good jorb sweaty, totally glad we’ve been paying for a maintenance contract on this thing all this time
Upon having the staff working below complain they were pretty much freezing down there and looking in this confusing mess and seeing a suspiciously weak output air temperature… it was time to go investigate so I can tell the HVAC company how to fix it.
They do not successfully ever do diagnostics. I basically have to tell them what’s wrong and have them fix it.
Sometimes I wind up fixing it anyway because they have absolutely no clue how.
This is hopefully not entirely one of those.
but at least there’s no variable frequency drive involved. just a toasted drive belt that’s about two days from snapping off like an over-fried onion ring and leaving us shivering.
i don’t know i’m six days into what should have been a four day work week and my brain is just a bunch of aktivschaum.
anyway I found the thing having trouble lighting, short cycling, and periodically letting out gas farts because the “intermittent pilot” (a high voltage spark ignitor) was all fouled with crap… along with the venturis to the burners…. and pretty much….. everything
can i go home already?? youtube is recommending a video to me called “calm your anxiety”.
Apparently that heat exchanger isn’t original. We had another one of these units on which the heat exchanger cracked and Modine has entirely washed their hands of this series – no parts available anymore. The new one that was installed in its place is twice the physical size, makes huge banging and whistling noises, took ONE YEAR from order to delivery, and required a weird custom roof curb to sit in. Charming.
