  If your Venmar Fan displays error code E50, try the following steps: First, unplug the unit, inspect the wires, and then plug it back in. If the problem persists, remove the wall control from the wall and test it with a short cable. If it works, install a new cable to the wall installation location. If the issue remains, test the air exchanger with a spare wall control; if it works, replace the wall control. As a last resort, replace the electronic assembly.
