| Subject: | Flap Motor Failure |
At about 70 hours my flap motor likewise failed. I did not take it apart
but removed it from the mounting and sprayed the motor only down with some
brake cleaner, the kind in a spray can that leaves no residue and flushed
it out real good. Put back in the ship and it's been working fine for
another 100 hours so far. Beats taking the brushes out and in!

Subject: RV-List: flap motor Failure?.
From: thomas sargent <sarg314@gmail.com>
Thursday morning when doing touch and goes in my 6A my flap motor stopped
working. I landed and raced off to work and got back to it this morning.
It will work for a while and then fail. I removed the switch (a high
quality, sealed mil-spec switch) and tested it a lot on the bench - it
never failed, I put it back in and the motor was intermittent. I removed
the panel to access the motor and tried shaking the wiring and
disconnecting and reconnecting the connector I have installed there, all to
no effect. Failures didn't seem to correlate with anything Then I made a
mating connector with 2 bare leads so the next time it failed I could
disconnect the motor, connect the test connector and measure the voltage to
see if voltage was getting to the motor. Of course, after that I couldn't
get it to fail again. The connectors are good quality automotive ones with
gold plated pins. I haven't had any failures of these connectors and I
used a lot of them.
So my question is about Van's flap motor typical failure modes. My
suspicion is that the wiring and switch are OK - I suspect the motor.
Can/does the motor itself often fail this way? I vaguely recall people say
these motors aren't very reliable.
