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..you should have seen me flaring at an eyeball height of 70'.. HAHAHAH.. Oh boy..fortunately it turned out okay for everyone except my ego.) We're getting into the ugly part of the icing season out here- and I'm 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.

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. Moe N680RR Proud Holder of The Golden Pedal Award From: Robert S.

Re: Commander-List: Fuel Vent heat Test? 1. The vent heaters-are not-generally controlled-by a switch, just th e breaker and an internal thermostat.- On smaller planes, its just a ligh t bulb. - 2.- $2.00 will buy you a can of electrical contact cleaner or just a can of compressed air (for cleaning computer parts). and a $10 volt-ohm-meter. - 3. Open the inspection port, you'll need access to the leads at the vent he ater. Disconnect the power lead and test between the power and the heater. - It should show an "open" circuit (if the temp is above ~40F). - 4.- Give the vent/heater body-a shot of cleaner to chill it down.....Th e heater has a thermostat which should close and the VOM should show power going to the heater.- (it should also feel warmer to the touch if only fo r the time it takes to warm up to ambient temp. - - Another way is to remove the vent heater and do the same test on a bench, i nside where its warmer. - If you are still unsure, spend the $65 to have your A/P do it and have him swear on a stack FAA manuals.- I prefer to wait in the customer lounge an d chat up the FBO secretary.... ---- - what was that saying...."Nothing in life is sure....less so..........- oh well, I forget." - wer --- On Mon, 11/17/08, Moe-rosspistons wrote: From: Moe-rosspistons Subject: Re: Commander-List: Fuel Vent heat Test?

Randazzo" Subject: RE: Commander-List: Fuel Vent heat Test? Willis, et al- Thanks- these are all helpful. I'm not shy about having my shop looking at squawks. I do quite a bit of work with them on a few different airplanes- so I get top notch service and no BS whatsoever when it comes to billing or having someone stop by the hangar to look at something that catches my attention. By the same token- it occurred to me that I don't really know enough about those vent heaters to determine if they are working properly or not- so I thought it was important to correct my deficiency.

The vent heaters are not generally controlled by a switch, just the breaker and an internal thermostat. On smaller planes, its just a light bulb. 2. $2.00 will buy you a can of electrical contact cleaner or just a can of compressed air (for cleaning computer parts). and a $10 volt-ohm-meter. 3. Open the inspection port, you'll need access to the leads at the vent heater. Disconnect the power lead and test between the power and the heater. It should show an "open" circuit (if the temp is above ~40F). 4. Give the vent/heater body a shot of cleaner to chill it down.....The heater has a thermostat which should close and the VOM should show power going to the heater. (it should also feel warmer to the touch if only for the time it takes to warm up to ambient temp. Another way is to remove the vent heater and do the same test on a bench, inside where its warmer. If you are still unsure, spend the $65 to have your A/P do it and have him swear on a stack FAA manuals. I prefer to wait in the customer lounge and chat up the FBO secretary.... ---- what was that saying...."Nothing in life is sure....less so.......... oh well, I forget." wer --- On Mon, 11/17/08, Moe-rosspistons wrote: From: Moe-rosspistons Subject: Re: Commander-List: Fuel Vent heat Test?

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. _____ From: moe-rosspistons@hotmail.com Subject: Re: Commander-List: Fuel Vent heat Test?
