I have a Venmar Pro250 HRV. It’s been installed for five years and worked great. And however now the damper is not functioning so I cannot exchange air. I’m trying to determine if the motor is faulty or if it is the circuit board. Does anyone have a schematic? Particularly of connector J12 that goes to the damper motor from the PCB. I’ve of course tried Venmar’s website and technical support with exactly zero success. TIA

The damper on my AVS Solo 1.5 has a connector with 2 conductors & runs on 120VAC. It's a locked rotor motor. I had to replace mine after 20 or so years. Check to make sure the mechanism is not getting caught on anything in the unit. I would try disconnecting the motor and run 120V to it to see if it moves.

Well I spent quite a bit of time tracing wires and checking components and outputs. Then I happened to see a paragraph in the manual that mentioned the “boot sequence”. The lightbulb came on (dimly)! I unplugged it, waited 30 seconds, and plugged it back in. Works perfectly.
Lots of people contact me for tech support on various things and the first thing I always ask is if they’ve tried a Mexican reset. I’m so dumb sometimes!
