Subject: Re: Fridge Fan ?
Content-Type: text/plain; charset=us-ascii
The fridge fan is completely independent of the fridge setting or
whether the fridge is even on. It runs whenever the temp switch behind
the fridge tells it to. If the sun is shining on the fridge side of the
van it will often heat up the area behind the fridge enough for the fan
to come on. This may seem strange but it was done this way for a reason.
If your fan comes on when the fridge is off and that side of the van is
not in the sun then the temp switch is suspect. Is it the original one?
The Fridgemate series of replacement fans come with a new temp switch
that turns on at way too low of a temp for use in the stock temp switch
location. If someone put one of these in to replace the stock one then
that is your problem.
The second wire that you refer to is the wire that controls the relay
for the 12 volt heater element in the fridge. It comes from the
alternator warning LED circuit and only allows the fridge to run on 12
volts when the alternator is charging. This keeps the fridge from
quickly running down the battery. The relay on your early model is
screwed down on the top of the fridge. Later Westys have the relay under
the driver's seat and have slightly different wiring for the kitchen
equipment and 2 fuses behind the driver's seat. The newer Bentley shows
only the later wiring but mislabels it as applying also the the 80,81
models which are in fact different.
