Thermotop C doing something strange.

Not sure I understand this.... It has just randomly started doing it.

My thermotop C's main power is from a large circuit breaker, which normally is off when the vehicles not in use. It then has an on off switch, 12v feed, to turn it on. It's just the Rover 75 unit. Simple on off.

Normally....
Turn on breaker (give heater power). Nothing happens. It sits quiet till the 12v On signal is turned on.

Now......
Turn on breaker, and the fan in the burner runs for about 30 seconds, progressively running slower and slower till it (presumably) stops. It goes inaudible.

If you actually run the heater, it fires up, works fine, then turns off normally. Fan off completely. Does so till next on 12v signal.

But kill the power completely and it does this strange this with the fan.

It's been working fine for months without doing this.

Could water getting into any terminals do this? I was washing it at the time and it just started up the fan randomly.
