Heater has behaved perfectly all year on the occasions we've needed a bit of warmth. Ran all last weekend last weekend and started and ran okay last night, I turned it off by mistake about 9 ish, tried to turn it back on and nothing! All that happens is the fan runs very slowly but the unit doesn't even attempt the start up sequence. Volts are good, any ideas guys?
I'm guessing a sensor problem but not sure and wouldn't know which one.

It's cold on here!
 
Sounds suspiciiously ECU ish, either that or a temperature sensor thinking its at temperature already if not a true marine unit (heater in control idle state, non marine will run slowly to sample incoming air temperature, marine will have remote sensor) What model. and what derivitive, printed on the ID lablel.

Could well be he internal sensor then, if you don't already have one manuals are easily found on line, though service bulletins are not, the stuff you need is pretty generic though so the on line manual will be adequate, or I can email you one if you drop me a PM.
 
I have had 3 erberspacher heater things (when I say heater I'm mean useless pile of carp) -the way to fix it is to disconnect all the pipes and connections, seal them off and chuck it in the sea and get your life back (do I sound bitter?)

buy a hot oil radiator, or better a good woolly jumper, much better still a girlfriend/wife (or whatever makes your boat float) far more effective, what ever, don't spend any more money on it, book into a hotel if its a bit too cold - it will be much cheaper and less stressful in the end.

Made me laugh too, or you could just properly fit a good heater, have it set up correctly, give it decent fuel, look after it and don't just expect it to sit there neglected from one winter to the next, and accept that sometimes things don't last forever and you will get good payback.
 
There seems to be 3 sensors, one says temp on the terminal block, circuit is open on this one. Another one is marked Ohs gn, this one sits on top of the combustion central area, circuit is closed on this one. Other is marked mot br, this is on the air in side, circuit is closed on this one.
Is there any way of testing these little buggers?
 
The sensor on the PCB is the sensor for sampling the incoming air, the first one on the HE is the overheat sensor and the one closest to the heat outlet on the HE is the flame sensor. The sensor on the PCB should read between 1800 & 2200Ω and the Flame sensor should be 900 to 1100 Ω cold and hot up to 2200Ω Do you have the factory workshop manual as it has all the values and test methods in it. P.M. me with an email address if you want one, manky scanned copy but perfectly legible.
 
Can't remember it being free, but it was a set price per quarter. Seems to actually work out cheaper over the year now. Yes bring blankets, Dave and Colleen might need them ��
James boat isn't as warm as it used to be nowadays either
