Last week I posted a problem about a wall furnace not working. Just to
remind everyone:

There are 2 Vanguard DNV25NB gas wall furnaces in my fathers condo. ( I
believe Vanguard and Dynavent are the same company).
One of the units is not working. Just the fan comes on, but no igniter.

I tested the igniter with an ohmeter and it was good. Next I checked to
see if I was getting 110V at the igniter and I am not. So now what do I
do at this point?
On the other unit that is working, I can faintly hear some kind of
relay click right before the ignitor is lit. Is the relay part of the
ignition module?
