into the saloon remains as it always has with no apparent restriction or reduced flow.

It sounds as though the overheat sensor may be faulty, although that would only be the simplest cause. If you visit the Le Tonkinois website, they give correct resistances for the sensors so you can check them out. I don't think it will be the thermostat as when the cabin reaches temperature the heater should go to minimum setting rather than a full shut down.

Is there a restriction at the inlet side..? Even something like a plastic bag partially covering the inlet can be enough to cause overheat.

Interesting, haven't looked there.

I will also check the resistances as rob2 has suggested

I would have expected the thermostat control to either cause the fuel pump to either speed up or to slow down the pump - not to shut the unit down entirely.

I assume what you mean by a 'full and proper shutdown' is that you notice that the fuel pump stops ticking but that the fan continues to run until the unit is cool.

Yes, so would I.

That is correct and is exactly what happens.

The manual suggests it will shut down for various reasons. Overheat is one. Or low voltage, low fan speed, incorrect fuel pump quantity. The system should retain the fault code, so if you can't easily fix it a dealer will be able to retrieve the fault code.
