I hope we did not tell you to warm up a lager.  The primary fermentation of
that yeast should be in the range of 48F to 56F.  The yeast you used was
2007 Pilsen Lager.  You were already at the top of the temp range in the
closet before you warmed it up.  The beer has probably fermented quite a bit
already due to the warmer temp.  You may have some off flavors as a result.

Take a gravity reading.  That is the only way to know what is really
happening.  Let us know what that is, and I am sure someone can offer advice
on what to do next.

Cheers,
Mike

i'm a little bit worried about a batch i just brewed.  it's a light
pilsner.  i used a starter with wyeast pilsner yeast.  the airlock on
the bucket started to bubble lightly about 24 hours later, but was very
slow (about once every 5 seconds).  then after 36 hours, no more
bubbles.  the guys at the local homebrew shop -- and many posts here --
said that the temperature was probably too low (the closet is between 58
and 63 degrees).  so i heated up the closet to 70, but nothing has
happened after 2 more days!  i checked all seals, too.

should i wait more?  would pitching more yeast work?  thanks for any
advice.

Hmmmm, never brewed a pilsner but looking at Wyeast Labs site your original
closet temp sounds in the ball park for fermentation depending on the strain
of pilsner your brewing. Did you areate the wort well prior to and just
after pitching? What temperature did you pitch at? If I can recall the last
time I brewed a lager you still want to pitch in the low 70's F and then
once fermentation begins drop the temp down into the fermentation range.

If your sanitation is good you can try repitching to save the batch. I've
done this before sucessfully but never after three days.

Good luck!

What type of airlock are you using?  I have my very first batch fermenting
right now in a plastic bucket. It is an IPA from 4lbs liquid and ~2lbs dry
 no scale. guessed from 3lbs bag ) with a starting gravity of 51. The temp
has been steady at 69. I am using a 3 piece airlock. The airlock started out
at 1 "glug" every 10 seconds on morning 2 and it maxed out at 1 "glug" every
4 1/2  seconds on morning 8. On morning 9 ( this morning ) it was at 1
"glug" every 45 seconds. So if you think 5 seconds is slow...

Add to the question of whether you aerated well, did you pitch a big
starter?

Heating it up is not good.  Your temperature is actually too warm
already.  You should probably be around 50F.  

My guess is that you didn't oxygenate the wort very well.  This is
very important, especially for lagers.  You should mix up the wort
after it is cooled and get as much oxygen disolved in it as you can.
It is really too late now.  You can try and get a yeast nutrient and
make a solution with it (in boiling water).  Add that to your
fermenting wort and see if it will snap out of it.
