    First service call after being on the job for 1 week. Condensate leak. Called my boss telling him we needed a plumber out here cause there was water in the A/C, and there must be a leaking water line somewhere.

    Most people don't like to work on them because they don't understand them. The Lennox pulse was a great furnace.. We still have about 10 customers that have them and they love them.. The most common problem I run into is dirty diaphragm...but first big time mistake you can do is bypass a safety switch, anything happens to a family you would never be able to live with your self.

    Pinchy bug stuck in contactor, causing compressor to single-phase. Only took 6 hours to find! I was da MAN that day! Saw the same thing with a spider 20 years later...took a lot less time to troubleshoot.

    Sure do,I changed a ignition control module in an Amana HTM package unit. I was 19 and scared that I was going to mess it up.

    My first call was for a company I didn't even work for, my brother did. It was when spark ignition just came into widespread use. He called me because of a problem they were having a hard time finding, I found a bad connection on a Fenwal ignition control plug on a Heil.
    Nothing is magic, it works or doesn't work for a reason.

    No heat, every thing sequences but no fire. I feel gas valve opening so its gotta be a problem. Told the tenant ide be back first thing in the morning. So i goto johnstone and get a very nice utube manometer. I get back and am ready to hook it up when i see a red tag on the ball valve stating "furnace wont fire" or something like that. Turn the gas on and every thing is fine. I never did find a problem and never had used the manometer in the feild since.but 6 months later im much wiser.

    Been with company 6 years doing mainly new construction. One day boss says your going on rotation. WTF I am no service guy. First call comes from one of the main builders we work for having a party Friday night with no ac. Try to pawn the call off but no takers. Go out to the residence and I look like a deer in the headlights. Says heater is in the back closet in basement where the party was. Open the door and remove a coat to turn on light switch and voila. AC fires up. Someone hung there coat and turned off switch and I was a hero. That is of course until my next call. Another story for later.
    You need to put the phone down and get back to work!

    Jmac's rule of switch flipping~~~~~take the cover off, bang around for a few minutes, put it back together and get a ∆T (look like you know what your doing), Declare yourself the Master of all cooling, leaving the owner in stunned amazement at your greatness

    seriously, it works everytime

    My boss is always after me to come up with something like a "bad connection" or some other crap when they put batteries in the stat backwards or brush something against a furnace disconnect. Or inadvertently hitting the run program function when they never use it and it defaults to the factory specs.

    I've never been able to bring myself to do it. Explain to them how it works and save them an inconvenience down the road - you still get the trip/diagnostic.

    Change out an in warranty 90% inducer assembly (diagnosed by installers) and add a 1/2" ball valve on the gas line where they tee'd off an existing line.

    Licensed... or hack... <grin>

    Seriously... OLD belt driven gas furnace... with thermocouple gas valve. Bad thermocouple. Cleaned and tightened EVERY connection in the heat circuit. HO said it worked better than it had in years...

    I have scratched my head more on Train RTU's (Voyagers) than anything... however I never have worked on (or even seen) a Pulse. I would like to play with one... get the book, learn how to work with it... and master it (just because it is there)... however it appears they are almost all gone... so I may never get to.

    Good thread... lots of good stories.
