David & Dave,
My stock fan was a new replacement from Dometic Dealer/Service Shop.
It was identical and new. It definitely tested at 220ma (though the Dometic
RM182B owner's manual claims .6 watts on page 7.) I bench tested it so it
definitely was not jammed. Also, the fridgemate definitely tested at 65ma
and blew LESS air than the stock fan. I tested these things pretty
thoroughly. I guess there could be some variation, but I'm sure that's what
my fans tested at.
I'll repost my fridge fan article for those who are interested.
Regarding the pulling the fan fuse, I'm pretty sure he was pulling it while
the fridge was off/not running. His problem it seems is that the fan runs
while his van is sitting stored in his garage... fridge not on. The fans is
activated by a heat switch that has noting to do with the fridge being on or
not; just the temp of the fins. However, my 90 Owners manual claims that
they come on at 126 F and turn off at 108 F (p. 7). This means they will
come on during a hot day even with the fridge off.
