Hi Guys,

My propex blows air but won't ingite. The light on the thermostat isn't flashing at all. I read the following in the manual though:

Manual Overheat Cut-Out. The HS2000 incorporates an overheat cut-out which has to be reset
manually. If the heater reaches an unusually high temperature during operation the cut-out
will disengage the gas solenoid valve, cutting off the gas supply to the burner. The operation
of this cut-out could be caused by either a restricted hot air outlet or air inlet, or the heater
being switched off by a battery isolating switch depriving it of its purge cycle. To find the cutout,
remove the electronics cover on the heater and look for it positioned above the PCB with
2 yellow wires

I think this is what has happened to my heater as I was playing around with the leisure battery whilst it was on at some stage. A friend of mine has the same heater and it is in a much easier place to access so he removed the electrics cover but we couldn't see any obvious. The only part that had two yellow wires going to it was attached to the side but we couldn't see any button on it? Does anyone have a picture of what I am looking for by any chance to reset it?

Thanks,
Tim.

First thing - the manual says yellow/red wires!
Second - is there a flash code? 4 is for the thermal cutout. Without one I would expect something like low voltage to be the problem preventing it reaching error noting stage. ( I know nothing of these so am stabbing in the dark here)
Why they don't use an automatic reset one is beyond me but then I suppose some people would not bother with clearing the fault.

There is a pic of the reset in it. (looks like red/white wire to me!!!!)
I can't see the fuse on the circuit board though - must be on the other side. (Propex do say it is hidden!)

Hi Oldie,

The quote I posted was pasted from the manual. It appears there is a pre-2010 model and a pos 2010 model. Mine has two yellow wires but the picture you found in the JK thread is the component I thought it might be so you've confirmed that for me. I can see the little red button and thankfully I can just about reach it through the hole in the front of the heater so no need to remove the heater and disturb the pipework.

Thanks for your help.
Tim.

It would make more sense for the reset button to be accessed from the outside.

Absolutely!
