Another service call to a local development that was installed by my former employer. First let's see if Joe Homeowner has been taking care of his system? Nope.
The leaf shaped clean spots are where the car air fresheners were stuck to it. I removed that and fired it back up. The board was flashing the low flame signal code, cleaned that and got it back running.
Some more pictures of this wonderful install:
This is downflow installed on the 2nd floor. The return plenum is installed during the construction phase of the house, then when the furnace is set they attach their crappy filter box and blank it off. I would've at least made a nice transition, but they don't pay their piece rate installers for that. The Honeywell fresh air controller is mounted near the ceiling where the homeowner needs a ladder to reach it.
This is one of my pet peeves:
This furnace comes with bushings so that you can route the low voltage into the cabinet. Yeah, most of it is in loom, but how hard is it to use a bushing?
