Mike,
Do you think that it would be OK just to spray them with a c02 fire
extinguisher?

Fill a cup with ice water and submerge the vents wait a few minutes and
then turn them on. Or remove the vent heaters and put them in the
freezer, using an ohmeter see if there is continuity through the
thermostats.

Robert,
The fuel vent heaters and the lift detector (stall warning switch) have
temperature control on them so that they will not feel hot to the touch.
The fuel vent heaters (at least on my bird) do not feel hot on a cold
day, however they are warmer than the surrounding under wing skin. If
you get a definitive answer about testing please share. Quite some time
ago I made a similar post and did not get a complete reply from anyone.

Commanders-
Does anyone have a fool-proof method for testing the fuel vent heaters?
On a whim I decided to test them by turning on the battery, connecting
the buses and activating the L/R Pitot and Fuel Vent heaters.
Pitots heated up enough that you could fry an egg- but the fuel probes
did not warm even slightly.
This made me wonder if the fuel vent heaters are load-shed without a
generator on-line? (Yes yes- sometimes I have trouble keeping the big
airplane stuff and the Commander stuff segregated in my brain=85.you
should have seen me flaring at an eyeball height of 70=92.. HAHAHAH=85.
Oh boy=85.fortunately it turned out okay for everyone except my ego=85)
We=92re getting into the ugly part of the icing season out here- and
I=92m going to be making a bunch of trips over the mountains during the
winter- so I want to make sure my ice survival equipment is in top
working condition.
